What is an API?
An API, or Application Programming Interface, refers to a set of rules and protocols which allow different software systems to communicate with each other. APIs enable systems to exchange data and perform functions without requiring direct access to internal code.
How are APIs used in payments?
Payment APIs connect websites, mobile apps, and software platforms to payment services. For example, an ecommerce website sends payment requests to a payment gateway using an API. The gateway processes the request and returns a transaction result.
Why are APIs important in payment technology?
APIs allow payment services to integrate quickly with merchant systems. Businesses connect checkout pages, subscription systems, or billing platforms directly with payment providers. This reduces manual processes and improves payment automation.
What is an example of a payment API?
A payment gateway API represents a common example. When a customer submits payment details on an online checkout, the website sends those details to the payment gateway through an API. The gateway processes the transaction and returns approval or decline results.
Are payment APIs secure?
Payment APIs operate with authentication systems, encrypted communication, and strict access controls. Many providers require API keys or secure tokens to verify authorised requests and prevent unauthorised access.
