application/json

{
  "data": {
    "id": "<string>",
    "name": "<string>",
    "width": 123,
    "type": "<string>",
    "config": {}

    "details": {}
  }
}

Leave id out: the platform mints an opaque fld_… and returns it. Every type carries its own config, and sending one that does not belong to the type is a validation error rather than a key nothing reads, call fields.types for the shapes. A computed field (lookup, rollup, formula, button) gets no column: it is derived at read time. A link creates its mirror field on the other table in the same write, and the two are deleted together.

Requires the schema:write scope. Operation fields.create. MCP tool fields_create. CLI, once published: gtable fields create.

Path parameters

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.
