Magento 2, create Json file containing information about users and products asigned to that user

Job ID: 34098564

Budget: €30 – €250 EUR

We are trying to get access to that information by reading a JSON file that contains the Data Structure, but we are not able to create that Json File, we don't know how to get the API working.

Ideally we want someone to come, jump in a call, guide us through the steps to create that JSON file, and as soon as we successfully access the JSON link and print some text, the job is finished.

This is more about helping with a bottleneck than about getting something functional done.
