I have a cron job running on my remote server. It checks for a condition and if satisfied it has to send a message on my cliq channel.  Now I was able to get the api endpoint url but then it requires auth token? How do I get one. I tried using developer console created a self client but it keeps showing no redirect uri if I added http://localhost it showed a problem occured try again later. How do I solve it as I just need a once time token which can be used by my service whenever it has to send a message.
