Prerequisites

• Node.js and npm installed.
• An active Safaricom account with access to the Daraja API.
• Environment variables set up for Safaricom API credentials.

1. Clone the Repository

   git clone <repository_url>
   cd <repository_directory>

   CONSUMER_SECRET=your_consumer_secret
   SHORT_CODE=your_shortcode
   PASSKEY=your_passkey

   Replace the placeholder values with your actual Safaricom API credentials.

Code Overview

The script contains two main functions:

1. getAccessToken
