WhatsApp Coexistence Sync Errors

Practical handling guidance for common coexistence sync outcomes and webhook error events.

History not shared: handle history-sync declined outcomes and continue with contact/message echo workflows.

Unsupported webhook messages: gracefully surface fallback instructions and monitor auto-recovery behavior.

Offboard/reconnect events: automate status updates on account lifecycle webhooks and trigger re-onboarding guidance.

One-time sync limits: design retry-safe operations and clear operator runbooks for re-onboarding paths.
