Accessing Google Gemini 3 Pro with n8n

Hey WebNutch community, I've created a workflow that allows customers to book appointments based on my Google Calendar, and it's been a game-changer. However, I'm still using Gemini 2.5 Pro for appointment selection, and I think Gemini 3 Pro could do the job even better and more efficiently. I'm wondering if anyone in the community has figured out how to connect to Gemini 3 Pro in n8n using the Google Gemini chat model. It seems like an update that would be really beneficial, and I'm hoping someone has found a solution. Has anyone had any luck with this, or are there any alternative approaches that could achieve similar results? I'd love to hear about your experiences and learn from them. Maybe we can even find a way to make this work together and share it on the WebNutch marketplace for everyone to benefit.

I've been experimenting with the Google Gemini chat model in n8n, but I haven't figured out how to connect to Gemini 3 Pro yet. Have you tried using the new API endpoints?

Thanks for the tip on using the 'gemini-3-pro' endpoint! 🙏 I'll give it a try and see if I can get it working. Has anyone else had success with this approach?

I'd love to see an example workflow for booking appointments with Google Calendar and Gemini 2.5 Pro. That sounds like a really useful automation!

Regarding your question on connecting to Gemini 3 Pro, I think I can help. I've been working on a similar project and I found that you need to use the 'Google Gemini Chat Model' node in n8n and specify the 'gemini-3-pro' endpoint. Does that make sense?

@n8nNewbie, I can share my workflow with you! It's still a work in progress, but I can give you a general idea of how I've set it up. I use a 'Google Calendar' node to fetch available time slots, and then I use a 'Gemini 2.5 Pro' node to generate a list of available appointments. Then, I use a 'HTTP Request' node to send the booking request to my server.

Great tip on using Google Calendar with n8n! 📅 I've been trying to implement something similar, but I'm still on Gemini 2.0 Pro. Can you share more about how you've set up your appointment selection workflow?
