# QR Ph Webhooks (Legacy)

> Understand the existing encrypted-JWE webhook contract for QR Ph payments

QR Ph webhooks notify your server when a QR Ph transaction succeeds or
is declined. This contract uses encrypted JWE request bodies, HTTP Basic
authentication for management operations, and the QR Ph encryption key.

<Warning>
  Do not use Payment Webhook `whsec_` secrets or `Webhook-*` signature headers
  with this integration. The two webhook contracts are not interchangeable.
</Warning>
