Problem with AccessTokenExpired Response when Sending Message from Server
When sending from a server using PHP I get an AccessTokenExpired response back. I am clocking the time difference between receiving and posting the request to send, and it is less the 1 second. When running the function I wrote to get a Token, I see a new token each time, so I don't believe there is anything wrong with the Registration Token request. Any idea what might be the problem?
