The organization_id can be found by going to your org dashboard in the TwitchDev Console, the ID is in the URL eg https://dev.twitch.tv/org/ORGANIZATION_ID/console.
The category_id is the id of your game, you can find this by using the Get Games endpoint, or you can go through the Org dashboard, select the game and again the category_id will be in the URL, eg https://dev.twitch.tv/org/ORGANIZATION_ID/console/games/CATEGORY_ID/boxart
As for campaign_id, again, it’s in your Org dashboard on the Drops page there’s a table of campaigns and one of the columns is the Campaign ID.

That’s not documented anywhere. Twitch use AWS currently so it could potentially be any IP from the pool that AWS use, it’s not static and could change at any time.
