Widget to show app activity

Hey!

Would really appreciate some help on a problem that I’m facing. A client wants a website to showcase an app that they are building. In the website, they want a pop-up/section that lists the recent activity in the form of transactions on the app.

I’m guessing this would require an API call to be made to the app backend and the JSON data returned to be bound with the elements.

Another option would be to use the cms API to update a collection from the app-end?

I was wondering if I’m missing out on any other solution or a 3rd party app that will help me out with this problem.
