Overview
The Hot Sale process documentation consists of two parts: interaction with the bank and interaction with the user (seller).
The Hot Sale flow is as follows. The seller, while located at the buyer’s point of sale, creates a shipping document specifying the cost of goods and the bank through which the payment will be processed (make_shipping). After that, the T&T system generates an invoice and sends it to the bank (pay_invoice). The buyer then completes the payment in the banking application.
Based on the payment processing result, the bank sends the payment status information to the T&T system (/sale-api/pay_result/). The T&T system, in turn, sends the payment result to the seller’s ERP system (pay_status). If the sale is completed successfully, the goods are automatically transferred to the buyer’s balance without requiring any additional confirmation from the process participants.
The documentation also describes the Cold Sale mode. In this flow, the buyer independently creates a shipping document (make_shipping), which is then sent to the bank (ship_invoice). After that, the buyer can accept or reject the document either in the banking application (/sale-api/ship_result) or through the T&T application. Unlike the Hot Sale mode, this flow does not involve actual payment processing through the bank. Confirmation of the document serves as the basis for completing the operation and transferring the goods to the buyer’s balance.
