Access the MCB Payment Gateway
Before you perform test transactions, it's important to check the connectivity to the MCB Payment Gateway.
To do this, try and access the following URL through a web browser:
REST:https://mcb.gateway.mastercard.com/api/rest/version/1/information
NVP:https://mcb.gateway.mastercard.com/api/nvp/version/1/information
If the gateway is able to process requests, i.e., if successful, the "information" file displays {"status":"OPERATING"} in the JSON format for the REST protocol. NVP displays status=OPERATING.
