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 @Joe.Catera 
I attached the image of the account name and client_name in some pictures below. Please help me check on the issue 401
Thanks

@Tran.Vinh, I spoke to our engineer again, and his last suggestion was to make sure your client secret was correct as well, even if that means generating a new one. If that doesn't work, please go to https://help.appdynamics.com/hc/en-us/requests and file a ticket, so our customer support team will look into it. I'd also make sure that the client name and account name don't have any trailing spaces. I hope regenerating a client secret helps, but if not, I'm sorry I couldn't help you.

@Joe.Catera 
It worked well after I got support from the customer support team.
Thank you so much.

Hi Tran.vinh, if you would like another example of how to get a token using an API secret, i'm doing the following on my rapport application: (https://github.com/open768/appdinc/blob/main/auth.php its in php, but hopefully you get the gist)

the querystring i use is

$oHttp->request_payload =
			"grant_type=client_credentials&" .
			"client_id=$app@$account&" .
			"client_secret=$api_secret";

with extra headers:

$oHttp->extra_headers = ["Content-Type" => "application/vnd.appd.cntrl+protobuf;v=1"];

 then do a GET request to the API for your controller  "/api/oauth/access_token"

this returns the access token to use for the API.
