M-Pesa STK Push and Callback Integration

This project is a Go-based implementation for integrating M-Pesa's STK Push and Callback functionalities. It includes components for initiating STK Push requests, handling M-Pesa callbacks, and saving callback data to a PostgreSQL database.

Features

• STK Push: Initiate a payment request using M-Pesa's STK Push API.
• Callback Handling: Handle callback responses from M-Pesa and save them to the database.
• Asynchronous Processing: Save callback data in the background without blocking other processes.

Prerequisites

• Go: Ensure you have Go installed. You can download it from golang.org.
• PostgreSQL: You need a PostgreSQL database to store callback responses.
• Ngrok: For local development and testing with M-Pesa, you may use Ngrok to tunnel requests.
