Webhook twitch start

Thank you very much, everything works. I had a few more questions:

  1. So for every event, I have to send new requests? For follower
    'hub.topic' = 'https://api.twitch.tv/helix/users/follows?first=1&to_id=******** http://mysite.com/twitch.webhookfollow.php
    To notify the streamer?
    https://api.twitch.tv/helix/streams?user_id=******** http://mysite.com/twitch.webhookstream.php
    Or perhaps somehow specify the query to receive all events?

  2. The connection will operate 10 days, after which it will stop working right? So you have to put the update on cron, or is the connection not lost?

  3. https://api.twitch.tv/helix/users/follows?first=1&to_id=******** we receive information about all new followers, and is it possible to also receive notifications about all unfollowers? Thanks for your help.
