This document provides information for integrating a payment processing service. It includes the live and test URLs, required fields for requests and responses, sample JSON templates, and instructions for generating checksum values for validation. Mandatory fields include bank account number, IFSC code, mobile number, sender name, amount, currency, merchant ID, order ID, and checksum. Responses return fields like transaction IDs, status, response code, and message.
