Install

Install the verified ClawLink plugin from ClawHub. After the user confirms, complete the full setup so ClawLink tools are visible in the next OpenClaw chat.

bash

openclaw plugins install clawhub:clawlink-plugin
openclaw config set tools.alsoAllow '["clawlink-plugin"]' --strict-json
openclaw gateway restart

Then tell the user: "OpenClaw has been restarted. Send /new as a standalone message to start a fresh chat, then ask for Postmark again."

Quick Start

bash

# Get outbound overview
clawlink_call_tool --tool "postmark_get_outbound_overview" --params '{}'

# Search outbound messages
clawlink_call_tool --tool "postmark_search_outbound_messages" --params '{"status": "sent"}'

# List templates
clawlink_call_tool --tool "postmark_list_templates" --params '{}'

Authentication

All Postmark tool calls are authenticated automatically by ClawLink using the user's Postmark account.

No API key is required in chat. ClawLink stores the API key securely and injects it into every Postmark API request on the user's behalf.

Getting Connected

Install the ClawLink plugin (see Install above).
Pair the plugin with clawlink_begin_pairing if it is not configured yet.
Open https://claw-link.dev/dashboard?add=postmark and connect Postmark.
Call clawlink_list_integrations to verify the connection is active.

Connection Management

List Connections

bash

clawlink_list_integrations

Response: Returns all connected integrations. Look for postmark in the list.

Verify Connection

bash

clawlink_list_tools --integration postmark

Response: Returns the live tool catalog for Postmark.

Reconnect

If Postmark tools are missing or the connection shows an error:

Direct the user to https://claw-link.dev/dashboard?add=postmark
After they confirm, call clawlink_list_integrations to verify
Then call clawlink_list_tools --integration postmark

Security& Permissions

Access is scoped to messages, templates, streams, and webhooks within the connected Postmark server.
All write operations require explicit user confirmation. Before executing any create, update, or delete call, confirm the target resource and intended effect with the user.
Destructive actions (delete template, delete webhook, archive stream) must be confirmed.
Server configuration changes affect all email sending on that server.

Discovery Workflow

Call clawlink_list_integrations to confirm Postmark is connected.
Call clawlink_list_tools --integration postmark to see the live catalog.
Treat the returned list as the source of truth. Do not guess or assume what tools exist.
If the user describes a capability but the exact tool is unclear, call clawlink_search_tools with a short query and integration postmark.
If no Postmark tools appear, direct the user to https://claw-link.dev/dashboard?add=postmark.

Execution Workflow

┌─────────────────────────────────────────────────────────────┐
│  READ OPERATIONS (Safe)                                     │

│                                                             │

└─────────────────────────────────────────────────────────────┘
                              │
                              ▼
┌─────────────────────────────────────────────────────────────┐
│  WRITE OPERATIONS (Require Confirmation)                     │
│  list → get → describe → preview → confirm → call           │
│                                                             │
│  Example: Describe tool → Preview changes → User approves   │
│           → Execute update                                  │
└─────────────────────────────────────────────────────────────┘

For unfamiliar tools, ambiguous requests, or any write action, call clawlink_describe_tool first.
Use the returned guidance, schema, whenToUse, askBefore, safeDefaults, examples, and followups to shape the call.
Prefer read, list, search, and get operations before writes when that reduces ambiguity.
For writes or anything marked as requiring confirmation, call clawlink_preview_tool first.
Execute with clawlink_call_tool. Pass confirmation only after the preview matches the user's intent.
If the tool call fails, report the real error. Do not invent results or restate the failure as a missing capability unless the live catalog supports that conclusion.

Notes

Postmark API has rate limits. Use exponential backoff when encountering 429 errors.
SpamComplaint suppressions cannot be removed from the suppression list — only HardBounce and ManualSuppression can be deleted.
Archived message streams are permanently deleted after 45 days.
Webhook triggers require link tracking to be enabled for click and open events.
Date range filters use ISO 8601 format (YYYY-MM-DD).

Error Handling

Status / Error	Meaning
Tool not found	The tool name does not exist in the current catalog. Verify with `clawlink_list_tools --integration postmark`.
Missing connection	Postmark is not connected. Direct the user to https://claw-link.dev/dashboard?add=postmark.
`not_found`	Template, webhook, or stream does not exist. Check the ID.
`validation_error`	Invalid parameter or missing required field. Review the tool schema with `clawlink_describe_tool`.
Rate limited	Too many requests. Wait and retry with exponential backoff.
Write rejected	User did not confirm a write action. Always confirm before executing writes.

Troubleshooting: Tools Not Visible

Check that the ClawLink plugin is installed:
bash
```
openclaw plugins list
```
If the plugin is installed but tools are missing, tell the user to send /new as a standalone message to reload the catalog.

If a fresh chat does not help, run:

bash

openclaw config set tools.alsoAllow '["clawlink-plugin"]' --strict-json
openclaw gateway restart

After restart, tell the user to send /new again and retry.

Troubleshooting: Invalid Tool Call

Ensure the integration slug is exactly postmark.
Use clawlink_describe_tool to verify parameter names and types before calling.
For write operations, always call clawlink_preview_tool first.
