For example, the company Stripe began as an API with just seven lines of code. The company has since partnered with many of the biggest enterprises in the world, diversified to offer loans and corporate cards, and was recently valued at USD 36 billion (link resides outside ibm.com). API Gateway provides a comprehensive platform for managing, delivering, and securing APIs. It provides integration, acceleration, governance, and security for Web API and SOA-based systems. In this approach, the server assigns a unique generated value to a first-time client. Whenever the client tries to access resources, it uses the unique API key to verify itself.
You are probably excited to start actually doing some fun things with specific APIs, so let’s go! Next up, we’ll look at manipulating documents with the Document Object Model (DOM). We already discussed events earlier on in the course in our Introduction to events article, which looks in detail at what client-side web events are and how they are used in your code. If you are not already familiar with how client-side web API events work, you should go and read this article first before continuing. The audio starts in the source, which is then connected to the gain node so the audio’s volume can be adjusted.
Examples of web API
Apple’s iOS operating system provides a large number of APIs—as every other operating system does—to make this easier on you. Donations to freeCodeCamp go toward our education initiatives, and help pay for servers, services, and staff. REST APIs are stateless and can be used for separation of concerns between the client and server. An API (Application api explanation Programming Interface) serves as a middleware that lets you channel data between software products. In this article, I will explain what APIs are, why you need them, and we’ll dive into API specifications, documentation, and more. A client-side web API is a programmatic interface helps to extend functionality within a web browser or other HTTP client.
One great place to start using APIs is to customize your interaction with your customer relationship management (CRM) platform. Some providers allow users to develop custom tools, manipulate their data, or customize their page layouts — and APIs will let you do it all. As an example, Salesforce takes an API-first approach when building features on its platform.

Suppose one of the company’s partners develops an app that helps people find books on bookstore shelves. This improved experience brings more shoppers to the bookstore—the distributor’s customer—and extends an existing revenue channel. This allows third parties to develop apps that interact with your API and can be a source for innovation.
This integration is called “seamless,” as you never have a clue when a software role is passed from one application to another. This means that an API that returns JSON can be accessed by an application written in Java, Ruby, Python, JS, PHP, etc. This makes APIs developer-friendly, highly scalable, and platform-independent.

Even so, the foundational principles behind REST aren’t likely to disappear for a very long time. An API designer is a standards-aware tool that supports the creation of the API specification. Modern APIs focus their contracts primarily on communication—the Creation, Reading, Updating, and Deleting of data (or CRUD for short). CRUD operations are commonly (but not always) implemented using a set of architectural principles known as REST (Representational State Transfer), which describes how web-based technologies should be used.
