# PaaS Integration

Build your integration with FinHub PaaS connectors.

## Integration Steps

1. **Get Credentials**: Obtain sandbox API credentials
2. **Configure**: Set up connector-specific settings
3. **Develop**: Build integration using APIs
4. **Test**: Validate in sandbox environment

## Authentication

All connectors use OAuth 2.0:

```bash theme={null}
POST /paas/oauth/token
```

## Common Integration Pattern

```json theme={null}
{
  "connector": "connector_name",
  "operation": "operation_type",
  "data": { ... }
}
```

## Best Practices

* Use idempotency keys
* Implement webhook handlers
* Handle errors gracefully
* Log all transactions
