Your payload would be: { "data": { "asset\_ids": ["your-asset-id"], "values": [{ "field\_definition\_id": "your-status-field-id", "value": ["status-uuid"] } ] } } I just tested this myself and confirmed this works.

             “values”: [{"field_definition_id": field_definition_id, "value": "my value”}]

}

```

i got the field\_definition\_id for my custom field (it doesn’t use the name) by calling this endpoint …

[https://api.frame.io/v4/accounts/{account\_id}/metadata/field\_definitions](https://api.frame.io/v4/accounts/%7Baccount_id%7D/metadata/field_definitions)

Hopefully this helps someone else out as well.
