Introduction To API Products

A person exploring the APILayer marketplace

An API (Application Programming Interface) is a helpful technology that enables developers to build apps quickly using existing functionality and data. This way, developers don’t have to start from scratch to build a specific app. For example, if you’re looking to develop an app that provides current and future weather information to users, you can use a weather API product to source data for your app. Similarly, you can use a currency data API to create an app that provides real-time and historical exchange rates for different world currencies. Hence, API products accelerate the application development process and reduce costs.

What Is An API Product?

Before we discuss what an API product is, let’s first discuss what an API is.

An API refers to a set of functions and protocols that enable two applications to exchange data. In other words, it allows two different apps to interact and talk to each other. Additionally, an API is capable of accessing the features, data, and functionality of other apps and software. Most of us use an API on a daily basis. For instance, when we log in to Facebook or check weather conditions on our smartphones, we use an API.

API Product: An API product is simply an API that is available to other app developers for consumption, such as a SERP API, IP to geolocation API, weather API, and more. An API product is sometimes also defined as a set of APIs that work together in one single app to perform different operations.

How Do API Products Work?

If API products are made using REST, they support four HTTP methods:

  • GET: Enables users to retrieve data from a server

  • POST: Used to send data to the server

  • PUT: Enables users to modify/update a resource or resources

  • DELETE: Removes a resource or existing data from the server

Here is how an API works:

First, the receiving app initiates an API call or a request to retrieve data/information. This is done by sending a request to the web server via the API’s URI (Uniform Resource Identifier). Next, the API calls the web server of the other app or program. The server then sends the requested data or information. Finally, the API sends the data back to the receiving app that initiated the request.

If an API product is delivered as a bundle of APIs, it consists of both internal and external APIs. For example, if a restaurant uses an API product for their app that customers can use to place an order, the internal APIs will be used by the restaurant management to manage the menu, ordering of food, and payment processing. On the other hand, customers will use external APIs that help place an order or track delivery time.

What Are The Benefits Of Using API Products?

API products offer several benefits:

  • APIs speed up and improve the app development process, and reduce costs, as developers don’t have to create their own data sources for their apps

  • Add an additional security layer between business data and server

  • APIs enhance the automation processes of websites and web apps

  • Enable businesses to react efficiently to new opportunities

What Is An API Marketplace?

An API marketplace is essentially a platform that consists of several different types of API products in one place. In other words, API developers can use an API marketplace to monetize and sell their APIs. Additionally, app developers can also use an API marketplace easily to find their APIs and integrate them into their projects.

An API marketplace is like an e-commerce marketplace, such as Amazon, where sellers can list their products and consumers can order online. Similarly, an API marketplace connects APIs sellers and consumers. You can simply list your API products with their pricing details on an API marketplace, and other developers and businesses can buy them online. You can also offer a free plan to allow consumers to try and test the API features.
