# Create an object

POST https://api.cloudraker.com/spaces/{spaceId}/objects/{definitionId}
Content-Type: application/json

Creates one object of a definition within a space. Authorization: requires `space:contribute` on `:spaceId` — lacking it gives **403** (no `space:read` → 404). Body: `{ data, fieldMeta? }` — `data` is field values keyed by field key (validated against the definition via JSON Schema; defaults applied); optional `fieldMeta` accepts only `source`/`locked` per key. A `unique`-field collision returns 409 `duplicate_value` (with `fieldKey`); invalid data → 422 `validation_failed`. Returns 201 with `{ object }`.
