### Idempotency

To ensure orders are not duplicated due to network retries or client failures, you can use the `client_request_id` parameter:

- **Purpose**: Prevents duplicate order creation when the same request is retried
- **Cache Duration**: 10 minutes (server-side)
- **Format**: Any unique string per request (e.g., UUID, or a client-generated identifier)
- **Behavior**: If the same `client_request_id` is received within 10 minutes, the server returns the cached response from the original request without creating a new order

#### Idempotency Example

```
First request:  client_request_id="abc123-uuid-request" → Creates order with ID 12345
Retry (same ID within 10 min): client_request_id="abc123-uuid-request" → Returns existing order ID 12345 (no duplicate)
New request:    client_request_id="xyz789-uuid-request" → Creates new order with different ID
```

#### When Omitting client_request_id

If you do not provide `client_request_id` (or pass an empty value), the request will still succeed and create an order normally. However, **idempotency protection will be skipped**, meaning:

- Each request (even identical ones) will create a separate order
- Network retries or accidental duplicate requests may result in duplicate orders
- No server-side caching of the request will be performed

It is strongly recommended to always provide a unique `client_request_id` for critical order submissions to prevent unintended duplicates.
