Integrating with your custom backend
The use of GestPay, and therefore also of the WSs2s module, is reserved for companies which entered in the relevant agreements with EasyNolo and Banca Sella regarding the management of online payment transactions and therefore identified as “Participating Merchants”.
A GestPay Participating Merchant is recognizable by an identification code called
shopLogin and is entitled to use the Back Office environment through one or more operators registered on the Sella.it website (at least one operator, with Administrator status is a requirement for activation of the service). But you should already know this.
With S2S (Server To Server) it is possible to build your own administration dashboards and handle your transactions without passing in Gestpay’s backoffice.
As GestPay allows each merchant to decide what information to send to the system (apart from a minimum required series of information), merchants must configure the system appropriately, using the “Fields & Parameters” section in the Back Office (BackOffice -> PaymentPage -> Fields & Parameters).
GestPay, furthermore, only accepts calls from an IP address associated with the shopLogin of the merchant making the call. It is therefore necessary, once again working within the Back Office environment (BackOffice -> Configuration -> Environments -> IPAddress), to configure the IP address of the server that is to make the calls to WSs2s.
