Webhooks are HTTPS POST requests we send to your configured URL when relevant state changes (for example pay-in settled, payout failed, KYC updated).

​
What to implement

  • A public HTTPS endpoint that accepts POST JSON payloads.
  • Signature verification using the same secret material as API signing (see Webhooks for header names and examples).
  • Fast responses (acknowledge quickly; do heavy work asynchronously).

​
