Access the Mastercard Gateway
Before you perform test transactions, ensure connectivity to the Mastercard Gateway.
If you have any IP-level restrictions, you may need to whitelist the Mastercard Gateway IPs.
Contact the Mastercard Gateway Support team to obtain the required IP list if whitelisting is needed.
To check the connectivity, access the following URL through a web browser:
Batch: https://na.gateway.mastercard.com/batch/information
If the gateway processes the requests successfully, the "information" file displays status as OPERATING.
