1. Submission with Instant Response

  • Description:
    This method processes the transaction synchronously. The API immediately returns a response containing the result of the transaction.

  • Response Handling:
    The response includes the final status, risk level and final action to be taken directly in the API response.

  • Use Case:
    Best for applications that require real-time confirmation of the transaction outcome.


2. Submission with Webhook Response

  • Description:
    This method processes the transaction asynchronously. Once the transaction is submitted, Sigma will handle the processing in the background.

  • Response Handling:
    The final transaction result (including status and details) will be sent to a webhook URL that you specify.

  • Use Case:
    Ideal for scenarios where you don’t need an immediate result and prefer to receive transaction outcomes via a background callback.
