## Server Logs

When managing accounts, you'll see these log messages:

```log
INFO Account disabled account_id=business
INFO Config saved after disabling account account_id=business

INFO Account enabled and connected account_id=business
INFO Config saved after enabling account account_id=business

INFO Account configuration updated account_id=business
INFO Account reconnected with new settings account_id=business

INFO Skipping disabled account account_id=business
```

## Best Practices

1. **Disable vs Remove**:
   - Use **disable** for temporary disconnection (maintenance, testing)
   - Use **remove** for permanent deletion

2. **Update Process**:
   - Always provide complete configuration when updating
   - Account will be reconnected automatically if enabled

3. **Session Management**:
   - WhatsMe ow sessions are stored in `session_path`
   - Removing an account doesn't delete session files
   - Clean up manually if needed

4. **Server Restart**:
   - Only enabled accounts (`disabled: false`) connect on startup
   - Disabled accounts remain in config but stay disconnected

5. **Configuration Backup**:
   - Config is automatically saved after each change
   - Keep backups before making bulk changes
   - Test changes with one account first

## Error Handling

All endpoints return proper HTTP status codes and JSON error messages:

```json
{
  "error": "Account not found"
}
```

Or plain text for simple errors:
```
Account ID required in path
```

Common error scenarios:
- Account already exists (when adding)
- Account not found (when updating/removing)
- Connection failed (when enabling)
- Configuration save failed (any operation)
