Configuration

Depthdepthinteger

If set to 1, it will include, in the emitted event, only new comments that are direct children to the subreddit pointed by "subredditPost". Furthermore, "depth" determines the maximum depth of children, within the related subreddit comment tree, of new comments to be included in said emitted event.

If set to true, subreddit details will be expanded/included.

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:
