API and webhooks

Payments from your own code

Connect an app, create payment links from your backend, and let signed webhooks tell your app the moment a payment succeeds.

Read the docs See pricing

  • Links from an API call

    One request returns a link you can send or redirect to.

  • Signed webhooks

    Every event is signed, so your app can trust it, and retried if your server misses it.

  • A real sandbox

    Test the whole flow, success and failure, before you take real money.

How it works

  1. 1

    Create an app

    Get keys for sandbox and live in Apps and API.

  2. 2

    Create a link

    Call the API with an amount and a currency.

  3. 3

    Listen for the result

    Handle payment.successful in your webhook endpoint.

Questions

Is there a test mode?

Yes. Sandbox keys run the same flows without moving real money.
