Frequently Asked Questions

How do I start my first integration?

Register, create an API key in the console, and follow the signature examples in the docs; the free sandbox lets you finish a first integration in about ten minutes.

How do I verify webhooks?

Each callback carries an HMAC signature header — recompute it with your key per the documented algorithm and reject mismatches; failed deliveries retry automatically.
