Hi Paul,

that's not what I meant. The Client should know which tokens should be one time usage based on the API description. The authz server must not return expires_in because this would not make any sense in this case.


Paul Madsen <> schrieb: 

Hi Torsten, yes the use case in question is payment-based as well. 

Your suggestion for the client to infer one-time usage from a missing expires_in contradicts the general consensus of this thread does it not?

Hi, isn't one-time semantics typically associated with certain requests on certain resources/resource types. I therefore would assume the client to know which tokens to use one-time only. The authz server should not return an expires_in paramter. We for example use one time access tokens for payment transactions. What would such an extension specify? regards, Torsten.
