Welcome to the RingCentral Community

Hello dev community,

I am asking for a bit of help with something I am working on for one of my customers. I've been working on writing a Google Apps Script for Google Sheets that will pull the full detailed call log for an account log and dump it into a Google Sheet. The goal here is to use Sheets to enable some of the business users to do their own analysis of call log data directly inside of sheets without having to daily import CSV's. I am not a developer by any means, but I have been able to get quite a bit done with the help of Dave Hamel and Embbnux Ji and a few others from the RingCentral team.

Here's what I've got, I've gone through developer.ringcentral.com and created an App that uses only the Call Log API's and got it to pass the sandbox testing and it is now promoted for Production use. The Google App script I've got right now pulls only the specific user extension dumps the data into the Sheet (which is what Embbnux got working). The script needs to be tweaked to search for all extensions and then loop to pull the detailed call log for all users. For simplicity, I'd like it to just capture the last 30 days. Benjamin created a detailed call log export that pulls everything for an account as show in the link below.

I've used the Article here to help me get things rolling with the original Google Apps script. https://medium.com/ringcentral-developers/using-ringcentral-api-in-google-apps-script-a91c3367f37c

Below is the content of my Google Sheets Script that I have right now.

Any thoughts or recommendations on what I'd need to tweak to get this working and pull in the full call log?
