What's interesting about this integration is that my app uses Firebase for the backend so I had to navigate and merge the available features in Firebase and Zapier to create what I now believe is an efficient and secure integration! 🚀
I think it turned out well and, in the end, I was able to create it just using the visual builder (there was a bug that prevented pushing code with the CLI at the time).
If you're using Firebase for your app, I might be able to offer some help as it was at times not at all obvious to me how to accomplish certain things. Just let me know!
