The viaConex solution is a hosted SSL gateway to Elavon for transaction processing. The gateway is designed to process authorizations and perform settlements for both Terminal-Based and Host-Based points-of-sale.
Access to the viaConex server is accomplished through sending a script in the form of an HTTPS Post written in the non-extended ASCII character set. The basic format for the Posts is defined in the Script Overview section. Post examples are outlined in the viaConex tester application, which is provided with this documentation.
The Development Host for development and certification is certgate.viaconex.com.
The Production Host for the viaConex server is prodgate.viaconex.com.
