| ------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| 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. |
| 404    | 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.                                                                                                                                                                                        |
