In our ASP.NET billing system that employ SQL 2005 (Express) we need several improvements. We need a payment module implemented for the 3rd party payment gateway that deals with the retail payment terminals. It should employ a slightly different algo: 1. Customer approaches payment terminal and chooses to pay to our company. 2. Customer enters the unique customer identification number. 3. Payment gateway checks the number with our system (i.e. the module that we want should: - accept the number from the gateway and check if it exists - Create a record in a special “Payments?? table with a status “Payment transaction initiated but not finished (not paid)?? 4. If the check is positive, gateway accepts the cash from the customer and processes the payment 5. Gateway sends the payment confirmation to the module and the module: - marks the transaction as paid in the “Payments?? table (payment type = 16 ??" i.e. terminal payment) - changes “Balance?? value in the table “Customers?? - sends an e-mail to specified e-mail addresses (to root, reseller and customer, all gotten from the specified tables) confirming that the payment have been sent ??" our project already have a mail sending module (that is called simply: “…….[login to view URL](String to, String from, String subject, String body); ………..??) Overall from the part of our system the module deals with 2 tables - “Payments?? and “Customers??, layout of each will be provided to a winner. From the part of the payment gateway, we have a set of documents that describe the communication between gateway and the module that are done in a form of http encapsulated xml requests ??" actually 2 requests and 2 replies ( according to the algo ??" steps 3 and 5). I would prefer a developer able to read Russian language to be able to read the gateway specifications, however we are in a process of getting the description in English, however am not sure if we would succeed in this. Not to mention that all copyrights are ours.
