Card creation utilizes a hybrid flow that attempts to process requests synchronously but switches to asynchronous processing for longer operations.

1. Request: Submit the card creation request.
2. Immediate Response (< 30s): If processing completes within 30 seconds, the Card UUID is returned directly in the response body. No further action is required.
3. Delayed Response (> 30s): If processing exceeds 30 seconds, the system handles the request asynchronously. You can retrieve the result using one of the following methods:
   3.1. Method A (Recommended): Configure a webhook to receive an event notification immediately upon card creation.
   3.2. Method B (Polling): Manually retrieve the card data. We recommend waiting 3–5 seconds before calling the GET All Cards endpoint to ensure the new card appears in the list.
