Q & A
What is a REST API and where is it commonly used?
-A REST API is a type of web service that uses HTTP requests to access and use data. It is commonly used for web-based applications, mobile apps, and websites, particularly for creating, reading, updating, and deleting operations.
What are the advantages of using REST API?
-REST APIs are highly scalable, stateless, and can use different data formats like JSON, XML, and HTML. They are good for web-based applications and can scale to a very high level.
What are the disadvantages of REST API?
-REST APIs lack built-in security, have less effective error handling, and can have some bandwidth overhead.
What is gRPC and in which type of applications is it typically used?
-gRPC is a high-performance RPC framework based on HTTP/2, and it is typically used in streaming and gaming applications due to its efficient serialization and low latency.
What are the benefits of using gRPC?
-gRPC offers fast performance and very low latency due to its bidirectional communication. It is suitable for applications where speed is critical.
What is the main drawback of using gRPC?
-The main drawback of using gRPC is that debugging can be complex and requires a higher level of expertise.
What is GraphQL and how does it benefit social media applications?
-GraphQL is a query language for APIs and a runtime for executing those queries against your data. It allows clients to request exactly the data they need, which is beneficial for social media applications where dynamic data is crucial for user engagement.
What are the advantages of GraphQL in API design?
-GraphQL allows for more efficient data retrieval as it provides only the required data, supports real-time updates, and is good for data-heavy applications.
What are the potential issues with using GraphQL?
-GraphQL can face issues when queries become large and complex. It also lacks built-in caching, which requires additional considerations.
What is WebSocket and in which context is it commonly used?
-WebSocket is a protocol providing full-duplex communication channels over a single TCP connection. It is commonly used in live trading and stock applications where continuous connection and low latency are required.
What are the benefits of using WebSocket?
-WebSocket provides a continuous connection with low latency, making it ideal for real-time applications such as live trading or chat systems.
What are the challenges associated with using WebSocket?
-WebSocket can have security issues, and developers need to be careful about implementing proper security measures.
What is SOAP and in which industries is it commonly used?
-SOAP is a protocol for exchanging structured information in the implementation of web services in computer networks. It is commonly used in enterprise, financial, banking, and government sectors due to its security and reliability.
What are the advantages of using SOAP?
-SOAP is secure, has robust error handling, and maintains transaction integrity, which is crucial for financial transactions and enterprise-level applications.
What are the disadvantages of using SOAP?
-SOAP is considered heavy and has high overhead due to its XML-based nature, which includes complex structures like envelopes and bodies.

🌐 Overview of API Protocols
This paragraph introduces the importance of API protocols in enhancing application performance, scalability, and user experience. It emphasizes the need to choose the right protocol for different applications and briefly mentions five top API protocols that are essential to know. The paragraph highlights REST API as the first protocol, suitable for web-based applications, mobile apps, and websites, using HTTP for data transfer and supporting various data formats like JSON, XML, and HTML. It points out the advantages of REST API, such as high scalability and statelessness, but also its drawbacks, including the lack of built-in security, less effective error handling, and potential bandwidth overhead.
📡 Deep Dive into Specific API Protocols
The second paragraph delves into the specifics of different API protocols. It starts with gRPC, ideal for streaming and gaming applications due to its low latency and fast performance, utilizing HTTP2 and efficient serialization. The paragraph then discusses GraphQL, which is beneficial for social media applications like Facebook and Instagram, allowing clients to request specific data, thus providing dynamic and tailored responses. It mentions WebSockets, suited for live trading and stock applications due to its continuous connection over a single TCP connection, but cautions about potential security issues. Lastly, it touches upon SOAP, which, despite being less popular, is still used in financial and government sectors for its security and reliability, although it is considered heavy and complex due to its XML-based nature.

Hello friends welcome to clarify and
decode let's have a quick and
comprehensive guide on API protocols
their use cases advantages
disadvantages as we know in today's
world choosing the right API protocol
can transform your application's
performance scalability and user
experience each protocol has its own
strengths and demerits so let's explore
the top AP protocols at least these five
are a must and also widely asked in the
interviews so the first one is rest
API whenever you get the term rest API
think in terms of websites it is good
for websites highly scalable
websites so it's based on web it uses
HTTP for data transfer and it can have
different formats like Json XML
HTML as I said it's good for web based
application websites just think of
websites even mobile
apps and in terms of websites it's the
back end the
microservices create read update
delete fine so as you know the pros are
you can scale your websites to an
infinite not an infinite but to to a
very high level as it is scalable and
stateless what are its cons there's no
built-in security for it you have to
device that the error handling is not so
good and it has some bandwidth usage
some
overheads let's go to the second one
grpc Google remote procedure
calls when you get this think in terms
of streaming and gaming
just relate grpc remote procedure calls
to any streaming or gaming application
then you can device your
answer it is based on
http2 and it has good serialization
Concepts as I said use cases gaming
streaming even chatting systems as slack
definitely it is Fast and the latency is
very very low
performance and that too because it's
bir
directional cons a slight disadvantage
the debugging is not so simple it
requires some expert level to understand
how to go about it third graph ql
whenever you get it think in terms of
social media Facebook
Instagram why because it gives you a
response that is based on the
client which specifies it so it can vary
whenever we have a large amount of
content you can have a query language to
get as per your
requests graph ql just keep in your mind
social media apps in an interview when
you asked we are designing a social
media app design next Instagram always
mention graph ql
okay because it gives Dynamic datas
right it's good for data applications
social media you want to have it data R
to attract the
users
fine
Pros as I told only required data so
it's fast and we can get realtime
updates disadvantages when the queries
get bigger and more complex it is not so
so good there's no inbuilt caching you
have to think about
it fine web sockets the fourth one
related to live trading
stocks why because we have a duplex
communication over the single TCP
connection lightweight we have
continuous connection that's why it's
reflecting in the so stocks so try to
think it in this way what features does
a stock trading app have continuous
connection latency should be very
low cons security issues not so well we
have to be careful about
this now come the one which many of us
had started not the oldest but been
there for a long time so simple object
access protocol it's declining a bit
some organizations are shifting but many
of the Financial payment government
related stuffs is built on soap some
people are STI still going through it
because of the
dependencies and it's not too bad it's
XML based different protocols it can
handle sttp CP
SMTP Pros secure it's like a lock
handling is very good the error handling
and whenever we have payments
transactional kind of things the
Integrity is is very good it's vled very
well as I said the use cases Enterprise
Financial Bank government payments cons
it is heavy High overhead a lot of XML
related stuffs envelops body a lot of
things so it's
complex but you should know about
it fine I hope you enjoyed this
session let's meet in the next session
thank you guys
