Advanced Integration Method (AIM)

The Advanced Integration Method is the recommended method of submitting transactions to the payment gateway. This method allows a merchant's server to securely connect directly to the payment gateway to submit transaction data. The merchant retains full control of the payment data collection and the user experience. This method requires merchants to be able to initiate and manage secure Internet connections.

Simple Integration Method (SIM)

The Simple Integration Method is a relatively simple and secure method to submit transactions to the Payment Gateway. Merchants using this method have the option to let the gateway handle all the steps in transaction processing-payment data collection, data submission, and response to customer. Any request to the gateway is required to contain information that indicates to the gateway that the transaction is authentic and has been submitted for processing with the merchant's knowledge. This information is contained in a fingerprint that has to be generated by the merchant and included with every request submitted to the gateway. The fingerprint is a hash generated using the HMAC-MD5 hashing algorithm on a set of pre-defined transaction-specific fields. If the fingerprint cannot be validated by the gateway, the request will be rejected.
