As a client, in our organization, we use Client Credential flows for API to API calls. I’m running ServiceStack v.8.2.2. This version of AuthDtos uses AccessToken property, but the servers I call are using ServiceStack v6 and their authenticate route expects oauth_token.
It seems to me, I can no longer use ServiceStack.Authenticate from the v8.2.2 library. Instead, I have to build a POST request to my server manually calling their “/authenticate” route with a request model of oauth_token = {my Identity Server client token} and provider = “BearerTokenAuthProvider”
How is a newer client supposed to authenticate to older ServiceStack servers?
This question is a variation of “How to work around a breaking change in ServiceStack.AuthDtos removing oauth_token”
