Webhooks let your system receive real-time updates from Alvys when business events occur. Instead of polling the API, Alvys sends an HTTPS POST request to your configured endpoint whenever a subscribed event is triggered. Webhooks are configured per Subsidiary. Each Subsidiary maintains its own set of webhook subscriptions. All deliveries:
  • Use HTTPS (TLS 1.2+)
  • Are signed using HMAC-SHA256
  • Follow an at-least-once delivery model
  • Are retried automatically on transient failure
  • Are disabled automatically after repeated delivery failures
To integrate successfully, your endpoint must verify signatures, handle retries safely, and implement idempotency.
