unable to get token via api https://accountName.saas.appdynamics.com/controller/api/oauth/access_token

[Tran.Vinh]

I follow up on this doc to generate tokens via API but I didn't receive any response from the server.
https://docs.appdynamics.com/appd/4.5.x/en/extend-appdynamics/appdynamics-apis/api-clients#APIClient...
the curl like below:

curl -X POST -H "Content-Type: application/vnd.appd.cntrl+protobuf;v=1" "https://(accountName).saas.appdynamics.com/controller/api/oauth/access_token" -d 'grant_type=client_credentials&client_id=(username)@(accountName)&client_secret=(clientsecret)'
Please help me!

Hi, is this a production instance or a trial?

I just used your exact curl command, and updated with my values and it works. Don't see an issue with the Command.

I believe there is a limitation on using the API if using a trial, but if it is not a trial, you need to contact AppD Support to have a look at your controller to see what the issue is.

No it's not a trial. But it was working correctly so why would AppD devs ship out a breaking change without notifying us ? We haven't touched the controller in months
