Feishu Doc Editor

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.
