Core concepts

  • Quotes lock pricing for 15 minutes.
  • Payins, payouts, and transfers are asynchronous.
  • Write requests use Idempotency-Key for safe retries.
  • Merchant resources are scoped to the API key that creates or accesses them.
  • Final payment status should be read from webhooks or follow-up GET requests.
