Well… let’s be the first one to answer this post:
for the first one: I was using an incorrect value for broadcaster_user_id, I was using ClientID, but is different (I didn’t know).
In the tutorial, it says that the header need parameters:
Client-ID: CLIENT_ID
Authorization: Bearer ACCESS_TOKEN
Content-Type: application/json
but the third line was causing me exceptions. Removing it causes the http request to work… So I don’t know if I misundertstood something, or that part on the tutorial is wrong…
For the second one: I still don’t understand how this lib works, it doesn’t seem to be an standalone applicacion but it seems to work more like a webhook… so i’ll keep doing tests.
