{: #api-versioning}
API requests require a version path parameter that takes the date in the format /toolchain/{version}/{endpoint}, or /pipeline/{version}/{endpoint}, where endpoint represents any listed endpoint in the corresponding API documentation. The only version which is currently supported is v2.
When the API is changed in a way that is not compatible with previous versions, a new major version is released. To take advantage of the changes in a new version, change the value of the version parameter to the new version.
