Examples
Avoid a duplicate-call retry after a network timeout
An outbound request times out after submission. Before retrying, look up the request correlation or call identifier to determine whether Retell already created the call. If state is unknown, hold the retry and escalate with the redacted request metadata; sending a second request can contact the same person twice. Add bounded retries only where the operation is explicitly idempotent and monitor the duplicate-call rate after the change.
