400 BadRequest - C# Client - RestClient call to Authorize

Have you checked the following similar reference:

https://community.ringcentral.com/questions/968/c-authorization-400-bad-request.html

https://community.ringcentral.com/questions/1347/oauthtoken-server-400-error.html

https://community.ringcentral.com/questions/1512/cannot-establish-connection-with-ring-central-serv.html

Hope that helps

All 3 of those references are passing in username/password where I'm passing in the return code sent to me (via redirect uri) once the user accepts the use of the apps requested permissions. Don't know if that makes any difference. The one note that I thought may help was about disabling auto-refresh. I added the following command "rc.AutoRefreshToken = false" prior to making the call to authorize. Still seeing the same error.

Ok. Is there anything else I can provide here to help resolve this issue? I'm not getting any worthwhile detailed info on this error. Here's what the error says...

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.



Exception Details: Flurl.Http.FlurlHttpException: Call failed with status code 400 (Bad Request): POST https://platform.devtest.ringcentral.com/restapi/oauth/token

Again, I'm using the C# RestClient to call "Authorize" and I'm passing in the code returned to me by RingCentral along with a redirect-url.

Here's a more palatable stack trace. Sorry for the mess in the original post...

Follow this quick start sample https://developers.ringcentral.com/guide/authentication/quick-start.

You don't call the .authorize() that way. Where did you get that idea or instruction?

TokenInfo tokenInfo = await rc.Authorize(code, productDomain + ringCentralOauthTokenCallbackUrl);

Whether I call Authorize with or without the TokenInfo assignment (as in the quick-start guide that you point to) I still get the same, useless, error. Very frustrating. I'm not using dotnet core either (as the guide does)

Ok. Just to follow up. Turns out the reason for the "Bad Request" is because the url I specified in the call to "Authorize" was not the same as the one specified in the call to "AuthorizeUrl". Am a little surprised because both url's are registered in my sandbox application. In any event, I'm now beyond that hurdle. Thanks for all the various hints.
