To submit REST API calls to ISE request must include Accept header – something like that:
“Accept: application/vnd.com.cisco.ise.identity.endpoint.1.0+xml”
Without it REST will return the error: The specified content-type is not supported. check the resource name in the request URI or the media type specified in the 'Accept' header.”
In the 2.1 REST API guide I cannot find such header for “External RESTful Services APIs for ANC”:
http://www.cisco.com/c/en/us/td/docs/security/ise/2-1/api_ref_guide/api_ref_book/ise_api_ref_ers2.html#83297
Can anyone help with this Accept header or give me idea how to reconstruct it?
