Authentication

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

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