Sending & Receiving Payments

Environments

Sandbox mirrors production behavior and webhooks so you can test receiver resolution, quotes and funding instructions, settlement status changes, and full end‑to‑end flows without moving real funds.
Production uses live credentials and base URLs for real payments once you’re ready to launch.
