Discord Bot Overview#

The Pipedream Discord app enables you to build event-driven workflows that interact with the Discord API. When you authorize the Pipedream app's access to your guilds, you can use Pipedream workflows to perform common Discord actions, or write your own code against the Discord API.

Trigger Configuration#

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI and CLI.

Label	Prop	Type	Description
Discord Bot	`discord`	`app`	This component uses the Discord Bot app.
Guild	`guildId`	`string`	Select a value from the drop down menu.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Channels	`channels`	`string[]`	Select a value from the drop down menu.
Emit messages as a single event	`emitEventsInBatch`	`boolean`	If `true`, all messages are emitted as an array, within a single Pipedream event. Defaults to `false`, emitting each Discord message as its own event in Pipedream
	`timer`	`$.interface.timer`

Trigger Authentication#

Discord Bot uses API keys for authentication. When you connect your Discord Bot account, Pipedream securely stores the keys so you can easily authenticate to Discord Bot APIs in both code and no-code steps.

This app allows you to use the Discord API using your own Discord bot. If you don't want to use a custom bot, and you just need to use the Discord API, exit this screen and use the Discord app, instead.

If you want to use your own Discord bot, but haven't created one yet, see these instructions or watch this video. You'll need to add this bot to your server(s) to make successful API requests.

Once you've created your bot, you'll find the Bot token within the Bot section of your app. Enter that token below.
