How to use Gemini 3 Flash in make.com

How to automatically generate blog articles using Gemini 3 Flash and Make.com

What is the problem & what have you tried?

In my workflow, I have an “HTTP Make a Request” module that contains the URL https://generativelanguage.googleapis.com/v1beta/models/gemini-2.5-flash:generateContent?key=xxxxx(my API key)xxxx to have the Gemini API automatically generate an article for my blog. I want to use the Gemini 3 Flash version because it’s better and free, but it seems that make.com doesn’t support it based on the errors I’m getting. I need to know the exact name the URL should have, how it should be worded, to make the Gemini 3 Flash model work. If the problem is that make.com doesn’t support this latest model, I’d like to know who I need to contact or what I need to do to get make.com updated to support the Gemini 3 Flash content generation model. Thank you very much.

Hey there,

If you are using the generic http module, it doesn’t matter what make supports or doesn’t.

You should be able to find the correct API endpoint in Google’s documentation. Best guess is - change 2.5 to 3.0

Hi Manuel - Welcome to the Community!

You’ll find it much easier to use the Google Gemini AI app in Make.

The Simple text prompt module is the simplest - you don’t need a Gemini key or account, instead you’re billed for usage through the Make credits system.

If you want more control, or if you want to use your own Gemini API Key, you’ll use the Generate a response module:

Gemini 3 Flash is available in both modules.

The correct URL is :
https://generativelanguage.googleapis.com/v1beta/models/gemini-3-flash-preview:generateContent
Also, there is no need to include an API key in the URL, as it may be stolen or misused due to accidental exposure or sharing. Instead, configure your credentials/keychain to use an API key in the headers and use x-goog-api-keyin the API Key parameter name.
