# Save object sections

> Save object sections using an authenticated developer access key.

Required scopes: `objects:write`.

Send `{ "revision": 0, "sections": [] }` with the current revision and complete replacement layout. Returns `data.sections` and the incremented `data.revision`. Stale saves return 409; invalid definitions return 400. Record-scoped keys are rejected with 403. Removing a section retains saved entry values. See [payload examples and validation](/api-reference/record-sections).

See [authentication and rate limits](/api-reference/authentication).
