I know there are numerous posts about this error, but I'm new to the box API and could use some help narrowing down the issue.
I've created a custom application of type Server Authentication (Client Credentials Grant). I also authorized this application in the admin console on the Server Authentication Apps tab.
I'm coding in C#. I have the .NET SDK installed in my project, and I'm using the .NET code sample from this page in the documentation: https://developer.box.com/guides/authentication/client-credentials/
When I plug in my client ID, secret, and username and run the code, I get this message:
The API returned an error [BadRequest] invalid_client - The client credentials are invalid at Box.V2.Extensions.BoxResponseExtensions.ParseResults[T](IBoxResponse`1 response, IBoxConverter converter) at Box.V2.CCGAuth.BoxCCGAuth.<CCGAuthPostAsync>d__8.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Box.V2.CCGAuth.BoxCCGAuth.<UserTokenAsync>d__7.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Runtime.CompilerServices.TaskAwaiter`1.GetResult() at MvcApplication.Controllers.HomeController.<Index>d__0.MoveNext() in M:\Domains\Rhythm_Box\MvcApplication\Controllers\HomeController.cs:line 19
If anyone from box support sees this, the client ID is 4ro5njohgyhnhzee8xluse1j334g7tiw
The account I was logged into when I created the application is the one named API User, if that makes a difference.
Thank you for any assistance.
A quick update: I created a new app with JWT authentication, and that seems to be working okay. I'm still curious what about the original approach was incorrect, but I'll keep going with the JWT version instead.
