MerchantAPI is a WSDL compliant web service that uses SOAP (Simple Object Access Protocol) protocol for transferring information.
Information security is ensured by the use of HTTPS (Hypertext Transfer Protocol over Secure Sockets Layer). All information requests are authorized with a unique combination of Username (API username) and Password (API password).
With implementation of MerchantAPI the interaction with customers while selecting merchandise, forming an order as well as the transaction registration are done on the merchant website.
