The backed service provider is OAuth protected with grant_type=client_credentials, can I know what assertions we need to configure for generating OAuth token in policy manager and use it for subsequent calls in Route Via assertion.
I'm looking for assertions which can make OAuth token call and store Authorization token in cache till it expires.
as of now we are doing this using route via HTTPS assertion and storing result in the cache and doing a lookup on the cache and if a cache is empty we are making a token call again. please let us know if we have any standard solution.
