Payment gateway is an e-commerce application service that authorizes payments for electronic businesses. It is an online equivalent of possible physical payment methods. Payment gateways protect credit card and bank accounts details by encrypting sensitive information, such as credit card numbers, to ensure the securely transfer of that information between the customer and the payment processor.
Payment gateway integration is the process of making your website or online store possible to let customers use the purchased payment gateway service for purchasing products or services offered. During this process we study the API's provided by Payment Gateway service provider (e.g. PayPal) for features required to be implemented and work on coding to interact with API. Here, the word API represents the Application Programming Interface, being a point of interaction on Payment Gateway servers to let your website's code interact with.
We have worked on different payment gateways to implement many kinds of payment processing scenarios, such as:
- Instant payments
- Single time payments
- Recurring payments
- Mass payments
- Chained payments
