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
