  • a Google account

Follow these steps to create a custom OAuth client for Google services:

  1. Sign in to Google Cloud Platform using your Google credentials.

  2. Open the Dashboard, and click the CREATE PROJECT button.

  3. Choose a name for your project, then click Create.

  4. Click Enable APIs and services.

  5. In the Enable APIs and services field, enter the name of the service you want to use (for example, Gmail API, Google Drive API, or YouTube Data API v3).

  6. The desired service option should display as you type. Click the API/service you want to connect to Make.

  7. Click Enable.

  8. Go to APIs & Services > OAuth consent screen settings, choose the External option, then click Create.



    You will not be charged when selecting this option. For more details, refer to Google's Exceptions to verification requirements.

    For the Test Users section:


    The Optional Info section is displayed only for non-Google Workspace users and does not contain any required fields.


    This step is required, otherwise, you won't be able to establish a connection with Make.

    Click Add users to add the email address associated with the Google account you want to connect to Make.

  11. Open the Credentials settings page.


    If this is not the first API/SERVICE (Gmail or Google Drive) you have enabled, you don't have to create credentials, as you have already created the credentials previously.

  12. Click + Create credentials, and select the OAuth client ID option.

  13. Fill in the required fields as follows, then click Create.

    Application type

    Web application


    Enter the name you want for your application.

    Authorized redirect URIs

    Add one of the following URIs:

    • - for Gmail or Google Drive

    • - for other Google apps

    • - for Google Text-to-Speech

    • - for YouTube

    • - for any app created via  Make Developer Platform.

    • - for Google Cloud Speech

    OAuth redirect URI domain

    Notice that the redirect URI starts with instead of This is currently a known issue in Make.

    Make was formerly called Integromat, which means you can trust this URL as much as any Make URL.

  14. A dialog containing the app's Client ID and Client Secret is displayed.

  15. Go to your Make scenario and choose the Google module you want to use.

  16. Next to Connection, click Add.

  17. Click Show advanced settings.

  18. Enter the Client ID and Client Secret you retrieved in step 14 (above) to the respective fields, then click Continue.

  19. Sign in with your Google account.

  20. The This app isn't verified window appears.


    The app = your OAuth client you have created above.

    Click Advanced, and then on the Go to Make (unsafe) link to allow access using your custom OAuth client.

  21. Click Allow to grant Make permission.

  22. Click Allow to confirm your choices.

You have now established the connection to the desired Google service using a custom OAuth client.

Common Problems

This happens rarely, but when it does, we recommend creating another OAuth client.

If this error message appears, you need to enable the corresponding API in your Google Cloud Platform.


Google has added the required settings for the Consent screen. You'll need to add the email address associated with the Google account you want to connect with Make as a Test user.

  1. Sign in to the Google Cloud Platform using your Google credentials.

  2. Go to APIs & Services > OAuth consent screen.

  3. In the Test Users section, click Add users to add a test user. Enter the email address associated with the Google account you want to connect with Make, and click Save.

  4. Now, go to Make, and connect to the desired Google service.

Your connection has expired and is no longer valid. You need to reauthorize the connection.

This error affects non-Google Workspace accounts. For more details please refer to the Google OAuth documentation.


Reauthorize your Google connection by following these steps:

  1. Log in to Make.

  2. Go to Connections.

  3. Find your Google connection and click Reauthorize button.


    To prevent the expiration of your Google connection, we suggest you to reauthorize the connection every week.
