* **Accounting Sync**: Keep your books in sync automatically
* **CRM Integration**: Update customer records with usage and billing data
* **Notifications**: Alert your team about important events
* **Custom Workflows**: Build custom integrations for your needs

## How Extensions Work

Extensions are event-driven:

1. **Event Occurs**: Something happens in Valmi Value (invoice created, payment received, etc.)
2. **Extension Triggered**: The extension receives the event
3. **Action Taken**: Extension performs an action (charge customer, update CRM, send notification)
4. **Result Recorded**: Extension reports success or failure

## Extension Architecture

Extensions support bidirectional data flow:

### Outbound Flow (Valmi Value → External System)

```
Valmi Value → Event → valext Extension → External System
                ↓
         Response/Status
```

### Inbound Flow (External System → Valmi Value)

Extensions can also work as ingestion into Valmi Value through webhooks:

```
External System → Webhook → valext Extension → Valmi Value
                                    ↓
                            Response/Status
```

Extensions run as separate services that:

* Subscribe to Valmi Value events (outbound)
* Receive webhooks from external systems (inbound)
* Transform data to match external system formats
* Call external system APIs
* Handle errors and retries
* Report status back to Valmi Value
