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.

Action Authentication

Twitch uses OAuth authentication. When you connect your Twitch account, Pipedream will open a popup window where you can sign into Twitch and grant Pipedream permission to connect to your account. Pipedream securely stores and automatically refreshes the OAuth tokens so you can easily authenticate any Twitch API.

Pipedream requests the following authorization scopes when you connect your account:
