A while back I put together an Airtable/Zapier/Google integration that extracted the distance between two addresses from Google Maps and popped it into Airtable. (As I recall, it took about a half-hour to slap together — and that included the time it took to figure out which Maps API I needed to use and to figure out how to get Zapier to talk to Maps.) The Zap configuration I gave in my reply should work fine for you, but instead of getting the
distance value from Google, get the
duration one instead.
This functionality requires a three-stage Zap and, thus, a paid Zapier account. However, when you register a new, free-level Zapier account, you’ll receive a two-week trial of the service’s premium features — more than enough to cover development, testing, and evaluation.
