The acronym API (short for Application Programming Interface) refers to a set of programming rules that allow an application to pull information from another service and use it both for its own purposes and to analyze that service’s data.
Put more simply, APIs let your services communicate with others without compromising your security. This is very important for working with your partners without wasting time and money. By developing cloud-native apps, you can share your data with customers and external users.
Real-world API examples
To make this more concrete, let’s take a simple example. Imagine you run an email marketing service. One of your customers doesn’t want to use your software’s sending interface but would rather integrate it into their own system. That’s where APIs come in: they let the customer integrate your service into their system and use your features.
All of this, of course, while maintaining maximum control, privacy and security.
Why use them
The reason to use them comes down to one word: simplification. By sharing this data, the service developer doesn’t have to write new code (which takes time). Even more importantly, sharing the data doesn’t “reveal” the source code of the application it comes from.
Security is also ensured by another factor. Generally, when an API is shared, a request must be made to access the data.
This makes it possible to check whether the requester is authorized and act accordingly to protect your privacy.
APIs in the business world
Beyond the benefits described above, it’s just as important to highlight how powerful APIs are in the business world. Sharing services between different sites makes it possible to integrate new features.
Above all, it lets businesses expand into new areas and markets while cutting development time and avoiding high costs.
