Keeping them separate makes everything more complicated: client developers have to know which service to use, and API services and gateways need some way to identify which Introspection endpoint needs to be used for each token. Each service will have OAuth 2.0 Introspection and Revocation endpoints, which will cause further confusion.</p> <p style="margin: 10px 0 0 0"> </p> </td>
