The /filter resource supports two custom OPTIONS requests, one for the resource as such and one for individual filter instances. The OPTIONS request allows you to check for the set of available operations that the currently authenticated user can perform on the /filter resource. Whether the user can perform an operation or not may depend on various factors, including the users authorizations to interact with this resource and the internal configuration of the process engine.
