ADFS Token Validation

Question

Hi,

We hosted an api (API) which will receive request from client application(APP). The client app will send the request along with ADFS token in header (bearer). I need to validate the token which is issued by the same issuer or not. If it is valid I need to proceed with further process else return an error.

Please let me know how can I implement this and appreciate if there is any code sample available.

Thank you
