How to Use PHP on Cpanel to get Call Logs From All Users

I've been researching on how to access the logs for RingCentral for a while now and I'm having a bit of trouble. Essentially, I want to use a file on our web server to call the API and fetch all the records for every user (not just the owner account that I have the credentials set up on). Afterwards, I plan to store them in our database but I don't think I'll have issues there. From the link below, and other alternatives I've tried (Zapier), it appears that I need the username, password, and extension to get all this information collectively. Is there a way to get this information without requiring all users' passwords?
