Feishu Doc

Replaces entire document with markdown content. Supports: headings, lists, code blocks, quotes, links, images (![](url) auto-uploaded), bold/italic/strikethrough.

Limitation: Markdown tables are NOT supported.

Append Content

{ "action": "append", "doc_token": "ABC123def", "content": "Additional content" }

Appends markdown to end of document.

Create Document

{ "action": "create", "title": "New Document", "owner_open_id": "ou_xxx" }

With folder:

{
  "action": "create",
  "title": "New Document",
  "folder_token": "fldcnXXX",
  "owner_open_id": "ou_xxx"
}

Important: Always pass owner_open_id with the requesting user's open_id (from inbound metadata sender_id) so the user automatically gets full_access permission on the created document. Without this, only the bot app has access.

List Blocks

{ "action": "list_blocks", "doc_token": "ABC123def" }

Returns full block data including tables, images. Use this to read structured content.

Get Single Block

{ "action": "get_block", "doc_token": "ABC123def", "block_id": "doxcnXXX" }

Update Block Text

{
  "action": "update_block",
  "doc_token": "ABC123def",
  "block_id": "doxcnXXX",
  "content": "New text"
}

Delete Block

{ "action": "delete_block", "doc_token": "ABC123def", "block_id": "doxcnXXX" }

Create Table (Docx Table Block)

{
  "action": "create_table",
  "doc_token": "ABC123def",
  "row_size": 2,
  "column_size": 2,
  "column_width": [200, 200]
}

Optional: parent_block_id to insert under a specific block.

Write Table Cells

{
  "action": "write_table_cells",
  "doc_token": "ABC123def",
  "table_block_id": "doxcnTABLE",
  "values": [
    ["A1", "B1"],
    ["A2", "B2"]
  ]
}

Create Table With Values (One-step)

{
  "action": "create_table_with_values",
  "doc_token": "ABC123def",
  "row_size": 2,
  "column_size": 2,
  "column_width": [200, 200],
  "values": [
    ["A1", "B1"],
    ["A2", "B2"]
  ]
}

Optional: parent_block_id to insert under a specific block.

Upload Image to Docx (from URL or local file)

{
  "action": "upload_image",
  "doc_token": "ABC123def",
  "url": "https://example.com/image.png"
}

Or local path with position control:

{
  "action": "upload_image",
  "doc_token": "ABC123def",
  "file_path": "/tmp/image.png",
  "parent_block_id": "doxcnParent",
  "index": 5
}

Optional index (0-based) inserts the image at a specific position among sibling blocks. Omit to append at end.

Note: Image display size is determined by the uploaded image's pixel dimensions. For small images (e.g. 480x270 GIFs), scale to 800px+ width before uploading to ensure proper display.

Upload File Attachment to Docx (from URL or local file)

{
  "action": "upload_file",
  "doc_token": "ABC123def",
  "url": "https://example.com/report.pdf"

{
  "action": "upload_file",
  "doc_token": "ABC123def",
  "file_path": "/tmp/report.pdf",
  "filename": "Q1-report.pdf"
}

Rules:

• exactly one of url / file_path
• optional filename override
• optional parent_block_id

Reading Workflow

1. Start with action: "read" - get plain text + statistics
2. Check block_types in response for Table, Image, Code, etc.
3. If structured content exists, use action: "list_blocks" for full data
