Asynchronous (Recommended)

Synchronous

The HTTP connection remains open to receive the final status from the operator.
Response time varies; the system waits up to 180 seconds (configurable upon request).
The response includes either a final status (COMPLETED, DECLINED, REVERSED, CANCELLED) or an intermediate SUBMITTED status, depending on the operator's processing time.
If SUBMITTED, the transaction is still being processed by the operator.
Applications can close the connection early and query the final status later.

Upon transaction confirmation, the transfer order is sent to the operator for immediate processing, and the transaction enters a CONFIRMED status.

Obtaining Final Transaction Status

Regardless of the processing mode, your application must capture the final transaction status. This can be achieved in the following ways:

API Query (Pull)

Callback URL (Push)

Receive status updates by configuring a callback URL in the transaction creation request.
