Authentication
This endpoint is public. It takes no credential and no organisation — it is what our own marketing site and AI answer engines read.
This endpoint takes no organisation id. Your key already identifies the organisation it belongs to, and the response is scoped to it.
Try it
Replace anything in angle brackets with your own values, and the key placeholder with a key from your dashboard.
curl -X POST https://api.zinndigital.com/v1/webhooks/paypalSigned in? The API console in your dashboard fills in your real organisation id and your own key, and runs the request against the live API so you can see the actual response. Open this endpoint in the API console
Details
**Unauthenticated by design** — PayPal holds no Zinn® credential, so its asymmetric transmission signature *is* the authentication, verified server-side against the configured webhook id via PayPal's `verify-webhook-signature` API over the raw body + `PAYPAL-*` transmission headers. This is the only path that turns a confirmed vaulted payment token into a chargeable mandate (`VAULT.PAYMENT-TOKEN.CREATED`) and the only path that settles an async capture (`PAYMENT.CAPTURE.COMPLETED`); neither may be asserted by a browser. Replays are expected and converge. An event type Zinn® does not handle is acknowledged with 200 (a non-2xx would make PayPal retry it).
Response
| Name | Type | Required | What it is |
|---|---|---|---|
status | string<handled, ignored, duplicate> | Yes | `handled` — acted on. `ignored` — a valid event of a type Zinn® does not consume. `duplicate` — already processed; Stripe may stop redelivering. |
