Our products and services can be deployed on most web servers in any environment, and we are affiliated with several storefront applications. Just let us know which solution you have chosen and we will do our best to make your foray into eCommerce quick and easy.

Integration and API

Merchant solutions are integrated by creating an application or modifying an existing application to incorporate our Application Programming Interfaces (APIs). We provide simple and secure XML or HTML APIs that work in any internet environment. The required data structures are fully described in the XML or HTML posting API technical documentation. You are more than welcome to review and even test with our test account in advance of setting up a PSiGate account.

Click here to download our Real-time HTML API. The Real-time HTML API allows customers to process real-time credit or debit card transactions via a browser to server connection. This API is suggested for integrations that are simple, require PSiGate to collect the card information or require communication to occur over standard ports. Interac Online transactions must be processed through the HTML API.

Click here to download our Real-time XML API. The Real-time XML API allows customers to process real-time credit card transactions via a server to server connection. This API is suggested for integrations that are highly customized, complex, do not require PSiGate to collect credit card information and can afford to occur over dedicated, non-standard ports.

Click here to download our Account Manager API (Recurring Billing service and more). The Account Manager XML API allows merchants to securely store their customer's data within accounts that may be billed later via recurring, installment or immediate charges. Additionally, the API allow merchants to update and query account charges, charge templates, invoices and email reports. This API is suggested for integrations that involve recurring charges (whether or not the amounts vary), trial-based charges, installment charges, and can afford to occur over dedicated, non-standard ports.

Click here to download our PSi3D HTML API (Verified by Visa and MasterCard SecureCode service). The PSi3D HTML API allows merchants to reduce fraud by forcing their customers to associate a PIN with their card and input that PIN for validation prior to the order being accepted.
