Please follow the documentation in the Make Help Center for connecting personal Google accounts.

1. Enable the API

Direct Link: Google Cloud console


2. Insert all the known Google Redirect URIs for your app

Direct Link: https://console.cloud.google.com/apis/credentials

How to create an OAuth app in GCP: https://www.make.com/en/help/tutorials/calling-google-apis-via-the--http-make-a-oauth-2-0-request--module ← FOLLOW THIS

Here are all the known redirect URIs you need for your Google Cloud Console OAuth app. If you set these up, you can reuse the same GCP app for other Google apps and modules on Make.


Once you’ve set these up, you can use/reuse the same Make connection for all the supported Google apps & modules on Make - you’ll only have to enable the respective APIs for your custom app in Google Cloud.

3. Publish your GCP OAuth2 app

Direct Link: https://console.cloud.google.com/apis/credentials/consent

You might need to set your OAuth application to “Production”, otherwise the credentials expire very frequently.

1. To do this, go to menu item “OAuth consent screen”

or click here https://console.cloud.google.com/apis/credentials/consent

2. Then click the button below if the Publishing status is not “In production”
