Log in or register, to view the original We have a program that allows you to print on the printer the cash checks that the server sends (we use a web socket) You need to connect the program with the PAX A930SL terminal from a private bank.1 .A request from the server. The 2ndWith the driver, the exchange with the terminal is carried out (scripture of funds from the card and receipt of checks) 3 .sending data to the server Request from the web-sock server to the program (data from the terminal): {"success":true,"action":"terminal_request","data":{"checkout_id":376318,"total":"70.00"}} Here is the naked action = terminal_request checkout_id - the check number in our system Total - the amount to be paid by the terminal In response, our web-socket server is waiting for this {"acquirer_and_seller":"sdcsdcsdc","auth_code":"ssdcsdc","bank_name":"sfvfvdfv","card_mask":"2342424","checkout_id":376318,"event":"terminal_response","owner_name":"sdcsdcsd","payment_system":"sdcsdcsdc","receipt_no":"sdcsdcd","rrn":"dfvdfvdfvv","signature_required":"0","terminal":"sdcsdc","token":"9e4df314f48e5a7bd805070707d747fbc256febea" Here is the main event = terminal_response The answer to such a request from the web-sock server will be standard: {"success":true,"action":"terminal_response","data":[]} –– Unfortunately, the freelancer who was doing the program is now busy.But he suggested how this can be done: The private bank has a unified program for the exchange of data.The program is a WebSocket service that can be used to exchange data.In principle, you can realize the exchange of data with these terminals, through the PRIVATBANK program.Documentation and drivers (which found the author of the code), as well as the program code will be downloaded by the executive.
