Not able to generate the OAuth 2.0 token based REST call, getting 500 Internal Server Error

[Mahendran_Pakki]

Hi,

I am using the SaaS controller for AppDynamics for testing the REST call.

I have to generate the token through REST call https://tataconsultancyservicesltd789.saas.appdynamics.com/controller/api/oauth/access_token

It was working till last 29/04/2020.

Now, I am not able to get the Token and gets 500 Internal Server Error.

I had this exact same issue and was informed that basic authentication is required in order to generate an OAuth 2.0 token as a workaround until the issue is resolved.

Hi @Martin.Herbert,

Can you please tell me what basic authentication is?

Hi @Atharva.Agashe,

I found this page on the AppD Docs page: https://docs.appdynamics.com/20.x/en/appdynamics-essentials/account-management/manage-users-and-grou...

You may need to alter the documentation based on your controller version for the most relevant info.

OAuth is generally managed using API Clients,

Not sure if you ask SaaS support to recheck the validity of token OR if there's any change in API CLient setting which changed the secret for your controller.
