API
Presents updates on REST API, Quickstart API, and SOAP API in 2025.Q4 product release.
REST API
For the detailed API documentation, see API Reference.
For a summary of REST API updates and documentation updates in the Zuora API Reference, see 2023 API Changelog.
Quickstart API
Zuora offers two sets of APIs for Billing, Payments, and Platform: the v1 API (the REST API) and the Quickstart API.
Zuora's v1 API provides complete coverage to our Zuora Billing, Payments, and Platform features. Zuora's Quickstart API represents a simplified programmatic experience and a subset of coverage for common e-commerce use cases. While often erroneously referred to as the v2 API, the Quickstart API is NOT a replacement for the v1 API and is no longer recommended for new integrations. See Quickstart API Reference.
Developers who need to access the full breadth of Zuora Billing, Payments, and Platform functionalities should use the v1 API, or our v3 SDKs (v1 for C# SDK) that are built on the v1 API.
SOAP API
Current WSDL version: 153
