Webhooks overview


Avangate generates automatic notifications for transaction and subscription/license change events which it sends to a location on your server you control. You can perform backend tasks including provisioning, entitlement, customer and subscription lifecycle management and more by using  Avangate’s IPNs, LCNs, and API message services, on your server.


Use for the following events

Instant Payment Notifications (IPN)

Purchase and transactions events:

  • Authorized payments

  • Refunds
  • Chargebacks

License Change Notifications (LCN)

Webhook asynchronicity

Avangate’s webhooks (IPN and LCN) operate asynchronously.
