What Does API Stand For?
An API meaning an Application Programming Interface. How does API work? This technology makes sure one application knows how to interact with others, including what kind of request it can send, what response it will get, how to deliver them between entities, and how to do it in a secure way. Particularly, API provides safe communication between servers and clients through a gateway.
What is a Payment API?
A Payment API enables transactions to be processed seamlessly through websites, apps, or digital platforms, facilitating interactions among businesses, banks, and merchants. It operates behind the scenes, unlike manual systems or payment gateways that rely on redirection. It enables enterprises to:
- Initiate traditional payments and APMs
- Tokenize information
- Handle payment authorization and capture
- Process refunds
- Manage recurring charges
- Verify customer identity
- Operate with callbacks
- Get balances etc.
Types of APIs in the Payment Sector
The payment industry relies on several Application Programming Interfaces to move data securely between systems like banks, apps, and online stores. Each type serves a unique role in how payment processes are initiated, handled, and confirmed.
REST Application Programming Interfaces
REST stands for Representational State Transfer. It is a widely used method for data exchange between client and server in finance and other industries.
SOAP Application Programming Interfaces
SOAP is a Simple Object Access Protocol known for strict XML formatting and high security. It is used in large financial institutions or enterprise systems where secure data management is a top priority.
GraphQL Application Programming Interfaces
GraphQL stands for Graph Query Language. It is designed to let clients request exactly the data they need from an Application Programming Interface. Compared to REST, GraphQL is more efficient, as it returns all requested data after one query instead of multiple.
Webhooks
Webhooks are not traditional APIs but serve as event-driven mechanisms that notify systems when something specific events occur. The most used application automates workflows and sends instant updates or messages to users without the need of polling.
What is Application Programming Interface Integration?
API integration is the process of connecting software applications using API. For instance, linking a company’s internal software with external tools like payment gateways. This allows real-time data exchange, improves management, and reduces human error.
