Obtain ARN of the transaction from the acquirer

Description:
Add the ability to retrieve the Acquirer Reference Number (ARN) for each transaction directly from the acquirer.

Problem:
The ARN is not currently provided, which makes it difficult to:

• Track payments with issuing banks

• Speed up reconciliation

• Handle disputes efficiently

Proposed Solution:
Request and store the ARN from the acquirer and expose it through our APIs or dashboard.

Expected Benefits:

• Improved transaction traceability

• Faster support and reconciliation

• Better dispute management
