Craft Connect

Read and write Craft documents via the Craft Connect API. Use when the user asks to create, read, update, or search Craft documents, manage tasks, write dail...

Craft Document Management

Operate on a Craft space via the Craft Connect REST API. Full CRUD on documents, blocks, folders, tasks, collections, and comments.

Requirements

• curl — used for all API requests
• CRAFT_API_URL — your Craft Connect API base URL (contains embedded link token for authentication)

Setup

1. Create a Craft Connect link in your Craft space (Settings → Connect → Create Link)
2. Copy the API base URL and store it in TOOLS.md under a Craft section:

CRAFT_API_URL=https://connect.craft.do/links/<LINK_ID>/api/v1

3. Read TOOLS.md before making any calls to retrieve the URL.

All calls use curl with -H "Content-Type: application/json" for writes and -H "Accept: application/json" for reads.

Important: URL-encode non-ASCII characters (e.g. Chinese) in query params.

Writing Content

Two methods: markdown (recommended) and blocks JSON.

Method 1: Markdown (Recommended)

Best for most content. Craft parses markdown and auto-generates correct block types, indentation levels, and list styles.

curl -s -X POST "$CRAFT_API_URL/blocks" \
  -H "Content-Type: application/json" \
  -d '{
    "markdown": "## Heading\n\nParagraph\n\n- bullet 1\n- bullet 2",
    "position": {"position": "end", "pageId": "<DOC_ID>"}
  }'

Method 2: Blocks JSON

Use when you need explicit control over color, font, textStyle, or other properties not expressible in plain markdown.

curl -s -X POST "$CRAFT_API_URL/blocks" \
  -H "Content-Type: application/json" \
  -d '{
    "blocks": [
      {"type": "text", "textStyle": "h2", "markdown": "## Title"},
      {"type": "text", "color": "#00A3CB", "markdown": "<callout>💡 Info</callout>"}
    ],
    "position": {"position": "end", "pageId": "<DOC_ID>"}
  }'

Position Options

Position	Syntax
Append to document	{"position": "end", "pageId": "<DOC_ID>"}
Prepend to document	{"position": "start", "pageId": "<DOC_ID>"}
After a specific block	{"position": "after", "siblingId": "<BLOCK_ID>"}
Before a specific block	{"position": "before", "siblingId": "<BLOCK_ID>"}
Append to daily note	{"position": "end", "date": "today"}

Updating & Deleting Blocks

# Update (only provided fields change; others preserved)
curl -s -X PUT "$CRAFT_API_URL/blocks" \
  -H "Content-Type: application/json" \
  -d '{"blocks": [{"id": "<BLOCK_ID>", "markdown": "Updated", "font": "serif"}]}'

# Delete blocks (permanent!)
curl -s -X DELETE "$CRAFT_API_URL/blocks" \
  -H "Content-Type: application/json" \
  -d '{"blockIds": ["<ID1>", "<ID2>"]}'

# Move blocks between documents
curl -s -X PUT "$CRAFT_API_URL/blocks/move" \
  -H "Content-Type: application/json" \
  -d '{"blockIds": ["<ID>"], "position": {"position": "end", "pageId": "<DOC_ID>"}}'

Tasks

# List tasks (scopes: inbox, active, upcoming, logbook, document)
curl -s "$CRAFT_API_URL/tasks?scope=active"
curl -s "$CRAFT_API_URL/tasks?scope=document&documentId=<DOC_ID>"

# Create task in inbox
curl -s -X POST "$CRAFT_API_URL/tasks" \
  -H "Content-Type: application/json" \
  -d '{"tasks": [{"markdown": "Task text", "taskInfo": {"scheduleDate": "tomorrow"}, "location": {"type": "inbox"}}]}'

# Create task in daily note
curl -s -X POST "$CRAFT_API_URL/tasks" \
  -H "Content-Type: application/json" \
  -d '{"tasks": [{"markdown": "Task", "taskInfo": {"scheduleDate": "2025-01-20", "deadlineDate": "2025-01-22"}, "location": {"type": "dailyNote", "date": "today"}}]}'

# Create task in a document
curl -s -X POST "$CRAFT_API_URL/tasks" \
  -H "Content-Type: application/json" \

  -H "Content-Type: application/json" \
  -d '{"tasksToUpdate": [{"id": "<TASK_ID>", "taskInfo": {"state": "done"}}]}'

# Delete task
curl -s -X DELETE "$CRAFT_API_URL/tasks" \
  -H "Content-Type: application/json" \
  -d '{"idsToDelete": ["<TASK_ID>"]}'

Collections (Structured Databases)

Collections are like Notion databases — structured tables with typed columns.

# List all collections
curl -s "$CRAFT_API_URL/collections"

# Create collection in a document
curl -s -X POST "$CRAFT_API_URL/collections" \
  -H "Content-Type: application/json" \
  -d '{
    "schema": {
      "name": "Tasks",
      "contentPropDetails": {"name": "Title"},
      "properties": [
        {"name": "Status", "type": "singleSelect", "options": [{"name": "Todo"}, {"name": "In Progress"}, {"name": "Done"}]},
        {"name": "Priority", "type": "singleSelect", "options": [{"name": "High"}, {"name": "Medium"}, {"name": "Low"}]},
        {"name": "Due Date", "type": "date"}
      ]
    },
    "position": {"position": "end", "pageId": "<DOC_ID>"}
  }'

# Get schema (use json-schema-items format to learn the property keys!)
curl -s "$CRAFT_API_URL/collections/<COL_ID>/schema?format=json-schema-items"
# ⚠️ IMPORTANT: schema returns auto-generated keys like "", "_2", "_3", "_4"
# You MUST read the schema first to know the correct keys for items

# Get items
curl -s "$CRAFT_API_URL/collections/<COL_ID>/items"

# Add items (use schema keys, NOT "title"!)
# First GET the schema to find the contentProp key (e.g. "_4" for title)
curl -s -X POST "$CRAFT_API_URL/collections/<COL_ID>/items" \
  -H "Content-Type: application/json" \
  -d '{"items": [{"<CONTENT_KEY>": "Item Title", "properties": {"<STATUS_KEY>": "Todo", "<PRIORITY_KEY>": "High"}}]}'

# Update items
curl -s -X PUT "$CRAFT_API_URL/collections/<COL_ID>/items" \
  -H "Content-Type: application/json" \
  -d '{"itemsToUpdate": [{"id": "<ITEM_ID>", "properties": {"<STATUS_KEY>": "Done"}}]}'

# Delete items
curl -s -X DELETE "$CRAFT_API_URL/collections/<COL_ID>/items" \
  -H "Content-Type: application/json" \
  -d '{"idsToDelete": ["<ITEM_ID>"]}'

# Update schema (replaces entirely — include ALL fields you want to keep)
curl -s -X PUT "$CRAFT_API_URL/collections/<COL_ID>/schema" \
  -H "Content-Type: application/json" \
  -d '{"schema": { ... }}'

Block Types & Formatting

Headings

# H1 Title          → textStyle: "h1"
## H2 Subtitle      → textStyle: "h2"
### H3 Heading      → textStyle: "h3"
#### H4 Strong      → textStyle: "h4"

Inline Styles

**bold**, *italic*, ~strikethrough~, `inline code`
[link text](https://url)
$(a+b)^2$                    ← inline equation

Highlights (9 solid + 5 gradient)

<highlight color="COLOR">text</highlight>

Solid: yellow, blue, red, green, purple, pink, mint, cyan, gray Gradient: gradient-blue, gradient-purple, gradient-red, gradient-yellow, gradient-brown

Lists

- bullet item           → listStyle: "bullet"
1. numbered item        → listStyle: "numbered"
- [ ] todo task         → listStyle: "task", taskInfo.state: "todo"
- [x] completed task    → listStyle: "task", taskInfo.state: "done"
+ toggle (collapsible)  → listStyle: "toggle"

Toggle (Collapsible) Lists — CRITICAL

Children MUST be indented 2 spaces to nest inside a toggle:

+ Parent toggle
  - Child 1 (hidden when collapsed)
  - Child 2
  + Nested toggle
    - Deep child

Use markdown mode only. indentationLevel in blocks JSON is silently ignored on insert.

Blockquote

> Quoted text

Produces block with decorations: ["quote"].

Dividers / Lines

Blocks JSON with lineStyle:

{"type": "line", "lineStyle": "extraLight", "markdown": "***"}
{"type": "line", "lineStyle": "light", "markdown": "****"}
{"type": "line", "lineStyle": "regular", "markdown": "*****"}
{"type": "line", "lineStyle": "strong", "markdown": "******"}

Markdown mode: --- produces extraLight by default.

Code Blocks

Markdown mode:

```python
def hello():
    print("Hello")
```

Blocks JSON (requires rawCode!):

{"type": "code", "language": "python", "rawCode": "def hello():\n    print('Hello')", "markdown": "```python\ndef hello():\n    print('Hello')\n```"}

Math Formula (TeX)

{"type": "code", "language": "math_formula", "rawCode": "x = \\frac{-b \\pm \\sqrt{b^2 - 4ac}}{2a}", "markdown": "```math_formula\nx = \\frac{-b \\pm \\sqrt{b^2 - 4ac}}{2a}\n```"}

Inline equation in markdown: $(a+b)^2 = a^2 + 2ab + b^2$

Tables

Markdown mode:

| Col A | Col B |
| --- | --- |
| val 1 | val 2 |

Images

Blocks JSON:

{"type": "image", "url": "https://example.com/photo.jpg", "markdown": "![Alt](https://example.com/photo.jpg)"}

Craft re-hosts the image and returns a https://r.craft.do/ URL.

Rich URL (Link Preview)

{"type": "richUrl", "url": "https://www.youtube.com/watch?v=..."}

Page / Card (Sub-pages)

{"type": "page", "textStyle": "page", "markdown": "Sub-page Title"}
{"type": "page", "textStyle": "card", "markdown": "Card Title"}

Then insert content inside using the returned page ID as pageId.

Callouts (Colored Blocks)

Require blocks JSON with color:

{"type": "text", "color": "#00A3CB", "markdown": "<callout>💡 Info</callout>"}

Common colors: #00A3CB (blue/info), #FF3B30 (red/warning), #34C759 (green/success), #FF9500 (orange/caution), #9862E8 (purple), #003382 (deep blue), #006744 (deep green), #864d00 (brown), #ef052a (bright red), #9ea4aa (gray).

Callouts support inline styles inside: <callout>**bold** and <highlight color="yellow">highlight</highlight></callout>

Fonts

Set via font in blocks JSON: (default), serif, mono, rounded.

Caption

{"type": "text", "textStyle": "caption", "markdown": "<caption>Small annotation</caption>"}

Task Blocks in Documents

{"type": "text", "listStyle": "task", "taskInfo": {"state": "todo"}, "markdown": "- [ ] Task"}

States: todo, done, canceled — NOT "completed".

Combination Example

{
  "type": "text",
  "font": "rounded",
  "textStyle": "h3",
  "color": "#9862E8",
  "markdown": "<callout>### ✨ Purple rounded heading callout</callout>"
}

Choosing Insert Method

Need	Use	Why
Text, lists, headings	Markdown	Clean, auto-detects types
Toggle lists with children	Markdown	Only way to get indentation right
Code blocks, tables	Either	Markdown is simpler; JSON needs rawCode
Colored callouts	Blocks JSON	Need color property
Custom fonts	Blocks JSON	Need font property
Captions	Blocks JSON	Need textStyle: "caption"
Images, richUrl, pages	Blocks JSON	Need type field
Line styles	Blocks JSON	Need lineStyle
Math formulas	Blocks JSON	Need language: "math_formula" + rawCode
Mixed content	Split calls	Combine markdown + blocks JSON

Gotchas & Lessons Learned

1. Toggle indentation: markdown mode with 2-space indent is the only way. indentationLevel in blocks JSON is silently ignored on insert.

2. Task state values: todo | done | canceled. NOT completed.

3. Position after/before: use siblingId (not blockId).

4. Position end/start: use pageId or date.

5. Code blocks in JSON mode: require rawCode field. Without it you get a validation error.

6. Collection item keys: the API docs say title but the real field name is the auto-generated contentProp key from the schema (e.g. _4). Always GET /collections/<id>/schema?format=json-schema-items first to discover the correct keys.

7. URL-encode search terms: Chinese and special characters in query params must be URL-encoded or curl returns 400.

8. Accept header: use application/json for reads. text/markdown may 502.

9. Document delete is soft: goes to trash, restorable via move. Block delete is permanent.

10. Large inserts: one POST can insert many blocks. Prefer fewer larger writes to avoid rate limits.

11. Image re-hosting: Craft downloads external images and re-hosts them at https://r.craft.do/. Your original URL is replaced.

12. Collections are experimental: the API may change. Always read the schema before writing items.
