Need help automating task - Approving new FB group members and adding them to a MailChimp list

Hey guys!

I’m trying to automate a process I do pretty routinely - Approving requests to join our private Facebook group and then adding their first name, last name, and email (their input as an answer to a question during the request) to a specific MailChimp list.

Facebook’s security is pretty tight so I’m having trouble finding a solution that I could easily set up. I may have to create a Chrome Extension to automate this, but before I do, any suggestions?

If you’ve solved this before, please let me know how and if not, any suggestions would be greatly appreciated!
