## Description

PayNexus Payment Gateway lets you accept M-Pesa mobile money payments on your WordPress
website. Money flows directly from the customer to your own M-Pesa payment account—
PayNexus never holds or delays your funds.

**Features:**

 * M-Pesa STK Push — Customers receive a payment prompt on their phone
 * WooCommerce integration — Full checkout gateway for WooCommerce stores
 * Shortcode support — Embed payment forms on any page with `[paynexus_payment_form]`
 * Real-time polling — Automatic status updates without page refresh
 * Webhook support — Receive instant payment notifications via REST API
 * Admin dashboard — View and filter all payments from WordPress admin
 * Secure — HMAC-SHA256 webhook signature verification with replay protection
 * Local records — Every payment is stored locally for your records

**How It Works:**

 1. Customer enters their phone number and amount
 2. PayNexus sends an M-Pesa STK Push to the customer’s phone

 5. WooCommerce orders are marked as paid automatically
