This resource is an application that acts as an intermediary to transmit information. At first it may seem like a complicated concept, especially without some context, but we are going to use this post to explain exactly what an API is and how it can be used to build a website.
What is an API?
The acronym API stands for Application Programming Interface. An API lets an application extract information about a type of software and use it to carry out some kind of data analysis.
A API endpoint is the destination where it will be published, as requested by the website owner. It is essential for any online space to work properly, since that is the only way to create secure endpoints; otherwise, we will not be able to use this valuable and simple resource.
Some well-known APIs in use today are the following:
- Twitter mentions. If you want to display tweets on your website, including a link to Twitter, you need to use the Twitter API.
- Embedding videos from YouTube. When you click on a video with the left mouse button, you need to choose the copy embed code option, which means you are requesting the use of the YouTube API.
Why should you use an API?
When an API is created, companies give external developers the option to build applications capable of improving the use of the main platform. This way, a company can make its system dependent on its API data, which can generate a stream of additional revenue.
How do you use an API?
As we said earlier, the core value of an API lies in knowing what information is available and how it can be accessed. If you want to know what an API could do for your company, ask a developer to analyze with you the use of a potential API.
If you add an API's resource URL to the backend of your own website, it will return the information you had requested to your frontend. Always bear in mind, however, that to be able to use the official API created by a developer, you must know the key associated with it. This key indicates that a website's application programming interface can be used. You could say that an API key is like the membership associated with it within a programmer's community.
It should also be clear that an API key does not give the developer the ability to access the customer's personal information.
With all this, we now know the main meaning of API and how it can be used in website design and development.
