Payment Express provides merchants with several interfaces for developing custom built payment solutions.
APIs (Application Programming Interfaces) allow merchants to send transactions from a variety of platforms including but not limited to websites, billing software, vending machines, parking machines and batch processing.
Please note that some banks mandate that merchants use a Payment Express DPS Hosted solution when developing websites.
There are several APIs that developers can use to communicate with Payment Express. These include:
| PXPost | XML posts directly from client application to Payment Express |
| COM object solution | |
| Simple SOAP connection |
Developers may also use these Merchant hosted APIs in conjunction with the DPS Hosted APIs in order to utilize Visa and MasterCard’s 3D secure security mechanism.
