Is API same as Web application?
API is an interface that exposes an application's data to outside software, whereas web applications are one type of API with stricter requirements. These requirements include network communication, SOAP as the primary protocol, and less accessibility for the public.
The biggest difference between an API (Application Programming Interface) and an App (short for application) is how each impacts the user. Both offer some form of connectivity, but while APIs are intended to be used by software applications, software applications themselves are intended to be used by humans.
APIs and web services are both ways for applications to exchange data. However, API and web services testing are different endeavors. To efficiently test each component, understand how it fits within the blueprint of the application.
APIs work only on-premises. APIs expose programmatic functionality. APIs work only in the cloud. Web apps expose programmatic functionality.
You could have a website, a mobile app, and a mobile web app accessing the same data using the same API, without needing to have a backend for each app implementation.
API is actually some kind of interface which is having a set of functions. These set of functions will allow programmers to acquire some specific features or the data of an application. Web API is an API as the name suggests, it can be accessed over the web using the HTTP protocol.
Yes, there's overlap between the two: all web services are APIs, but not all APIs are web services. Both web services and APIs are — at their core — very useful and very much used today.
There are four principal types of API commonly used in web-based applications: public, partner, private and composite. In this context, the API "type" indicates the intended scope of use.
They help you out by providing developers with an API, or application programming interfaces. There are more than 16,000 APIs out there, and they can be helpful in gathering useful data from sites to use for your own applications. But not every site has them.
Web service is used for REST, SOAP, and XML-RPC for communication, while API is used for any style of communication. Web service supports only HTTP protocol, whereas API supports HTTP/HTTPS protocol. Web service supports XML, while API supports XML and JSON. All Web services are APIs, but all APIs are not web services.
Is rest an API or web service?
A REST API (also known as RESTful API) is an application programming interface (API or web API) that conforms to the constraints of REST architectural style and allows for interaction with RESTful web services. REST stands for representational state transfer and was created by computer scientist Roy Fielding.
Web service is used to communicate between two machines on a network. Web API is used as an interface between two different applications for communicating with each other. It uses HTML requests that can be compressed, but XML data cannot be compressed. Data can be compressed.
API testing can be one of the most challenging parts of software and QA testing because APIs can be complicated, they are often based on protocols and standards that we often do no encounter in other kinds of testing.

SOAP is a protocol, whereas REST is an architectural style
An API is designed to expose certain aspects of an application's business logic on a server, and SOAP uses a service interface to do this while REST uses URIs.
If you want an app for your business, the likelihood is you'll need to develop an API at some point. The key is knowing what you want from it, understanding its role in the process and making sure your developer has the information they need to develop a creative, effective and efficient app around it.
To answer your question, yes it is normal to have several microservices (small APIs) working together in a solution.
In a few cases there may be a different endpoint for mobile or pass in a flag because it will display less data (because of screen size) or whatever, but in general, yeah, they usually use the same backend.
Often, an API is considered a backend "component". And, for instance, a database can also be treated as another backend component. The APIs you are likely referring to here are web APIs, so could be considered as backend components.
A dedicated REST API client (such as Postman) provides a convenient environment for building and testing requests. You can also send simple REST API requests directly from the address bar of a web browser.
What are 3 most common APIs?
There are also three common types of API architectures: REST, a collection of guidelines for lightweight, scalable web APIs. SOAP, a stricter protocol for more secure APIs. RPC, a protocol for invoking processes that can be written with XML (XML-RPC) or JSON (JSON-RPC).
Google APIs are application programming interfaces (APIs) developed by Google which allow communication with Google Services and their integration to other services. Examples of these include Search, Gmail, Translate or Google Maps.
The Chrome Management API is a suite of services that allows administrators to programmatically view, manage, and get insights about policies and usage of ChromeOS devices and Chrome browsers in their organization.

API stands for Application Programming Interface. In the context of APIs, the word Application refers to any software with a distinct function. Interface can be thought of as a contract of service between two applications. This contract defines how the two communicate with each other using requests and responses.
