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 overviewDocs.

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