What is API Integration?

API integration is the process of connecting two or more different software applications to allow them to work together. API (Application Programming Interface), which sets the rules and protocols that enable various programs to communicate with each other.

You can say that an API is a messenger that takes requests and tells a system what to do, then returns the response. API integration connects these messages across different systems, ensuring they can share information and functions smoothly.

By connecting different apps and services, API Integration helps businesses automate processes, improve efficiency, and offer a more unified user experience.

How does it work?

Here is how it works:

• Identify Applications: Identify the systems or applications to be connected. Ensure they support compatible API protocols for smooth communication.

• Access API Documentation: Review the API documentation for each application. Understand how it works. Check endpoint details, request formats, and data transfer methods.
• Set Up Data Exchange: Configure how data will be exchanged between systems. Use methods like RPC or REST. Select an integration architecture, such as RESTful API or SOAP.
• API Request/Call: The client application sends an API request to the server. This is typically done using HTTP or another supported protocol.
• Processing: The server processes the incoming request. It follows predefined logic in the API documentation and protocol standards.
• Response: The server responds to the client. The response may include data, a status code, or an error message. This completes the data transfer.
• Test and Launch: Thoroughly test the connection before going live. Ensure all API requests, responses, and data transfers function as expected. Use your chosen architecture, like REST or RPC.
