When submitting a request to the REST API, specify the version of the API being used. The version number is a path parameter in each resource URI. The desired API version is substituted into the request URI as follows:
Changes to the API are tracked with a version number (version major) and a revision number (version minor).
The version number indicates forwards and backwards compatibility.
The revision number within the version describes features added to the API that will not negatively affect current functionality.
Only the version number is referenced as part of the request. The revision number simply tracks incremental enhancements to the API.
When a new version of the API is released, update the scripts and code as soon as possible.
To find out what version of the API is available from a given server, submit a GET request to the base API URI. For example, in a web browser, browse to:
The system will return the version:
The API was originally intended for internal use or for just a few customers. In those early days, API versioning was different. If working with legacy scripts, this older functionality can be maintained. For example, if scripts were written before v2 and have nondefault system configuration properties for api.prefix and api.rewrite on the server, the …/api/ URI lists the resources and does not provide version information.
