Transcripts
as a professional software developer, it's essential to understand the difference between
rest api vs web api vs soap. while all are formats that are interchangeable in many situations and
are used to communicate between different software systems, they have different architectures,
structures, and use cases in this video, lets explore and understand the key differences
between each one of them and when to use each one of them. so lets get started,
first off, what is rest api: well, rest stands for representational state transfer. rest api is
a web-based application programming interface that follows the rest architectural style
the primary purpose of rest is to provide an architecture for building web services that can
be consumed by various clients, including web, mobile, and desktop applications
rest is based on http, which is the standard protocol used for communication on the internet it
uses the http methods, including get, post, put, delete, etc., to perform various operations on the
resources each resource in rest is identified by a unique url, and the response is returned
in json or xml format one of the essential features of rest api is that it follows the
stateless client-server model this means that the server doesn't store any information about the
client's state between requests. instead, each request contains all the necessary information
required by the server to process the request. this architecture makes rest api scalable and
easy to maintain so, when to use rest api: frankly speaking, rest api is an excellent
choice when building web services that require a stateless, scalable, and easy-to-maintain
architecture. it's ideal for building applications that require crud operations, such as creating,
reading, updating, and deleting data. rest api is also suitable for building applications that
require real-time communication, such as chat applications and streaming services.
next up, what is web api: well, to state simply, web api is a broader term that encompasses all
types of apis that can be accessed over the internet. it includes rest api, soap, xml-rpc,
and many other types of apis. the primary purpose of web api is to provide a platform-independent
interface that can be used by various clients, including web, mobile, and desktop applications.
web api uses different protocols, including http, https, and tcp/ip,
to communicate between the clients and servers. unlike rest api, web api doesn't follow a specific
architecture or structure. instead, it can be designed using any technology or architecture,
depending on the requirements. one of the key features of web api is that it
provides a flexible interface that can be used by various clients. it allows developers to expose
various functionalities of the application, including crud operations, authentication,
authorization, and many others. this makes web api a powerful tool for building complex
applications that require a lot of integration and communication between different systems.
so, when to use web api: frankly speaking, web api is a better choice when building complex
applications that require integration with different systems and technologies.
web api provides a flexible interface that can be customized to meet the requirements
of various clients, including web, mobile, and desktop applications. web api is also
suitable for building applications that require authentication, authorization, and security.
next up, what is soap api: soap stands for simple object access protocol, which is a
messaging protocol used for exchanging structured data between different applications. soap api is a
web-based application programming interface that follows the soap messaging protocol. the primary
purpose of soap is to provide a standardized way to exchange data between applications,
regardless of the platform or programming language used. soap api uses xml as the format for sending
and receiving data, and it supports a wide range of data types, including text, numbers, dates, and
binary data. soap also supports multiple transport protocols, including http, smtp, and ftp. one of
the essential features of soap api is its ability to define a set of rules for exchanging messages
between applications. these rules are defined in the web services description language (wsdl),
which specifies the format of the soap message and the operations that can be performed on it.
another essential feature of soap api is its support for advanced security mechanisms,
including digital signatures and encryption. these security features ensure that data
exchanged between applications is secure and cannot be accessed by unauthorized users
so, when to use soap api: soap api is an excellent choice when building applications that require a
highly secure and reliable method of exchanging data between applications it is ideal for
enterprise-level applications that require complex data structures and business logic.
soap api is also suitable for building applications that require
advanced security features, such as digital signatures and encryption.
next, lets summarise the difference between rest api vs web api vs soap api: first,
rest api: - it follows the rest architectural style - it uses http methods (get, post, put,
delete) to perform operations on resources - it returns data in json or xml format only and
follows the stateless client-server model - it is suitable for simple applications,
particularly those that require crud operations and real-time communications
next, web api: - it doesn't follow any specific architecture or structure - it can use any
protocol or technology to communicate between clients and servers - it can use any data format,
including json, xml, csv, and many others, and further, can be stateful or stateless,
depending on the requirements - it is suitable for building complex applications that require
integration with different systems and technologies and lastly, soap api: - it uses
xml as its data format - it follows a specific set of rules and protocols for communication - it
requires a soap-specific protocol, such as wsdl or uddi, to describe the interface - it is suitable
for building enterprise-level applications that require robust security and reliability
