CaaS API Reference

Every Rach CaaS endpoint, with live “try it” and code samples.

This reference is generated from the Rach CaaS OpenAPI specification. CaaS is a separate product with its own base URL and keys — see the CaaS overview.

Authentication

Every B2B endpoint uses your CaaS API key in the X-API-Key header, prefixed rach_sk_live_ / rach_sk_test_.

CaaS keys are separate from your Payments keys and are not interchangeable. See Get your API keys.
