Hello, I’m currently developing a web application for some runners at my school and I would like to create an integration for Garmin Connect. I see that some other websites have an OAuth looking integration where it redirects you to Garmin Connect to login and then syncs with their website. Where can I find materials on how to go about an integration like this? Is the API free to access? I look forward to hearing back from whomever can help me on this journey!
