I'm quite new to this but I've been trying to set up Twilio Frontline for my work. It's asking me for some CRM Callback URLs in order to be able to view contacts on the phone app. Here's some documentation of what they're asking for: https://www.twilio.com/docs/frontline/my-customers.
I'm just wondering how to do this for HubSpot as from what I'm seeing, I'd need to set up my own sample database and add contacts manually. Can anyone help me?
