Let's pay him back by watching all the advertises on his videos, because that's the only way for him to make money

[@RaghavPal]

Thanks for your kind message

[@theweirdclub3945]

Loved your comment buddy

[@prachimuddapur]

It's so hard to make content simple. And impart that knowledge. Amazing!

[@RaghavPal]

So happy and humbled to see this message

[@imranshaikh115]

You put lot information in a very small video that is not an easy task for someone. It requires lot of skills and experience to make this kind of clear and crystal explanation about one confusion topic so anybody could understand in an easy manner. Thanks a lot for sharing very beautiful information. God may increase your knowledge

[@RaghavPal]

You're welcome Imran. Humbled by your message

[@sounakdas1063]

I also agree

[@harithav9505]

I Agree too..this is clear to have a basic idea of what's API. ThnQ Sir :)

[@user-uj1we7yv6v]

Really I too agree..thanks a lot

[@WolfGr33d]

"API enables communication between different applications" Thank you for being the first person to give an understandable explanation. I kept running into video after video giving vague descriptions of what an API does by using the Waiter and Chef analogy, without ever explaining they were representing applications.

[@RaghavPal]

Hi, glad to know this helped

[@Galaxy2431]

A much simpler way to understand what an API is, imagine you login to your Bank and do all the activities there - wire funds to another account, transfer, view balances, search a transaction by a specific amount or date, etc. This is User Interface, or UI. Now imagine you are a big company and have hundreds or thousands of daily Bank transactions. Inputting, handling and managing them manually would be a herculean task, very time consuming, would need a lot of people to manage these tasks manually, hence costly, as well as will be prone to error when you want to bring these bank transactions to your company's accounting ledger, like an ERP system. So, to facilitate this, most Banks provide secure digital interface with exactly same feature as you can perform via a UI. This digital feature is what is called an API. More appropriately, we will say that such and such features are implemented or exposed by a specific application (in our example the Bank) via APIs.

[@surabhisharma6608]

This is one topic which has so much information available on the internet including on youtube and yet i find myself continuing to come back to search for it again and again because something stays amiss. Thank you for this wonderful video and must I say that your style of speaking is very soothing and genuine. No flamboyance, only pure knowledge. You keep it real. Thanks.

[@RaghavPal]

[@RaghavPal]

Thanks for watching Gaurav

[@RaterisimoCBA]

Very simple presentation and perfect example as well. Subscribed ! Also an API maybe used if you don't want to create a functionality from scratch because it already exists (LOGIN for example) so you might want to use OAuth or some other login service that already exists and handles security protocols, etc for you without having to worry about encryption, data security , etc. So using an API can save you some time as a developer and complications in your project. :)

[@RaghavPal]

yes, well said

[@AnushR27]

Thankyou Sir for this very clear explanation of an API with examples :)
