Zendesk sync fails when an OAuth token expires during a request
1 source thread · first seen 2026-10
Summary
A request that is in flight when the access token expires receives `invalid_token`, which the connector treats as a fatal configuration error instead of refreshing and retrying. This causes recurring sync failures; a later sync or orchestrator retry succeeds after refreshing the token.
- Workaround
- The next sync or an immediate orchestrator retry refreshes the token and succeeds.
