Payment Gateway Integration
Payment Gateway Integration refers to connecting online payment systems to websites or apps so customers can pay electronically. It's like adding a digital cash register to a website. When companies need someone who can work with payment systems like PayPal, Stripe, or Square, they look for this skill. Think of it as building a bridge between a business's website and the banking system that processes credit cards and other online payments. This is essential for any business that wants to sell products or accept payments online.
