What is an API?

Definition

An API is essentially a messenger that takes requests from one application, tells another application what you want, and then brings back the response. It defines the methods, data formats, and conventions that applications use to communicate, making it possible for your CRM to talk to your email platform, or your website to connect with your payment processor.

How APIs Work

APIs operate on a simple request-response model. When you want data or action from another system, your application sends a request to that system's API with specific parameters. The API processes this request, performs the necessary operations, and sends back a response with the requested data or confirmation that the action was completed. This all happens in the background, usually within seconds.

Types of APIs

1. REST APIs - The most common type, using standard web protocols to exchange data in formats like JSON
2. SOAP APIs - More structured and secure, often used in enterprise environments with strict requirements
3. GraphQL APIs - Allow you to request exactly the data you need, making them efficient for complex applications
4. Webhook APIs - Push data to your system automatically when specific events occur, rather than waiting for requests
