I have the credentials to access an API, I am able to access and make some calls that returns data with my PHP site. I have the URL and am sending the correct GET request and headers but I need an example of how to create a file download app.

The way I see it I will create a link that when I click on it in Firefox it will pop-up the box that asks me where I want to save the file. Where can I find an example that shows how to download content (zip archive in this case) from a 3rd party server using their API?

Thank you
