The video for this guide is coming soon. The written steps below cover everything.

What you get

Customer emails land in your inbox and on their timeline; replies and one-to-one emails go out from your own Gmail in the same thread. Bookings check your Google Calendar for busy times, land on it with a Meet link, and move or disappear when the customer changes them. Customers can sign up with Google.

Steps

In Google Cloud Console, create a project and enable the Gmail API and the Google Calendar API.
Set up the consent screen. Choose Internal on Google Workspace; on personal Gmail, choose External and add yourself as a test user.
Create an OAuth client (Web application) with both redirect URLs: https://YOUR_URL/api/google/callback and https://YOUR_URL/api/auth/google/callback.
Set GOOGLE_CLIENT_ID and GOOGLE_CLIENT_SECRET.
In Admin → Gmail, choose Connect Gmail and approve.

Check it works

Send yourself an email from a customer's address and watch it arrive in the inbox within 10 minutes. Book a meeting and find it on your calendar.
