Free api for testing

Building an API is fun, right? In this article, I will explain what APIs are, why you need them, and we'll dive into API specifications, documentation, and more. Programming is made simpler by using APIs to abstract away certain implementations, and expose actions or endpoints to developers who need to consume the endpoints when building applications. But APIs can get pretty complex depending on the application's code base and use cases. This means that testing your API endpoints might be a tricky process after developing them. Fortunately, there are amazing tools out there that I will share to help you test your APIs efficiently.

An API (Application Programming Interface) serves as a middleware that lets you channel data between software products. You can use it to define requests that have been made, handle business logic, the and manage data formats that should be used and the conventions to adhere to when building software products. Types of APIs There are three main types of APIs, which are: • Private • Public/Partner • External Private APIs These are APIs builts solely for use within an organization. They are classified as an in-house application for employees to automate business processes and delivery. Public/Partner APIs These are APIs that are openly promoted but available for known developers or...

A public API, also known as an external API, is a type of application programming interface that allows developers to access specific features and data of a software application or service. It is "public" in the sense that it is made available to third-party developers and is not limited to internal use by the organization that created the API. Public APIs are made available to anyone who wants to use them and typically do not need any special permission or authentication to access them. Developers can use public APIs to build new applications, enhance existing ones, or integrate different software systems. In this article, we will be discussing the types of public APIs, their benefit to developers, and public APIs that you can use in your projects. Types of Public APIs There are different types of APIs that developers can use to access data and features provided by online services. It's like borrowing someone's tool to help you do your job more easily. Here are the main types: Representational State Transfer (REST) APIs These are very popular and easy-to-use APIs which use HTTP requests to get or change data. An example is the Twitter API and some of the ones mentioned in this article. Simple Object Access Protocol (SOAP) APIs These APIs are more complex but have superpowers for security and advanced features. These web-based APIs use the XML data format to exchange data between applications. A popular example is Amazon Web Services (AWS) API. GraphQL This API can be more...

In a world where static websites and apps increasingly depend on separately maintained APIs, it can be hard to figure out how they work by just playing around in the browser. So how can we use Postman to both test our existing APIs and understand how they work? • • • • • • • • What is Postman? And it’s not just for testing. The beauty is that this can be used for many aspects of working with APIs for many different members of the team. Maybe a Project Manager wants to verify that things work or might find it easier to make a change straight with the API, or a QA Engineer needs to make sure everything still works, or a developer wants to actively make changes while working on the API itself. The best part about it – Postman provides collaboration features. The free tier includes exporting and importing collections of saved API requests as well as creating shared links. If you're part of a team, they have paid tiers that allow you to sync up your collections to make sure everyone has the most recent and up to date collection. What are we going to build / learn? We’re going to walk through two different example APIs to cover the concepts of Postman. First, we’ll walk through some simple HTTP requests with a We’ll then use the Yoda Translator API for one part to demonstrate how to make specific HTTP requests. Once we understand how the basics work, we’ll use the Part 0: Getting set up with Postman Before we get started, you’ll need Get Postman: Once downloaded, go through the ...
