How To Use An API The Complete Guide Simple API Example


It set the standard for machine-readable files that interface with RESTful services. The files produce documentation automatically that syncs with libraries and source code depositories. This requires providing standard interfaces so APIs can be accessed and used in any appropriate programming context with What is API minimum knowledge. If the standard is defined, implemented, and widely adopted, it can produce APIs that are accessible to any programming tool—without requiring programmers to have prior knowledge of the peculiarities of specific APIs. REST APIs simplify and standardize communication between computers.

Peculiarities of using APIs

Given all of these benefits, it’s easy to see how APIs have become the building blocks of modern applications. But whether you’re a consumer or creator of public APIs (or both), care must be taken. The flipside to these benefits is that, by their very nature, APIs expose data to outsiders. The “responder” behind every API is the provider’s web server and/or database. This makes an organization’s APIs extremely attractive to attackers, not just for the data the APIs provide, but as potential entry points to other backend systems within an organization’s infrastructure.

Does an API have _______ Functionality?

What’s more, by sharing an API, you’ll build a network of users who rely on your API code and data. This encourages users to adopt other parts of your platform, expanding your customer base and increasing loyalty. Partner APIs are shared externally with business partners of the organization. Usually these are used for creating deep integrations, sharing sensitive information or functionality, or accomplishing things that each organization could not individually. For example, traffic app Waze uses APIs to exchange data with local government agencies and other partners about road closures, accidents, and other factors that impact traffic. Around 2010, some developers began using APIs to connect everyday objects—such as cameras, thermostats, speakers, microphones, and sensors—to the cloud.

  • These are ready-made, often free tools that help you structure your requests to APIs.
  • Application Programming Interface management is an important part of modern software development.
  • An enterprise that cultivates a business strategy that involves sharing its applications and data with other businesses will develop and offer a public API.
  • It should also be able to notify about how many “pages” of the data are left.

For example, maps API allows map information integration via websites, Android,iOS, etc. Any business can give similar access to their internal databases by using free or paid APIs. REST defines a set of functions like GET, PUT, DELETE, etc. that clients can use to access server data. API architecture is usually explained in terms of client and server. The application sending the request is called the client, and the application sending the response is called the server. So in the weather example, the bureau’s weather database is the server, and the mobile app is the client.

What are the Characteristics of an Effective API?

Neck, OAuth provides considerably better usability for the application users/developers than any other method. The range of API implementations can go far beyond SaaS-to-SaaS integrations, though. In more complex digital transformation scenarios, it is quite a common practice to use APIs to connect IoT platforms to a lightweight integration middleware like iPaaS, and then connect the latter to a legacy ESB.

She holds SANS GIAC Information Security Professional (GISP), GIAC Security Essentials (GSEC), and GIAC Security Fundamentals (GISF) certifications. Her bachelor’s degree from the University of Washington is in scientific and technical communication with an emphasis in computer science. She is the author of 18 technology books published by IDG Books, SAMS, QUE, and Alpha Books. A mental model is one of the hardest things for a leader to change, but it doesn’t have to be the most expensive. IDC projects that organizations will spend $6.8 trillion on digital transformation between 2020 and 2023. Large enterprises funding transformational programs can align their already budgeted spending with these new approaches.

What are REST APIs?

When a client logs in, an identity-management service provides the client with a JWT. The API has access to a public key or a secret that it uses to verify the token. For example, you may have heard of Java APIs or interfaces within classes that let objects talk to each other in the Java programming language. And new API technologies and styles continue to pop up today, like GraphQL and AsyncAPI to name a few. There are over 15,000 publicly available APIs, according to Programmable Web, plus many thousands of private APIs that companies use to expand their internal and external capabilities. The API is the interface that, like your helpful waiter, runs and delivers the data from the application you’re using to the airline’s systems over the Internet.
