API versioning
Versioning is specified via the Nex-Api-Version header. The current major version is v3.0.0. All requests must include the following header to be successful.
HeadersNex-Api-Version: v3.0.0
v3.0.0 and v20240412 are the same version
v3.0.0 was originally published under the date-based name v20240412, and you may still see that name in older material. The two names refer to the exact same version: the Nex-Api-Version header accepts either value, and both route to identical behavior. If your integration already sends Nex-Api-Version: v20240412, you do not need to change anything.
