Twitch TV - Clarifications about the API

I can really use some help with the Twitch Api. I’m working on building the http request.

Using these instructions and this base URL’ should I use this documentation (V.3, there is already V. 5) ? At the moment all I have is the URL for the request: “”.
I was recommended by Any suggestions (such as parameters) for completing the request?

At the Chat I was recommended to simply explore the JSON for a certain URL such as , but this will give me info relating to one specific channel. I wouldn’t be able to view all current streams.

To complete this project I used 2 requests to URLs:
'' + userName
'' + userName

userName it’s an element of users array. It’s necessary to do requests for each user. See or Array.prototype.forEach()

This is the lesson I made for my students
