Getting Started

This integration creates a workflow with a Discord Bot trigger and Data Stores action. When you configure and deploy the workflow, it will run on Pipedream's servers 24x7 for free.

  1. Select this integration
  2. Configure the New Message in Channel trigger
    1. Connect your Discord Bot account
    2. Select a Guild
    3. Select one or more Channels
    4. Optional- Configure Emit messages as a single event
    5. Configure timer
  3. Configure the Add or update multiple records action
    1. Connect your Data Stores account
    2. Configure Data Store
    3. Configure Data
  4. Deploy the workflow
  5. Send a test event to validate your setup
  6. Turn on the trigger

Details

This integration uses pre-built, open source components from Pipedream's GitHub repo. These components are developed by Pipedream and the community, and verified and maintained by Pipedream.

To contribute an update to an existing component or create a new component, create a PR on GitHub. If you're new to Pipedream component development, you can start with quickstarts for trigger span and action development, and then review the component API reference.

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.

If you haven't created a Discord bot, see these instructions or watch this video. You'll need to add this bot to your server(s).

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

About Discord Bot

Use this app to interact with the Discord API using a bot in your account
