Application Programming Interface (API) services are interfaces that show a program how to communicate with a system to access and/or modify the data contained within.
The method by which a piece of software (such as a mobile app) communicates with the functionality kept in the software’s backend is referred to in this article as an API Service (i.e., on the server or made available by a third party). Why need an Employee management system
Despite significant technical distinctions, we shall assume for this article that the APIs we cover are “web APIs,” that is, APIs offered through the HTTP/HTTPS protocol.
Take user authentication, arguably the most used API function, as an example. Your account registration is verified every time you use an online service or mobile app. The service provider or a third party using OAuth may be used for this authentication.
Almost always, user authentication is handled through an API. This is because the procedure necessitates checking the user’s information against a database before storing it.
The client-side interface alone cannot be used to register, nor would it make sense to do so. For the user to access secured or customized content on the front end, user registration data must be verified and kept on the backend.
Some applications enable “offline modes” by utilizing client-side storage. These programs store data in the device’s memory until the device reconnects to the internet and submits the data through API. Programming language for web development
API Services vs. API Microservices
The phrase “API microservice” refers to an API that communicates with a backend that uses the microservices architectural framework. Microservice architecture is a technique for creating programs that separate components into manageable, independent chunks. A single, isolated (or monolithic) application comprising all the components is an alternative.
Instead of being a part of a single, enormous application, microservices are housed in tiny, independent containers. This method’s benefit is that it enables considerably safer backend code modification.
This is so that you don’t have to edit and redeploy the complete application but just change one component. Consequently, you can quickly identify the component creating problems, making debugging considerably simpler.
The high reusability of the self-contained components is another advantage of the microservice concept. This is crucial to what we shall talk about next.
What is API as a Service?
In a recent piece, the well-known tech blog site TechCrunch referred to APIs as the upcoming big thing in SaaS. (SaaS). In essence, API as a Service is a software platform that enables customers to manage their customized APIs and third-party API interactions.
An API offers two essential components as a Service platform:
The capacity to create, test, and deploy one’s API services, as well as the capacity to integrate a program with external APIs
There are several types of third-party APIs. An application may use third-party APIs, such as Google Maps, payment processing services, and voice search APIs, in addition to the login example given above.
How to use Backendless as API as a Service
Backendless is an API as a Service platform that offers full-service application development. Microservice architecture is used in the construction of Backendless. Backendless’s built-in APIs can be utilized alone or jointly within an application. All Backendless APIs are available for all of our SDKs, including iOS, Android, and Flutter, as simple REST APIs.
