Airwallex API reference

Welcome to the Airwallex Client API.

The Client API is based on REST principles, offering a predictable and flexible integration experience for developers embedding financial flows into their applications.

The API suite offers a diverse range of products, including global business accounts, payment acceptance, spend management, and much more — all accessible on a single, unified API platform.

Sandbox accounts are available for testing integrations in a secure environment without live data before deploying to production. For more details, see Sandbox environment overview .

If you are building an application that connects to Airwallex business accounts using OAuth 2.0, see the Partner API API.
