APIs And Real Estate Websites

Applications and websites have hundreds of features and if a developer wants to write code for every single one of them, it will take years for an app to be ready. And let’s not even talk about all the debugging and troubleshooting. Mostly, developers use libraries in which multiple codes are already up for grabs.  Most of these codes may need revising and some may be impractical. That’s why most developers use APIs to take care of their coding.

Now, let’s see what an API actually is and how it benefits my Real Estate website:

What is an API

An API or Application Programming Interface is basically a restaurant menu for developers.

They can choose from a list of features on this menu without worrying about the coding behind it. 

This means saving a lot of coding time, especially for monotonous and small works and it doesn’t end there. 

You can use it from a software/service provider and embed their services into your website or application.

If I need to show the map on my website, I don’t need to write so many codes for it. I simply use the API from a map service provider such as API. 

Some APIs are free of charge but even if they come with a price tag, it is often nothing compared to the time and cost of coding. 

In addition, you won’t have to worry about updating codes for everything on a website or application. Remember the restaurant menu? The chef will take care of everything.
