Status

Description

400

The request was rejected. `code` is `INVALID_INPUT`, and `errors` names the offending fields when the failure was a validation one.

401

Missing or invalid authentication. `code` is `UNAUTHORIZED`.

403

The caller is authenticated but not allowed to perform this operation. `code` is `FORBIDDEN` when the caller's role is insufficient, and `PLAN_LIMIT_REACHED` when the organization's plan is what stands in the way. The two are answered differently, so branch on the code rather than the status.

The resource does not exist, or the caller is not entitled to know that it does. `code` is `NOT_FOUND`.

413

The request body exceeds the 2 MB limit. `code` is `PAYLOAD_TOO_LARGE`.

415

The request body is not JSON, or carries a body without declaring a Content-Type. `code` is `UNSUPPORTED_MEDIA_TYPE`.

500

The request failed for a reason on our side. `code` is `INTERNAL_ERROR`. Quote `request_id` when reporting it.
