Feishu Document Editor Skill

This skill provides comprehensive guidance for creating and editing Feishu documents using the Feishu OpenAPI.

Prerequisites

1. App Creation and Configuration

Create enterprise self-built app: Login to Feishu Open Platform, create an app and add "Bot" capability.

Apply for API permissions: In "Permission Management", apply for the following permissions:

• Document editing: docx:document:write_only
• Document viewing: docx:document:readonly

Publish app: Submit version and publish, ensuring the app coverage includes target users/departments.

2. Get Access Token

Call the self-built app get tenant_access_token interface:

curl -X POST https://open.feishu.cn/open-apis/auth/v3/tenant_access_token/internal \
  -H "Content-Type: application/json" \
  -d '{"app_id": "your_app_id", "app_secret": "your_app_secret"}'

Response example:

{
  "code": 0,
  "tenant_access_token": "t-xxx",
  "expire": 7200
}

Core Operations

Extract Document ID

Get document_id from document URL:

Example URL: https://bigdatacenter.feishu.cn/docx/HpK2dtGu9omhMAxV12zcB6i7ngd

document_id = HpK2dtGu9omhMAxV12zcB6i7ngd

Grant App Document Permission

Manually add collaborator:

• Open document in Feishu client → Click "..." in top right → "More" → "Add document app"
• Search and add your app, grant "Can edit" permission.

Write Text Content

Interface: Create Block

• Path parameters: document_id = document ID, block_id = document ID (root node is the document itself)

• Request headers:

  Authorization: Bearer {tenant_access_token}
  Content-Type: application/json
  

• Request body example (write "hello"):

  {
    "index": -1,
    "children": [
      {
        "block_type": 2,
        "text": {
          "elements": [
            {
              "text_run": {
                "content": "hello"
              }
            }
          ]
        }
      }
    ]
  }
  

Read Document Content

Interface: Get Document Plain Text

curl -X GET "https://open.feishu.cn/open-apis/docx/v1/documents/{document_id}/plaintext" \
  -H "Authorization: Bearer {tenant_access_token}"

Response example:

{
  "code": 0,
  "data": {
    "content": "Document text content here"
  }
}

Common Issues

1. Permission Error (403 Forbidden)

• Diagnosis: App not added as document collaborator, or tenant_access_token is invalid.
• Solution: Re-add app as collaborator, or re-get tenant_access_token.

2. Missing Access Token (99991661)

• Diagnosis: Request header does not carry Authorization: Bearer {token}.
• Solution: Ensure tenant_access_token is correctly added to request header.

3. Document Not Found (404 Not Found)

• Diagnosis: document_id is incorrect or document has been deleted.
• Solution: Re-extract document_id from document URL.

Reference Documentation

• Create Block Interface
• Get Document Plain Text Interface
• Permission Configuration Guide

Through the above steps, you can achieve editing Feishu documents via API, supporting add/delete/modify/query operations for multiple content types including text, tables, and images.
