version so your integration keeps behaving the same way as the API evolves.
The version header
Send the version you built against in theNemu-Api-Version header.
Nemu-Api-Version header.
Discover the latest version
GET /api/version is public and needs no token. It reports the current major version, the
header name, the latest dated version, and every supported version.
Unsupported versions
If you send a version that is not in the supported list, the API rejects the request with400 and returns the versions it accepts.
Versions
Pin the version in the SDK
The SDK sends the latest version it knows about by default. Passapi_version to pin a
specific version, and read the versions from the exported ApiVersion enum.
ENDPOINTS map that describes every endpoint, the methods it
accepts, and the version it was introduced in.
What is versioned
Themajor version lives in the path as /api/v1. The dated version selects behavior
within that major version. The authorization endpoints, the token endpoint, and the version
endpoint are unversioned and do not take the header.
