Batch Upload Purchase Vault

The documentation for IssuerID reads as in red below.

Under what conditions would the IssuerID returned in Batch Upload Vault Purchase not match the IssuerID transmitted?

Thanks

 

The IssuerID must be saved to your systems when returned from Moneris Gateway in the response data, regardless if the value was received or not. As a best practice, if the IssuerID is not returned and you received N/A instead, store it and send it in the subsequent transaction.
