API

Airwallex APIs offer a range of money movement capabilities designed for finance automation and embedded finance use cases. To determine the APIs that are suitable for your specific use case, explore our Product Docs. Our API Reference API groups API resources by capabilities to help you build bespoke financial solutions with flexibility and ease.

Authentication

To get started with Airwallex APIs, you need to obtain an access token, which will allow you to access all other API endpoints. You can obtain the access token by calling the Authentication API using your unique Client ID and API key retrieved from the Airwallex web app. See Quickstart with Postman.

API Versioning

Airwallex uses date-based versioning to introduce backwards incompatible API changes while ensuring that current integrations are not impacted. Clients can migrate to the new version when they are ready. See Versioning API.

Testing

Airwallex provides a demo environment to enable you to simulate transactions without moving real money. Contact your Airwallex Account Manager to request a demo account for your Airwallex account. For more information, see Demo environment overview.

Error handling

Airwallex uses standard HTTP status codes to indicate the success or failure of your API request. See Errors API.
