Hi there, I am quite new to web development. I'm learning how to get a token to talk to REST API but I can't figure out how. I read to the step that said: "

To obtain a token, follow these steps:

1. Login to your Engage portal and click on the "Admin" menu located in the top, horizontal menu." - Now when I log in https://engage.ringcentral.com/ I get an error "

   HTTP Status 400 – Bad Request"

2. I used the same login credential as the one I usually login with ring central.

Please advise. Thank you.
