Vertex Gemini Integration - Not working

Hi,

I am trying to integrate Google Vertex AI (Gemini) into make.com and have been following each step of the guide: https://www.make.com/en/help/apps/ai/google-vertex-ai (even billing is enabled.)

However, I consistently get “[403] Request had insufficient authentication scopes.” - However, there is no way to change/enter the authentication scopes (OAuth?).
What do I need to do to get this working?
Thanks,
Patrik

Solved. The second (collapsed part of the guide) had the clue. I followed the steps there and it is now working.

Welcome to the Make community!

Well done on solving the scopes issue on your own! Here is additional information for future reference:

See the “Add the relevant scopes” below for more information

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

1a. Enable the relevant API

Find the relevant API here: Google Cloud console
Go to API page, end click “Enable”

1b. Add the relevant scopes (or all of them)

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

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

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

Here are some 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 APIs for your custom app.

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”

4. Set up connection (HTTP OAuth, or respective Google App)

A. HTTP OAuth2

You need a “Authorize parameters” key of redirect_uri with the above Make OAuth2 callback URL.

You can find the Client ID and Client Secret in the OAuth2 app you created in GCP, on the right-hand side of where you inserted the 8 callback URLs in step 2:

B. Google App

Insert the GCP app client ID and secret here BEFORE clicking “Sign in”
