[TRIGGER] Minecraft integration

Describe the event source. What app is this for, and what event does the trigger correspond to?

A Minecraft integration to trigger an event when a player connect to a server, talk in the chat or execute a specific command. and btw it can be cool if it can also work as a step

That could be useful to server owner that want to automatically send a message to a player when he joins the server for the first time, or to edit a Google Sheet that contains all information on every player.

Please provide a link to the relevant API docs for the specific service / operation this trigger is tied to.

There's no API as it's not really a service, but the integration can be done by making a plugin or mod that need to be added to the server, there is a documentation for developing a plugin using Spigot and Java here (yea if you don't really know the game all these terms can be hard to understand)
