I started the api geting started tutorial in the link below, however after an app is created, I can’t get a token using the given client key and client secret. I keep getting an “invalid_client” error. Can someone suggest how can I get authentication and a token?

Hey Terence,
Hey Terence,
There's a couple of reasons this could be happening for you. Either you're encoding in the wrong content type (it should be x-www-form-urlencoded, definitely not raw), or you're missing (or incorrect) key/value.
So check your content type is x-www-form-urlencoded.
And then make sure you set your client_id with the right value, client_secret with the right value and grant_type as client_credentials.
I hope this helps!
thanks,
David
