The Reddit integration lets Helios agents manage subreddits, post content, moderate communities, track submissions and comments, and work with Reddit's platform directly.
What your agents can do
Helios agents don't work from a preset list of actions. They semantically search the entire Reddit API and call any endpoint directly, with authentication handled server-side. Anything your Reddit account and app scopes allow, an agent can do on your behalf.
- Search subreddits and posts and summarize what's trending
- Submit a post or comment to a subreddit
- Pull a user's or subreddit's recent activity
- Vote, save, and manage flair on content
- Run moderation actions (approve, remove, ban) in subreddits you moderate
- Read and send private messages
Authentication
| Method | Type | Description |
|---|---|---|
| Helios Reddit app (recommended) | OAuth 2.0 | Seamless integration with automatic permissions |
| BYO Reddit app | OAuth 2.0 | Custom Reddit app for enterprise requirements |
Helios Reddit app (recommended)
The Helios Reddit app connects through a standard OAuth redirect flow with automatic permission management. Choose it in Helios, authorize access to your Reddit account, and Helios handles token refresh for you.
BYO Reddit app
Bring your own Reddit app when you need your own branding on the consent screen or your own scope set. Reddit issues tokens to the app that requested them, so you complete the authorization once yourself and give Helios the result. See authentication for the general model.
- Go to Reddit app preferences and create a web app. Set the redirect URI to a URL you control. Copy the client ID and client secret.
- Authorize the app once with
duration=permanentand the scopes your agents need. Reddit returns an access token and a refresh token. Reddit's OAuth guide describes the steps. - In Helios, choose BYO Reddit app and fill in the fields below.
| Field | What to enter |
|---|---|
| Client ID | From your Reddit app |
| Client secret | From your Reddit app |
| Access token | From the authorization in step 2 |
| Refresh token | From the authorization in step 2 |
| App name | An identifier such as MyHeliosApp:v1.0.0. Reddit requires it in the User-Agent header. |
| Username | The account that owns the app, in the form /u/username |
Helios stores the credentials envelope-encrypted and refreshes the access token when it expires. Agents can only call endpoints covered by the scopes you granted.
Triggers
Reddit does not emit event triggers into Helios. Only GitHub, Slack, and Plain do. Use Reddit from chat, or from a workflow started by a schedule, webhook, or manual trigger.
