Errors

Read the response status and stable error code. See errors and rate limits for recovery. Refresh the resource before resolving a state or digest conflict.

Idempotency and retries

  • For throttling, honor Retry-After when present. Back off on retryable server failures.
  • Send a unique Idempotency-Key. An exact retry returns the stored result; reusing the key with a different request fails.
  • The request is accepted only when its credential, authority, case state, and resource preconditions are satisfied.
