      Hi Zendesk Team,
      I want to know how can I change the refresh_token expires_at. Currently it is by default 30 days.

      With the new Oauth updates mentioned here, will we be required to set a “refresh_token_expires_in”?  If the parameter is not included, will the access token have an expiration?

      I am facing same issue as mentioned in above comment.

      I have created a oAuth client with kind as confidential. I am using the /oauth/token API to get token by using client id, client secret, scope and grant as client_credentials. I am get the token, but when i use it with Ticket API, i get 401 "Couldn't authenticate you"

      However when i use the other token endpoint /api/v2/oauth/tokens, the access token recieved works fine with Ticket API or rather any other API.

      What am i missing ?

      I tried using client credentials flow with no luck. My client is confidential, I used client secret, no PKCE and the scope was “read”. The token was generated successfully with user_id null as I expected it. However, I can't do anything with it. No matter what endpoint I use, I always get 401 response. When I inspect the token, I see used_at to be the timestamp when I got the 401 response.

      Are there any restrictions on what I can use this token for?

      Are there any plans to add support for expiring access tokens? Having no expiration on access tokens negates a lot of the benefits of OAuth. It sounds like the overall approach to OAuth is being rethought, so wondering if expiration will be added as well.

      Zendesk recently announced support for OAuth2 client credentials flow. 

       

      https://support.zendesk.com/hc/en-us/articles/8983332483226-Announcing-support-for-OAuth-2-0-Client-Credentials-grant-type

       

      I am curious what “user” the client credential runs as? An issue we have had is that it has to run as a single user that has to be maintained an in worse case is deactivated etc. Can this new client credentials scheme operate without running as a particular named user in Zendesk?

      Now that all grant flows other than the authorization code grant flow have been deprecated, there is no longer a supported grant flow that is suitable for purely server-to-server communication (no user involved), correct?

       

      Are there any plans to add support for a grant flow more suitable for server-to-server communication such as the client credentials flow?

      I'm having the same issue with Amit.

       

      “Invalid Authorization Request”

      • Error: invalid_request

      • Description: “The request is missing a required parameter, includes an unsupported parameter or value, or is otherwise malformed.”

       

      https://{subdomain}.zendesk.com/oauth/authorizations/new?response_type=code&redirect_uri={URI}&client_id={UNIQUE_IDENTIFIER}&scope=read

       

       

      Anyone has any ideas?

      I’m trying to implement OAuth authentication, but I’m getting a generic error:

       

      “Invalid Authorization Request”

      • Error: invalid_request

      • Description: “The request is missing a required parameter, includes an unsupported parameter or value, or is otherwise malformed.”

       

      URL I’m using:

      https://{subdomain}.zendesk.com/oauth/authorizations/new?response_type=code&redirect_uri={URI}&client_id={UNIQUE_IDENTIFIER}&scope=read

       

      Can you help me debug this?

      I can get everything to work except the final step when calling “https://{subdomain}.zendesk.com/oauth/tokens”. This is returning a CORs error, and hence, we cannot move forward. All other endpoints work fine, and if I call the endpoint using CURL and the same parameters, I get a valid response. So this is purely a CORs issue. Can you help?
