Solved: How is the systemTraceAuditNumber obtained

haoran

hello，I'm using the https://sandbox.api.visa.com/visapayouts/v2/payouts ，So how is the systemTraceAuditNumber parameter obtained，Is it fixed or arbitrary？

Hi @haoran,

The System Trace Audit Number is a number assigned by the merchant that uniquely identifies a cardholder transaction and all the message types that it comprises. The same trace number is used in an estimated authorization request and response, incremental authorization request and response, and in a subsequent reversal request and response.

Thanks,

@I_Doroteo3 Thanks，Is the number assigned by the merchant, what does the merchant refer to, and how can the developer get the number？

Hi @haoran,

This number is generated by the cardholder bank to identify a cardholder's transaction with a merchant; if you are a merchant you would have to reach out to your acquiring bank to get the STAN.

For this reason, Visa Direct programs/products require the originating entity to be a licensed Visa acquirer or be sponsored by a license Visa acquirer.

Thanks,

Illana

@I_Doroteo3Thank you very much. I understand.

" https://sandbox.api.visa.com/visapayouts/v2/payouts " transactionAmount parameters of this interface is transfer amount, I in the sandbox environment, can't modify the value, Is it because it is associated with the parameter "systemTraceAuditNumber" and "transactionAmount" is also set by the receiving bank?
