# Message Filters & Routing

Filters determine which Slack messages across your Source Channels get routed into your Hub Channel.

### 🎯 Filter Types Supported

1. **Text Match** (`type: "text"`): Matches specific keywords in message body (e.g. `FATAL`, `Outage`, `DB Connection Error`).
2. **User Mention** (`type: "user"`): Routes any message mentioning a specific user (e.g. `@john.doe`).
3. **Usergroup Mention** (`type: "usergroup"`): Routes messages mentioning a Slack usergroup (e.g. `@oncall-backend`).
4. **Tag Match** (`type: "tag"`): Routes messages with matching tags or hashtags (e.g. `#sev1`, `[URGENT]`).
