---

3. Prerequisites

3.1 Notion Integration Token (Internal Integration)

1. Go to https://www.notion.so/profile/integrations
2. Click "New integration"
3. Fill in:
4. Name: a descriptive label (e.g., "OpenClaw Bot")
5. Associated workspace: select your workspace
6. Type: Internal
7. Click Submit
8. Copy the Internal Integration Token — it starts with secret_

3.2 Share Pages / Databases with the Integration

By default, an integration can only see content it has been explicitly given access to.

1. Open the target page or database in Notion
2. Click the ··· (three-dot) menu in the top-right corner
3. Select "Add connections" or "Connect to"
4. Find and enable your integration by name
5. The integration can now access that page (and its children if appropriate)

3.3 Required Configuration

Store the token as an environment variable:

export NOTION_TOKEN="secret_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

Or set it in the OpenClaw gateway config under plugins.entries.notion.config.token.

Endpoint: GET https://api.notion.com/v1/blocks/{page_id}/children?page_size=100

Success response (200):

{
  "object": "list",
  "results": [
    {
      "id": "block-uuid-here",
      "type": "paragraph",
      "has_children": false,
      "paragraph": {
        "rich_text": [
          {
            "type": "text",
            "text": { "content": "Hello world", "link": null },

To check if a block has children and fetch them recursively:

{
  "id": "parent-block-id",
  "type": "toggle",
  "has_children": true,
  ...
}
# Follow up with: GET /v1/blocks/{parent-block-id}/children

}

With filter — Status equals "In Progress":

{
  "filter": {
    "property": "Status",
    "select": { "equals": "In Progress" }
  }
}

With filter — Due Date before a date:

{
  "filter": {
    "property": "Due Date",
    "date": { "before": "2024-12-31" }
  }
}

With filter — Title contains text:

{
  "filter": {
    "property": "Name",
    "title": { "contains": "launch" }
  }
}

With compound filter (AND):

{
  "filter": {
    "and": [

      { "property": "Status", "select": { "equals": "Done" } },
      { "property": "Status", "select": { "equals": "Cancelled" } }
    ]
  }
}

Sort by Due Date ascending:

{
  "sorts": [{ "property": "Due Date", "direction": "ascending" }]
}

Sort by multiple fields:

{
  "sorts": [
    { "property": "Status", "direction": "ascending" },
    { "property": "Priority", "direction": "ascending" }
  ]
}

Pagination — get next page:

{
  "start_cursor": "cursor-string-from-previous-response",
  "page_size": 100
}

Success response (200):

{
  "object": "list",
  "results": [
    {
      "object": "page",
      "id": "page-uuid",
      "properties": {

7. Installation Guide

Step 1 — Create a Notion Integration

1. Visit https://www.notion.so/profile/integrations
2. Click "Develop or manage integrations"
3. Click "New integration"
4. Fill in:
5. Name: OpenClaw (or any preferred name)
6. Workspace: select your workspace
7. Type: Internal
8. Click Submit
9. Copy and securely store the Internal Integration Token (starts with secret_)

Step 2 — Store the Token

Add to your shell profile:

export NOTION_TOKEN="secret_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

Or configure in the OpenClaw gateway config:

{
  "plugins": {
    "entries": {
      "notion": {
        "config": {
          "token": "secret_xxx"
        }
      }
    }
  }
}

Step 3 — Share Pages with the Integration

For the integration to access any page or database:

1. Open the page or database in Notion
2. Click ··· in the top-right corner
3. Select "Add connections"

4. Find your integration by name and enable it
5. Note: If a page has sub-pages, either share the top-level parent (children inherit access) or share each child individually

Step 4 — Verify Access

Test with a search call:

POST https://api.notion.com/v1/search
Authorization: Bearer {NOTION_TOKEN}
Notion-Version: 2022-06-28
Content-Type: application/json
Body: { "query": "test", "page_size": 1 }

• 200 response: Integration is working correctly
• 401 response: Token is invalid or malformed
• 403 response: Token is valid but the page is not shared with the integration

8. Caveats

8.1 Rate Limits

Plan	Requests per minute
Free	3 requests/second (~180/min)
Plus	7 requests/second (~420/min)
Business	15 requests/second (~900/min)

• On 429 response: Notion includes a Retry-After header. Wait that many seconds before retrying.
• Batching: When creating or updating many pages, add a 500ms–1s delay between calls.
• Pagination: Always check has_more before making follow-up requests to avoid infinite loops.

8.2 Block Structure

• The Notion API returns blocks as a flat list, even for nested content.
• Use the has_children: true flag on a block to detect children, then fetch them with GET /blocks/{id}/children.
• Block IDs are stable but change on page duplication. Always re-fetch IDs for newly duplicated pages.

8.3 Parent Page vs. Database

• parent: { "type": "page_id", "page_id": "..." } creates a standalone sub-page
• parent: { "type": "database_id", "database_id": "..." } creates a new row (entry) in that database
• When creating in a database, the properties must match the database schema exactly — unknown or mismatched properties cause a validation_error

8.4 Rich Text

• Rich text is always an array, even for a single string. Always wrap content in [{ ... }].
• Maximum length per rich_text array item is 2000 characters. For longer content, split into multiple blocks.

8.5 Archived Pages

• archived: true moves a page to trash; it remains accessible via API
• Archived pages do not appear in default search results
• Notion permanently deletes trash after 30 days
• To restore: PATCH /pages/{id} with archived: false

8.6 Database Schema Changes

• Changing a database's schema in the Notion UI (add/remove/rename properties) may break existing API calls that reference old property names
• Always call GET /databases/{id} first to fetch the current schema before creating or updating entries

8.7 ID Formats

• Notion page/database IDs are UUIDs with hyphens: abcd1234-abcd-1234-abcd-1234abcd1234
• In API paths, hyphens can be included or omitted: both work
• The 32-char raw ID (no hyphens) is used in internal Notion URLs

這個 Skill 質量不錯，功能涵蓋 Notion 的主要操作，文件寫得詳細清楚，新手也能看懂怎麼配置和使用。每個操作都有示例，出錯時也知道怎麼排查。不足的是文件只有文字說明，沒有配套的程式碼可以直接用，想快速上手還得自己寫程式碼對接。有幾個進階功能沒講到，比如批次操作和 block 的巢狀處理，稍微有點遺憾。總體來說，對於想整合 Notion 的開發者，這個 Skill 提供了足夠全面的參考，但落地使用還需要再完善一下。
