An API (Application Programming Interface) is a set of rules that allows applications to communicate with one another, exchange data, or perform operations. The MDN describes it as an interface between software that provides capabilities and software that uses them.
How does an API work?
An application sends a request to an endpoint. The API validates it and returns a response, often in JSON. In Web APIs, communication often uses HTTP.
What is an API used for?
It is used to integrate software and automate processes. It can synchronize an e-commerce platform with an ERP system, send data to a CRM, process payments, or use external services.
Key Features
Interface defined
The documentation lists endpoints, accepted data, and responses.
Security
It may require authentication and permissions to control access.
Reuse
The same API can serve websites, applications, and internal systems.
Benefits of APIs
They facilitate integrations, reduce manual tasks, and enable different systems to work together.
API vs. REST API
API is the general concept. REST is an architectural style. A REST API is a type of API, typically based on HTTP. Not all APIs are RESTful.
Examples of Use
In an e-commerce platform, an API can update inventory levels from the ERP and send orders to the billing system. In Headless Commerce, APIs connect the front end to the e-commerce engine.
Who should use APIs?
Companies that need to exchange data between applications, automate processes, or integrate services.
Frequently Asked Questions About APIs
What is an API key?
It is a credential used by some APIs to identify or authorize the requester.
What is an endpoint?
It is an API endpoint used to access a resource or operation.
What is a REST API?
It is an API designed according to REST principles.
Is an API secure?
That may be the case when there are appropriate mechanisms for authentication, authorization, and data protection.
Are APIs and webhooks the same thing?
No. An API typically involves a request. With a webhook, a system sends a notification when an event occurs.
