Hey there coders!
I got in a project where my client needed basically all Data Collections open through an external API so that other systems could reach data from endpoints and get all data as JSON. I thought about this and how I could create that for 32 Data Collections with one function only. It is just 40 lines of code and it works like a charm.
In this tutorial I will show you how I did it and the source code is also here.
