How to query Azure OpenAI model in Power Automate

Hi,

When I used the public OpenAI model, I do a POST to its endpoint URL https://api.openai.com/v1/chat/completions, for example.

Then in the content type, I used key Content-Type=application/json and Authorization=Bearer "My OpenAI API Key".

Now I have created the Azure OpenAI resource and deployed my own GPT 3 model.

I see my endpoint URL, what about the rest?

Do I use the same format as

Content-Type=application/json

Authorization=Bearer "My Azure OpenAI API Key

I couldn't get it working and when using POSTMAN, it just says resource not found.

Thanks,
