## Errors

| Code | HTTP | What it means |
|---|---|---|
| [`invalid_parameter`](/api/errors#invalid_parameter) | 400 | A value in your request does not have the expected format, for example a submission ID that is not a spec hash. Check the value against the field's description and try again. |
| [`no_acting_tenant`](/api/errors#no_acting_tenant) | 400 | Your request does not say which tenant you are acting for. Send your tenant ID in the `X-Tarsana-Tenant` header, or with `--as` on the command line. |
| [`isolation_refused`](/api/errors#isolation_refused) | 403 | This address belongs to a tenant ID you do not have access to. Check the tenant ID in the address and in your request header. |
| [`audit_unavailable`](/api/errors#audit_unavailable) | 503 | Your audit trail could not be written or read. If you made a change, it was carried out but is missing from the trail, so contact Tarsana support. |
| [`unauthenticated`](/api/errors#unauthenticated) | 401 | Your request has no credential, or one that Tarsana does not recognise. Sign in with `login`, or send a valid access token. |
| [`forbidden`](/api/errors#forbidden) | 403 | Your role does not allow this operation. The response names the roles that do; ask for a credential with one of them. |
| [`rate_limited`](/api/errors#rate_limited) | 429 | You sent too many requests in a short time. Wait for the number of seconds in `retry_after_seconds`, then try again. |
| [`surface_fault`](/api/errors#surface_fault) | 500 | Something went wrong on our side. Try again later, and contact Tarsana support if it keeps happening. |
