Introduce what an API is and how it works
An API, or Application Programming Interface, is a set of instructions that tells programs how to interact with each other. In the case of our API, it tells web services what information to send and where to send it.
When you access an API, you are accessing its instructions or directions – hence the name “Application Programming Interface”. You can think of an API like a map with instructions on how to get somewhere. When the map says “turn right at the intersection”, that is the API.
The API we are building will allow other sites and services to access information directly from a business’s website. This data can then be used by that site to augment their own offerings – such as dynamic pricing based on availability, inventory or promotions.
There are a number of ways to interact with an API. The most common is by accessing it through the browser, using a technology called “JSON”.

Explain the benefits of using an API for businesses
Businesses can do more with the API. Businesses can create apps and websites, both using the API as a guide to provide users with information, instead of having users go to different web pages for all their needs. Businesses can integrate the API with their existing technology, reducing clutter and increasing efficiency. Businesses can share information with other businesses, creating a network that allows for businesses to interact freely.
Businesses can extend their reach and expand their capabilities. Businesses can utilize the API’s resources and make them their own.

The reason that “info plus commerce api” is in quotes is because it’s a blog post, and not an official statement or definition. A blog is a medium for people to express their own personal opinions and views on various subjects, though many are of the opinion that this medium is somehow less credible than an official document published by a government agency or other cultural institution.

Showcase a few popular APIs and how they’re used
The Facebook API serves as the primary API for Facebook, with over 2 billion users. It uses OAuth 2.0 to access the user’s data. The Twitter API works similarly to the Facebook API, but with a simpler process for users and only allowing developers to access public information about a user (as opposed to the full user data that Facebook allows). LinkedIn’s API is similar to the Facebook and Twitter APIs, but it is more niche. While Facebook and Twitter focus on users interacting with other users, LinkedIn focuses more on professional users. LinkedIn’s API is used for accessing information about businesses, jobs, and users. Amazon’s API supports over 400 of its own services, including Goodreads, IMDb, and Zappos. This enables users to access a variety of tasks on Amazon’s website through various other websites with the use of their API. The goal of this article is to give novice developers an idea of how each of these popular APIs work through a few examples. It will also provide insight into how they can be used in beginner projects.

Offer advice on choosing the right API for your business needs
First, businesses want to consider their customers and how the API will benefit them. Will it make accessing information simpler? Will it allow new ways for users to access information? Second, businesses should consider the functionality that is included in the API. Some APIs offer a simple user experience with limited functionality (as in the case of LinkedIn), while others offer a complex user experience that includes every possible feature (as in the case of Facebook). Finally, businesses should consider the cost of the API. Is the API cheap? Does it fit a business’s budget? Is it easy to maintain and update?
So, when thinking about how to select an API for your business, there are many questions that you must answer. To answer these questions, you need to understand how APIs are built and what they provide.
1. What is an API?
API stands for Application Programming Interface, and it is a way for one software application to interact with a different software application. For example, when you create an account on Facebook, Facebook’s API lets you post updates from within your own website. When you’re logged in to your email account, Mailchimp’s API lets you send out emails through any webmail or desktop app. APIs break down the wall between applications and make it easier for one system to interact with another.
2. What happens when you create an API?

Provide case studies of successful businesses that use APIs
These are the most popular APIs, but there are many more out there. By searching for “top APIs” you will be able to find a good list of other APIs that businesses can use. As for case studies, businesses can use a few different methods, and some will work better than others: a) A case study can include a company that has been in operation for a good amount of time and has been able to develop an extensive network of partnerships with other businesses, allowing them to provide services more quickly. Another option is to include companies who have just launched an API, allowing them to start their network from the beginning. b) A case study can also be written about an older business that has used its API for several years. This helps the reader to see how a company started from a very small network of services, and then they expanded. Most examples of businesses that use APIs are newer, so this option is rarer. c) Finally, a case study can be written about a business that is using an API to release information or provide services that weren’t available before, like offering faster services than other businesses.
Many businesses have begun using APIs to help create new profit streams or improve their existing products. While doing so can be difficult and costly, there are a lot of businesses that have used APIs successfully.
