Files

Upload a file for an attachment field

Two steps, on purpose.

POST/v1/tables/{tableId}/files

Request

curl --request POST \
  --url 'https://your-suite.gtable.app/your-app/v1/tables/<tableId>/files' \
  --header 'Authorization: Bearer <token>'

import json
import requests

url = "https://your-suite.gtable.app/your-app/v1/tables/<tableId>/files"
headers = {
  "Authorization": "Bearer <token>"
}

response = requests.request("POST", url, headers=headers)
print(response.json())

const response = await fetch("https://your-suite.gtable.app/your-app/v1/tables/<tableId>/files", {
  method: "POST",
  headers: {
    "Authorization": "Bearer <token>"
  },
});

const data = await response.json();
console.log(data);

application/json

{
  "data": {
    "id": "<string>",
    "name": "<string>",
    "size": 123.45,
    "mime": "<string>",
    "key": "<string>",
    "uploadedAt": "<string>",
    "width": 123.45,
    "height": 123.45
  }
}

{
  "error": {

    "message": "<string>",
    "details": {}
  }
}

This one takes the BYTES and answers with a descriptor: { id, name, size, mime, key, uploadedAt }. Writing that descriptor into an attachment field is an ordinary record write, so a file lands on a record through the same permission check, the same op log and the same undo as any other value. Send the file as multipart/form-data under file; recordId says which record it will belong to, so an upload that is never used can be swept. A descriptor you did not get from here is refused: its key names an R2 object, and inventing one would be naming somebody else’s bytes.

Requires the records:write scope. Operation files.upload. Not an MCP tool: a file is bytes and a tool call is JSON; upload with REST or the CLI. CLI, once published: gtable files upload.

Path parameters

Name	Type	Required	Description
`tableId`	string	yes

Headers

Name	Type	Required	Description
`Idempotency-Key`	string	no	Any unique string. Sending the same key with the same request again returns the first response (marked `Idempotency-Replayed: true`) instead of running it twice. Reusing it for a different request is refused with 409. Kept for 24 hours. Up to 255 characters.

Request body

Sent as multipart/form-data.

Field	Type	Required	Description
`file`	string	yes	The bytes.
`recordId`	string	yes	The record the file will be attached to, so an upload never attached can be swept.
