This event source emits events each time a new message is delivered to a Discord channel. By default, it emits an event for every message.
To use this source, you'll need to create a Discord bot and add that bot to your server(s). If you haven't created a Discord bot, see these instructions or watch this video.
When you create this source, you'll be prompted to connect your Discord Bot token (press Connect Account and then New to add your token). The source will use that token to list the guilds / channels that bot has access to, asking you to select one:
We use Discord's API to poll for new messages in this channel once a minute, by default, but you can increase this to run up to once every 15 seconds, if you'd like.
The first time this source runs, it fetches up to the last 100 messages sent to your channel and stores the ID of the last message delivered to that channel. The next time the source runs, it polls your channel for messages sent after that ID.
By default, this event source is configured to emit an event for every new message in the channel. For example, if 5 messages are sent to the channel in one minute, the source will emit 5 events, one for each message. You can set the source to batch the events the source collects and emit them as a single event by setting the Emit messages as a single event parameter to true.
In this example, the source would emit a single event: an array of 5 messages.
