Which channels you can publish to

Only these. Do not offer a user anything else, and do not try to post to it. Postemi's server carries inherited code for many more providers; that code is not enabled and not supported. Postemi adds channels over time, so integrations:list (below) can show one that is not in this table yet.

Channel	`identifier`	Status
X (Twitter)	`x`	Live
Facebook (Pages)	`facebook`	Live
Instagram (business account through a Facebook Page)	`instagram`	Live

LinkedIn (member feed)	`linkedin`	Live
TikTok	`tiktok`	Live
YouTube	`youtube`	Live
Threads	`threads`	Live
Bluesky	`bluesky`	Live

Pinterest is live. A pin needs a board id in --settings; look it up first (see PROVIDER_SETTINGS.md).

The BETA channels connect and publish, but Postemi has not tried them with many real accounts yet. Say so when the user picks one. Many need settings (a title for WordPress, Dev.to, Ghost and Hashnode; a picture for Pixelfed; a community for Lemmy; a list or audience for the newsletters); check integrations:settings and PROVIDER_SETTINGS.md.

Google Business Profile, LinkedIn Pages and Snapchat are coming soon. Those platforms have not approved Postemi yet, so the user cannot connect them. Do not schedule for them; personal LinkedIn profiles (linkedin) work today.

integrations:list is the truth. The table says what Postemi supports; that command says what THIS user has actually connected. Check it before you schedule anything, and never post to an id that is not in its output.

Never assume another provider exists. If a user asks for Reddit, Medium, Farcaster, VK or anything else that is not in the table, the answer is that Postemi does not offer it today. Do not build a --settings payload for it.

⚠️ Two Hard Rules (Read First)

Rule 1: Authenticate before anything. All commands fail without valid credentials.

Rule 2: Every file passed to -m (or to image/media fields in JSON mode) MUST first go through postemi upload. Raw filesystem paths (image.jpg, video.mp4) and external URLs (https://example.com/...) are NOT accepted by the publishing pipeline. TikTok, Instagram, YouTube, and most other providers reject anything that isn't a Postemi-verified URL. Always:

bash

RESULT=$(postemi upload <file>)
URL=$(echo "$RESULT" | jq -r '.path')
postemi posts:create ... -m "$URL" ...

If you see -m "something.jpg" anywhere below, treat it as shorthand for "the .path you got back from postemi upload something.jpg", never a raw local file.

Output contract

Every command prints its JSON result, and nothing else, to stdout; status lines, warnings and errors go to stderr, and every failure exits 1. So postemi upload x.jpg | jq -r '.path' is always safe, with no stripping needed. Unknown flags are an error, not silently ignored. If a flag is rejected, it does not exist; do not retry with variations.

⚠️ Authentication Required

You MUST authenticate before running any Postemi CLI command. All commands will fail without valid credentials.

Before doing anything else, check auth status:

bash

postemi auth:status

If not authenticated:

Sign in: postemi auth:login opens a browser, and the human approves it. You never see or handle a key.
No account yet: postemi auth:signup creates one, see below. Only when the user asks you to create a Postemi account for them. They can also sign up at https://postemi.com/app/signup, which starts a 7-day free trial, and then run postemi auth:login.

Creating an account for the user (no free trial)

When the user asks you to make them a Postemi account and they have none:

bash

postemi auth:signup --email anna@example.com
# → {codeSent:true, terms, privacy, timezone, language, next}   (no terminal: the code is on its way; `next` is the exact second command, every option kept)
postemi auth:signup --email anna@example.com --code 123456 --accept-terms [--workspace-name "Anna's Cafe"] [--timezone Europe/London]
# → {created:true, workspaceId, workspaceName, trial:false, credentials, next}

Run it with --email only. Postemi e-mails the user a six-digit code (valid 10 minutes). Ask the user to read the code to you.
Show the user the terms (https://postemi.com/terms) and the privacy notice (https://postemi.com/privacy) and ask whether they agree. Pass --accept-terms ONLY after they said yes; never decide it for them.
Run it again with --code and --accept-terms. The CLI keeps the sign-in the same way auth:login does and never prints it.
There is no free trial on an account made this way, and until the user pays, only the billing:* commands work. Next: billing:plans, confirm a plan with the user, billing:subscribe, give them the link. Channels are connected by the user in the web app after paying.
You keep working for the user only on a plan with API access (limits.apiAndMcpAccess: true in billing:plans). Basic has none: if the user picks it, tell them BEFORE they pay that you will not be able to schedule for them afterwards. billing:subscribe answers with apiAndMcpAccess: false and prints the warning on stderr for such a plan.

Exit 1 with "already has a Postemi account" (HTTP 409) means the address is taken: the user signs in with postemi auth:login instead. A wrong or expired code: run step 1 again for a new one.

postemi auth:status reports a valid key of a workspace that has not paid yet as authenticated: true, apiAccess: false, reason: "no-plan" (exit 0). It is not an invalid key; do not run auth:login for it. Only the billing:* commands work until the workspace is on a plan with API access.

Do NOT proceed with any other commands until authentication is confirmed.

What a key can and cannot do

Keys are per person, named, and scoped. They are stored hashed and shown exactly once, at creation, in the web app under Settings → Developers. A lost key cannot be recovered. It can only be rotated.

Two limits apply to every request, and both explain 403s that look like bugs:

Scopes. A key carries a subset of posts:read, posts:draft, posts:publish, channels:read, channels:write, media:write, analytics:read. A route refuses a key that lacks its scope.
The owner's current role, re-checked on every request. A key can never do more than the person who created it can do right now. If that person is demoted, their live keys narrow on the next request, with nobody revoking anything. So a key that worked yesterday can legitimately start returning 403 today with no change to the key.

A key can also be granted only some workspaces and only some channels. A request naming a channel outside the grant is refused even when the scope is right.

When you hit a 403, read the message. The CLI names the missing scope; the key is valid, so auth:login does not fix it. Do not retry, and do not try a different route to get around it. Ask the user to mint a key with the scope, or to have someone with the right role do it.

Core Workflow

The fundamental pattern for using Postemi CLI:

Authenticate - Verify or set up authentication (see above)
Workspace - postemi workspaces:list; if more than one and none is current, ask the user which, then postemi workspaces:use <id>. Channel ids belong to a workspace.
Discover - List integrations and get their settings
Fetch - Use integration tools to retrieve dynamic data (Instagram audioSearch; Discord and Slack channels)
Prepare - Upload media files if needed
Post - Create posts with content, media, and platform-specific settings
Analyze - Track performance with platform and post-level analytics
Resolve - If analytics returns {"missing": true}, run posts:missing to list provider content, then posts:connect to link it

bash

# 1. Authenticate
postemi auth:status
# If not authenticated: postemi auth:login   (no client id/secret, it is a device flow)

# 2. Discover
postemi integrations:list
postemi integrations:settings <integration-id>

# 3. Fetch (if needed)
postemi integrations:trigger <integration-id> <method> -d '{"key":"value"}'

# 4. Prepare
postemi upload image.jpg
#    or, when the file is on the person's phone / not on this machine:
postemi upload:link            # show the url to the person, they drop the files
postemi upload:files <id>      # what arrived; use each .path in -m

# 5. Post
postemi posts:create -c "Content" -m "image.jpg" -i "<integration-id>"

# 6. Analyze
postemi analytics:platform <integration-id> -d 30
postemi analytics:post <post-id> -d 7

# 7. Resolve (if analytics returns {"missing": true})
postemi posts:missing <post-id>
postemi posts:connect <post-id> --release-id "<content-id>"

Essential Commands

Workspaces

A credential may reach several workspaces (the user ticked "All my workspaces" at login, or made a multi-workspace key). The API refuses every request from such a key that does not name one, with 403 and the message "This API key spans several workspaces", so check first:

bash

postemi workspaces:list            # [{id, name, role, current}]
postemi workspaces:use <id>        # persists; every later command acts there
postemi workspaces:current
postemi integrations:list --workspace <id>   # one command elsewhere, without switching

Say the workspace name back to the user when they have more than one, and never pick one for them. After a switch, run integrations:list again: channel ids from the other workspace are invalid here.

Authentication

Sign in: device login

bash

# Opens a browser. No client ID or secret, the human approves the code shown.
postemi auth:login

# Check auth status (verifies credentials are still valid)
postemi auth:status

# Logout (remove stored credentials)
postemi auth:logout

How it works, so you can explain it if the user asks: the CLI calls POST /device/code, prints a short user code and opens the approval page in the browser, then polls POST /device/token until the human (signed in to Postemi) approves it and chooses which workspace and which channels the resulting key may reach. This runs inside Postemi's own backend; there is no separate auth service.

The CLI keeps its own sign-in after that; do not read, print or copy it.

Off a terminal (when you, an agent, run it) the CLI does not ask for a timezone: pass --timezone on date-taking commands, or run postemi config:set timezone Europe/London once. See "Date Handling".

The CLI talks to https://api.postemi.com. The MCP server, for chat clients, is https://mcp.postemi.com/mcp. Other hostnames you may have read about do not exist.

Upload link: when the file is not on this machine

postemi upload needs the file on disk. When the person has it on their phone, or you cannot see their filesystem, do NOT ask them to host it somewhere public. Mint a link:

bash

postemi upload:link
# → {"id":"kR3mQ7xP2nLa","url":"https://…","expiresAt":"…"}

Show the url to the person verbatim and say: open it, drop the image or video, come back and tell me it is done. It works signed out and on a phone. When they say done:

bash

postemi upload:files kR3mQ7xP2nLa
# → {"status":"ready","count":1,"files":[{"id":"…","name":"clip.mp4","path":"https://…","type":"video"}]}

Pass each path to posts:create -m. status: "empty" is not an error: they have not finished, or spoke before the last file landed. Ask them to check the page says "uploaded" and run it again. The link lives two hours; mint a new one if it expires.

Subscription (only when the user asks)

Four commands, the only place a plan is named. Call them only when the user asks about plans, asks to subscribe, or asks to manage their subscription; never suggest a plan or an upgrade otherwise.

bash

postemi billing:plans                                  # → {current:{tier,plan}, plans:[{plan,slug,monthly,yearly,limits}], trial, trialDays}
postemi billing:subscribe --tier pro --period yearly   # → {status:"requires_payment", checkoutUrl, checkoutId, plan, amount, currency, trial, expiresAt, apiAndMcpAccess}
postemi billing:status                                 # → {state, plan, period, currentPeriodEnd, payerIsCaller, pendingCheckout, apiAndMcpAccess}
postemi billing:manage                                 # → {portalUrl}

The flow:

Confirm the plan (Basic, Pro, Creator or Team; --tier basic, pro, creator or team, or the slug that billing:plans prints) and the period (monthly or yearly) with the user. Basic has no API access: if the user picks it, tell them BEFORE they pay that you will not be able to schedule for them afterwards.
Run billing:subscribe once and give the user checkoutUrl. The user opens it and pays with their OWN Link wallet or card. Do NOT pay with a one-time or agent-issued card, a virtual card number or any credential of your own: a Postemi subscription renews monthly or yearly, and a one-time credential fails at the first renewal, which ends the plan. --open opens the link in the browser of this machine; use it only when this machine is the user's own.
After the user says they have paid, run billing:status and check that state is trialing or active before continuing setup. It changes within seconds of the payment. If billing:status shows a pendingCheckout, hand that link back instead of running billing:subscribe again.
A live subscription is changed, cancelled or invoiced in the Stripe portal: billing:manage prints the link. Do not describe plans there.

These commands work before the workspace has a plan with API access (they are how it gets one). billing:subscribe and billing:manage need a full-workspace key or an OAuth token held by the person who pays (or a workspace owner when nobody pays yet); a scoped key is refused with a message that says so.

Rate limits

Tiered, per key, per route, per hour. Each route keeps its own bucket, so a polling loop on posts:list cannot starve posts:create.

Routes	Limit
Reads: `posts:list`, `integrations:list`, `integrations:groups`, `integrations:settings`, `posts:missing`, `posts:find-slot`, notifications	600/h (the `API_LIMIT` default; production sets 600)
Publish and delete: `posts:create`, `posts:delete`, `posts:delete-group`, `posts:status`, `integrations:trigger`	60/h
Analytics and channel refresh: `analytics:platform`, `analytics:post`, `/social/:integration`	30/h
Uploads: `upload`, `upload-from-url`	30/h
Upload links: `upload:link` 60/h, `upload:files` 600/h

The bucket is keyed on the hash of the presented key, so rotating a key starts a fresh allowance and the old secret's allowance dies with it. Exceeding a limit returns 429. Back off; do not retry in a tight loop: a retry storm just burns the next hour's allowance too.

Integration Discovery

bash

# List all connected integrations
postemi integrations:list

# List integrations belonging to a specific group (customer)
postemi integrations:list --group <group-id>

# List all groups (customers) as {id, name}
postemi integrations:groups

# Get settings schema for specific integration
postemi integrations:settings <integration-id>

# Trigger integration tool to fetch dynamic data
postemi integrations:trigger <integration-id> <method-name>
postemi integrations:trigger <integration-id> <method-name> -d '{"param":"value"}'

Creating Posts

bash

# Simple post (date is REQUIRED)
postemi posts:create -c "Content" -s "2026-12-31T12:00:00Z" -i "integration-id"

# Draft post
postemi posts:create -c "Content" -s "2026-12-31T12:00:00Z" -t draft -i "integration-id"

# Post with media (upload each file FIRST, see Rule 2)
IMG1=$(postemi upload img1.jpg | jq -r '.path')
IMG2=$(postemi upload img2.jpg | jq -r '.path')
postemi posts:create -c "Content" -m "$IMG1,$IMG2" -s "2026-12-31T12:00:00Z" -i "integration-id"

# Post with comments (each with own media, every file uploaded first)
MAIN=$(postemi upload main.jpg | jq -r '.path')
C1=$(postemi upload comment1.jpg | jq -r '.path')
C2A=$(postemi upload comment2.jpg | jq -r '.path')
C2B=$(postemi upload comment3.jpg | jq -r '.path')
postemi posts:create \
  -c "Main post" -m "$MAIN" \
  -c "First comment" -m "$C1" \
  -c "Second comment" -m "$C2A,$C2B" \
  -s "2026-12-31T12:00:00Z" \
  -i "integration-id"

# Multi-platform post
postemi posts:create -c "Content" -s "2026-12-31T12:00:00Z" -i "$X_ID,$FB_ID,$THREADS_ID"

# Platform-specific settings
postemi posts:create \
  -c "Content" \
  -s "2026-12-31T12:00:00Z" \
  --settings '{"who_can_reply_post":"everyone"}' \
  -i "$X_ID"

# Complex post from JSON file
postemi posts:create --json post.json

Managing Posts

bash

# List posts (defaults to last 30 days to next 30 days)
postemi posts:list

# List posts in date range
postemi posts:list --startDate "2026-01-01T00:00:00Z" --endDate "2026-12-31T23:59:59Z"

# Delete one post (one channel, with its thread or comments); other channels of its group stay
postemi posts:delete <post-id>

# Delete a whole group: the post on every channel it went to (group from posts:list)
postemi posts:delete-group <group>

# Change post status (draft ↔ schedule)
postemi posts:status <post-id> --status draft     # Move back to draft, terminates any running publish workflow
postemi posts:status <post-id> --status schedule  # Promote a draft into the publishing queue (uses the post's stored date)

Analytics

bash

# Get platform analytics (default: last 7 days)
postemi analytics:platform <integration-id>

# Get platform analytics for last 30 days
postemi analytics:platform <integration-id> -d 30

# Get post analytics (default: last 7 days)
postemi analytics:post <post-id>

# Get post analytics for last 30 days
postemi analytics:post <post-id> -d 30

Returns an array of metrics (e.g. Followers, Impressions, Likes, Comments) with daily data points and percentage change over the period.

⚠️ IMPORTANT: Missing Release ID Handling

If analytics:post returns {"missing": true} instead of an analytics array, the post was published but the platform didn't return a usable post ID. You must resolve this before analytics will work:

bash

# 1. analytics:post returns {"missing": true}
postemi analytics:post <post-id>

# 2. Get available content from the provider
postemi posts:missing <post-id>
# Returns: [{"id": "7321456789012345678", "url": "https://...cover.jpg"}, ...]

# 3. Connect the correct content to the post
postemi posts:connect <post-id> --release-id "7321456789012345678"

# 4. Now analytics will work
postemi analytics:post <post-id>

Connecting Missing Posts

Some platforms (e.g. TikTok) don't return a post ID immediately after publishing. When this happens, the post's releaseId is set to "missing" and analytics are unavailable until resolved.

bash

# List recent content from the provider for a post with missing release ID
postemi posts:missing <post-id>

# Connect a post to its published content
postemi posts:connect <post-id> --release-id "<content-id>"

Returns an empty array if the provider doesn't support this feature or if the post doesn't have a missing release ID.

Media Upload

⚠️ IMPORTANT: Always upload files to Postemi before using them in posts. Many platforms (TikTok, Instagram, YouTube) require verified URLs and will reject external links.

bash

# Upload file and get URL
postemi upload image.jpg

# EXACTLY EIGHT TYPES ARE ACCEPTED. Anything else returns 400 "Unsupported
# file type.". The server sniffs the magic bytes, so renaming the file does
# not help.
#
#   image/jpeg  image/png  image/gif  image/webp
#   image/avif  image/bmp  image/tiff              (max 10 MB)
#   video/mp4                                      (max 1 GB)
#
# NOT accepted: MOV, MKV, WEBM, AVI, SVG, PDF, DOC/DOCX, and every audio
# format. Convert first:  ffmpeg -i clip.mov -c:v libx264 -c:a aac clip.mp4
# See SUPPORTED_FILE_TYPES.md.

# Workflow: Upload → Extract URL → Use in post
VIDEO=$(postemi upload video.mp4)
VIDEO_PATH=$(echo "$VIDEO" | jq -r '.path')
postemi posts:create -c "Content" -s "2026-12-31T12:00:00Z" -m "$VIDEO_PATH" -i "tiktok-id"

Common Patterns

Pattern 1: Discover & Use Integration Tools

Most supported channels have no tools at all. Of the channels in the table at the top of this file, six expose a tool: Instagram (audioSearch), Discord (channels), Slack (channels), Pinterest (boards), WordPress (postTypes, categoriesList, tagsList) and Dev.to (tags, organizations). The others expose none: integrations:settings returns an empty tools array for them, and integrations:trigger on them returns 404 Tool not found.

Never guess a method name. Read the tools array from integrations:settings first; the methodName there is the only string integrations:trigger will accept.

bash

IG_ID=$(postemi integrations:list | jq -r '.[] | select(.identifier=="instagram") | .id')

# What can this channel actually do?
postemi integrations:settings "$IG_ID" | jq '.output.tools'
# [ { "methodName": "audioSearch", "description": "Search audio …", "dataSchema": [ … ] } ]

Instagram, find audio for a Reel:

bash

# Empty query returns trending audio. type is "music" (default) or "original_sound".
AUDIO=$(postemi integrations:trigger "$IG_ID" audioSearch -d '{"q":"lofi","type":"music"}')
AUDIO_ID=$(echo "$AUDIO" | jq -r '.output[0].id')

VIDEO=$(postemi upload reel.mp4 | jq -r '.path')
postemi posts:create \
  -c "Reel caption" \
  -s "2026-12-31T12:00:00Z" \
  --settings "{\"post_type\":\"post\",\"audio\":{\"id\":\"$AUDIO_ID\"}}" \
  -m "$VIDEO" \
  -i "$IG_ID"

Pattern 2: Upload Media Before Posting

bash

# Upload multiple files
VIDEO_RESULT=$(postemi upload video.mp4)
VIDEO_PATH=$(echo "$VIDEO_RESULT" | jq -r '.path')

THUMB_RESULT=$(postemi upload thumbnail.jpg)
THUMB_PATH=$(echo "$THUMB_RESULT" | jq -r '.path')

# Use in post
postemi posts:create \
  -c "Check out my video!" \
  -s "2026-12-31T12:00:00Z" \
  -m "$VIDEO_PATH" \
  -i "tiktok-id"

Pattern 3: Twitter Thread

bash

# Upload every image first (Rule 2)
INTRO=$(postemi upload intro.jpg | jq -r '.path')
P1=$(postemi upload point1.jpg | jq -r '.path')
P2=$(postemi upload point2.jpg | jq -r '.path')
OUTRO=$(postemi upload outro.jpg | jq -r '.path')

postemi posts:create \
  -c "🧵 Thread starter (1/4)" -m "$INTRO" \
  -c "Point one (2/4)" -m "$P1" \
  -c "Point two (3/4)" -m "$P2" \
  -c "Conclusion (4/4)" -m "$OUTRO" \
  -s "2026-12-31T12:00:00Z" \
  -d 5 \
  -i "$X_ID"
# -d is the delay between comments in MINUTES (here: 5 minutes)

Pattern 4: Multi-Platform Campaign (different content per channel)

JSON mode takes the API's real request body: type, date, shortLink, tags, and a posts array where each element names an integration, its value thread and its settings. There is no "integrations" key and no "provider" key; a full working file is examples/multi-platform-post.json.

bash

IMG=$(postemi upload sale.jpg | jq -r '.path')

cat > campaign.json << EOF
{
  "type": "schedule",
  "date": "2026-12-01T09:00:00Z",
  "shortLink": false,
  "tags": [],
  "posts": [
    {
      "integration": { "id": "<x-id>" },
      "value": [
        { "content": "Holiday sale! 🎄 20% off every plan. #sale", "image": [ { "id": "a", "path": "$IMG" } ] }
      ],
      "settings": { "who_can_reply_post": "everyone" }
    },
    {
      "integration": { "id": "<facebook-id>" },
      "value": [
        { "content": "Our holiday sale is live, 20% off every plan until the end of December. Details on the website!", "image": [ { "id": "b", "path": "$IMG" } ] }
      ],
      "settings": { "post_type": "post" }
    }
  ]
}
EOF

postemi posts:create --json campaign.json

Pattern 5: Validate Settings Before Posting

bash

#!/bin/bash

INTEGRATION_ID="$X_ID"
CONTENT="Your post content here"

# Get integration settings and extract max length
SETTINGS_JSON=$(postemi integrations:settings "$INTEGRATION_ID")
MAX_LENGTH=$(echo "$SETTINGS_JSON" | jq '.output.maxLength')

# Check character limit and truncate if needed
if [ ${#CONTENT} -gt "$MAX_LENGTH" ]; then
  echo "Content exceeds $MAX_LENGTH chars, truncating..."
  CONTENT="${CONTENT:0:$((MAX_LENGTH - 3))}..."
fi

# Create post with settings
postemi posts:create \
  -c "$CONTENT" \
  -s "2026-12-31T12:00:00Z" \
  --settings '{"key": "value"}' \
  -i "$INTEGRATION_ID"

Pattern 6: Batch Scheduling

bash

#!/bin/bash

# Schedule posts for the week
DATES=(
  "2026-02-14T09:00:00Z"
  "2026-02-15T09:00:00Z"
  "2026-02-16T09:00:00Z"
)

CONTENT=(
  "Monday motivation 💪"
  "Tuesday tips 💡"
  "Wednesday wisdom 🧠"
)

  # Rule 2: upload each file before passing to -m
  IMG=$(postemi upload "post-${i}.jpg" | jq -r '.path')
  postemi posts:create \
    -c "${CONTENT[$i]}" \
    -s "${DATES[$i]}" \
    -i "$X_ID" \
    -m "$IMG"
  echo "Scheduled: ${CONTENT[$i]} for ${DATES[$i]}"
done

Pattern 7: Error Handling & Retry

posts:create already retries for you: every run sends an Idempotency-Key (a new UUID per run) and, after a network failure or a 5xx, retries ONCE with the same key, so the server hands back the post it already made instead of making a second one. Running the command again is a NEW key and a NEW post. So never wrap posts:create in a retry loop; after a failure, look first:

bash

#!/bin/bash

CONTENT="Your post content"
INTEGRATION_ID="$X_ID"
DATE="2026-12-31T12:00:00Z"

if postemi posts:create -c "$CONTENT" -s "$DATE" -i "$INTEGRATION_ID"; then
  echo "Post created successfully"
else
  # Did it get through anyway? Check before running it again.
  postemi posts:list --startDate "$DATE" --endDate "$DATE"
fi

A 403 that names a missing permission is not retryable: the key is valid and lacks the scope. A 401 saying the workspace has no plan with API access is not retryable either: see billing:plans.

Technical Concepts

Integration Tools Workflow

Some integrations expose a tool for data that cannot be hard-coded. Among supported channels Instagram, Discord and Slack do. The workflow:

Check available tools - integrations:settings returns a tools array
Review tool schema - Each tool has methodName, description, and dataSchema
Trigger tool - Call integrations:trigger with required parameters
Use output - Tool returns data to use in post settings

Tools on supported channels, exhaustively:

Channel	Tools
Instagram (`instagram`)	`audioSearch`
Discord (`discord`)	`channels` (the server's channels; the `id` goes into `settings.channel`)
Slack (`slack`)	`channels` (the workspace's channels; the `id` goes into `settings.channel`)
X, Facebook, Threads, Bluesky, YouTube, LinkedIn, TikTok, Telegram	(none)

That is the whole list. There is no getPlaylists, no getCompanies, no getBoards, no getFlairs. Earlier versions of this file invented all four, and integrations:trigger answers 404 Tool not found for every one of them.

Provider Settings Structure

Platform-specific settings use a discriminator pattern with __type field:

json

{
  "posts": [
    {
      "provider": "youtube",
      "post": [{ "content": "Video description", "image": [...] }],
      "settings": {
        "__type": "youtube",
        "title": "Video title",
        "type": "public",
        "selfDeclaredMadeForKids": "no",
        "tags": [{ "value": "tech", "label": "Tech" }]
      }
    }
  ]
}

Pass settings directly:

bash

postemi posts:create -c "Content" -s "2026-12-31T12:00:00Z" --settings '{"title":"…","type":"public"}' -i "youtube-id"
# Backend automatically adds "__type" based on integration ID

Channels with no settings of their own (Threads and Bluesky) take an empty object. Do not invent fields for them.

You never have to write __type yourself. The server stamps it from the integration's provider before validating, overwriting whatever you sent. An example file carrying "__type": "EmptySettings" still works for that reason: it is being replaced, not accepted.

Two behaviours that surprise people

1. A key without posts:publish silently produces a draft. posts:create requires only posts:draft. If the key (or its owner's current role, a Contributor/DRAFTER) lacks posts:publish, the server coerces type to draft and creates a draft instead of refusing. It is not silent in the response: read back the type you got, do not assume the one you sent. If the user wanted it published, tell them the key cannot, rather than reporting success.

2. One X channel per post, always. A single post may not target two X channels, whatever the content. X's Developer Policy forbids substantially similar content from multiple accounts through one developer app, and the account at risk is Postemi's, shared by every customer. Split it into two posts. X alongside Facebook, Instagram, Threads, Bluesky, YouTube and the rest is unaffected. That combination is the entire point.

Comments and Threading

Posts can have comments (threads on Twitter/X, replies elsewhere). Each comment can have its own media:

bash

# Upload every file first (Rule 2)
I1=$(postemi upload image1.jpg | jq -r '.path')
I2=$(postemi upload image2.jpg | jq -r '.path')
CI=$(postemi upload comment-img.jpg | jq -r '.path')
A1=$(postemi upload another.jpg | jq -r '.path')
A2=$(postemi upload more.jpg | jq -r '.path')

postemi posts:create \
  -c "Main post" -m "$I1,$I2" \
  -c "Comment 1" -m "$CI" \
  -c "Comment 2" -m "$A1,$A2" \
  -s "2026-12-31T12:00:00Z" \
  -d 5 \  # Delay between comments in minutes
  -i "integration-id"

Internally creates (note: every URL is a Postemi-uploaded .path, not a raw filename):

json

{
  "posts": [{
    "value": [
      { "content": "Main post", "image": ["<uploaded image1>", "<uploaded image2>"] },
      { "content": "Comment 1", "image": ["<uploaded comment-img>"], "delay": 5 },
      { "content": "Comment 2", "image": ["<uploaded another>", "<uploaded more>"], "delay": 5 }
    ]
  }]
}

Date Handling

The contract: ALWAYS pass an explicit offset, or pass --timezone with an IANA name. The CLI never guesses a timezone. The server reads a naive datetime as UTC, which silently shifts a local "12:00" by the user's UTC offset. The CLI refuses ambiguity instead.

The two safe forms:

bash

-s "2026-12-31T12:00:00Z"                                  # explicit UTC
-s "2026-12-31 12:00" --timezone Europe/London           # wall-clock + IANA zone

How a date is resolved, in priority order:

Explicit offset in the string (Z, +01:00), used as written.
--timezone <IANA name> on posts:create / posts:list.
The saved config: postemi config:set timezone Europe/London (also offered interactively during postemi auth:login on a TTY).
None of the above and the date is naive → hard error, exit 1. The error names the fixes. Do not retry the same naive date; add a timezone.

Rules and behaviors:

Timezone values must be IANA names (Europe/London, UTC). Numeric offsets (+02:00, UTC+2, Etc/GMT+2) are rejected as timezone values. Never hand-compute DST; put an offset inside the date string only when you are certain of it, otherwise use the IANA name and let the CLI convert (DST-aware).
Whenever a timezone is applied (steps 2 to 4), the CLI echoes the resolved UTC instant on stderr: ℹ️ Interpreted "2026-12-24 18:00" as Europe/London (via --timezone) → 2026-12-24T18:00:00.000Z
A bare date ("2026-12-31") means midnight in the resolved timezone.
posts:list --startDate/--endDate accept the same shapes and the same --timezone flag; the defaults (30 days back / 30 days forward) never need a timezone.
postemi config:get / postemi config:get timezone shows what is saved; settings survive auth:logout.
postemi posts:find-slot <integration-id> returns {"date": "..."}, the next free slot on that channel's schedule; pass it straight back to posts:create -s.
-t now publishes immediately and needs no --date.

Media Upload Response

Upload returns JSON with path and metadata:

json

{
  "path": "https://…/uploads/2026/08/abc123.jpg",
  "size": 123456,
  "type": "image/jpeg"
}

Extract path for use in posts:

bash

RESULT=$(postemi upload image.jpg)
PATH=$(echo "$RESULT" | jq -r '.path')
postemi posts:create -c "Content" -s "2026-12-31T12:00:00Z" -m "$PATH" -i "integration-id"

JSON Mode vs CLI Flags

CLI flags - Quick posts:

bash

postemi posts:create -c "Content" -m "$(postemi upload img.jpg | jq -r '.path')" -s "2026-12-31T12:00:00Z" -i "$X_ID"

JSON mode - Complex posts with multiple platforms and settings:

bash

postemi posts:create --json post.json

JSON mode supports:

Multiple platforms with different content per platform
Complex provider-specific settings
Scheduled posts
Posts with many comments
Custom delay between comments

Platform-Specific Examples

Every field below is taken from the server's validation DTOs. A field that is not listed does not exist, and sending it is a 400.

X (Twitter): `x`

bash

postemi posts:create \
  -c "Tweet content" \
  -s "2026-12-31T12:00:00Z" \
  --settings '{"who_can_reply_post":"everyone"}' \
  -i "$X_ID"

who_can_reply_post is required: everyone | following | mentionedUsers | subscribers | verified. Optional: community (must match https://x.com/i/communities/<digits>), made_with_ai (bool), paid_partnership (bool).

Facebook: `facebook`

bash

IMG=$(postemi upload photo.jpg | jq -r '.path')
postemi posts:create \
  -c "Post text" \
  -s "2026-12-31T12:00:00Z" \
  --settings '{"post_type":"post"}' \
  -m "$IMG" \
  -i "$FB_ID"

All optional: post_type (post | story), url, text_format_preset_id (a background for a text-only post; Pages only, ~130 characters max).

Instagram: `instagram`

bash

IMG=$(postemi upload image.jpg | jq -r '.path')

# Feed post
postemi posts:create -c "Caption #hashtag" -s "2026-12-31T12:00:00Z" \
  --settings '{"post_type":"post"}' -m "$IMG" -i "$IG_ID"

# Story
STORY=$(postemi upload story.jpg | jq -r '.path')
postemi posts:create -c "" -s "2026-12-31T12:00:00Z" \
  --settings '{"post_type":"story"}' -m "$STORY" -i "$IG_ID"

post_type is required: post | story. Optional: collaborators (array of {label}), audio ({id, title?, artist?, image?, audio_volume?, video_volume?}; get the id from the audioSearch tool), is_trial_reel, graduation_strategy (MANUAL | SS_PERFORMANCE).

Threads (`threads`) and Bluesky (`bluesky`)

bash

postemi posts:create -c "Post text" -s "2026-12-31T12:00:00Z" -i "$THREADS_ID"

No provider settings. Omit --settings entirely.

What Postemi does NOT do

State these plainly rather than attempting a workaround.

No AI video generation. The /generate-video and /video/function routes were removed from the API entirely (2026-08-06). Do not tell a user Postemi can generate video, and do not call those routes: they 404.
No image or video generation of any kind. Media comes from files the user already has, via postemi upload.
No channel deletion. DELETE /integrations/:id was deliberately removed from the public API. Disconnecting a channel is a signed-in, admin action in the web app.
Nothing outside the channel table at the top of this file.

Optional skills: writing and growth

Two more Postemi skills are optional. They are not installed unless the user chose them:

Skill	What it adds	Install
writing (`postemi-writing` + `postemi-templates`)	post ideas, hooks, formatting, each network's writing rules, the composer's templates	`postemi skills add writing`
growth (`postemi-growth`)	choosing a niche, cadence per network, a 30-day plan, the weekly review	`postemi skills add growth`

bash

postemi skills list                          # core + optional, and where each is installed (JSON)
postemi skills add writing --json            # into every agent found (Claude Code, Codex, Cursor, Grok Build)
postemi skills add growth --agent claude --json
postemi skills remove growth --json

When the user asks for help writing posts or planning content and postemi skills list shows the skill as missing, offer it: say what it adds and ask. Run postemi skills add only after the user says yes; never install it silently. Pass --json (or run without a terminal) so the CLI asks no questions; a new agent session loads the skills.

Supporting Resources

examples/tiktok-video.json - TikTok with privacy

Common Gotchas

Not authenticated - Ask the user to run postemi auth:login and approve it in the browser
Invalid integration ID - Run integrations:list to get current IDs
Settings schema mismatch - Check integrations:settings for required fields
Media MUST be uploaded to Postemi first - ⚠️ CRITICAL (Rule 2): Every value passed to -m or to an image/media field in JSON mode must be a .path returned by postemi upload. Raw local filenames (image.jpg) and external URLs (https://...) will be rejected. TikTok, Instagram, YouTube and most other providers only accept Postemi-verified URLs. No exceptions: even a "quick test post" needs the upload step.
JSON escaping in shell - Use single quotes for JSON: --settings '{...}'
Date format - ISO 8601 with an explicit offset ("2026-12-31T12:00:00Z"), or a naive datetime plus --timezone <IANA name>. A naive datetime with no timezone configured is a hard error. Required except with -t now or --json.
Tool not found - Check available tools in integrations:settings output
Character limits - Each platform has different limits, check maxLength in settings
Required settings - YouTube requires title and type; X requires who_can_reply_post; Instagram requires post_type; TikTok requires privacy_level and content_posting_method; Discord and Slack require channel (an id from their channels tool). Threads, Bluesky, LinkedIn and Telegram require nothing.
Media MIME types - CLI auto-detects from file extension, ensure correct extension
Analytics returns {"missing": true} - The post was published but the platform didn't return a post ID. Run posts:missing <post-id> to get available content, then posts:connect <post-id> --release-id "<id>" to link it. Analytics will work after connecting.
