Hello one Welcome.
Thank you so much for joining me today.
I do appreciate your time in this lecture.
You learn what an API is.
I will also show you an illustration of an API.
What is a P and napi stands for application programming interface.
This is this set of programming instructions and standards for assessing a web based software application.
So a software company can release its API to plug to the public so other software developers can design
products that are powered by its services.
For example Amazon has this API.
Pay Pal has a P E B also has API of equal marce companies and other related companies have a.
What the API does.
It allows third party websites to post direct links to.
For example blogs on Amazon and also people so where you have companies that add paper buttons.
If you go to shop on an e-commerce site you may see a paypal button that is on use in a paper API.
Similarly on Amazon you may go to a website and see an Amazon link.
That also is done using an E P I saw an API stands for application programming interface.
It's a set of program instructions and standards for assessing a web software application or web tool.
This is an illustration of a transaction that happens on an e-commerce site.
So this is the person making the purchase.
So are male or female.
This is a website.
For example I wanted a camera from ebay so I had gone to eBay and click on the camera I want and then
click on the buy button.
So when you click on the buy button what happens is your credit card information is passed on to the
VS the card company.
All this this happens behind the scene so this is possible because of the use of this API.
So this is b software talks to Vincent Kompany softly behind the scenes.
So the B software passes on your information and to the A Company.
This company checks your information is corette passes the information back to you bnc Good to go and
then your transaction is confirmed as paid.
And then you get your goods.
So the pib a patient program in interphase allows the communication between two companies behind the
scene so you as the customer doesn't see what goes on behind the scene what goes on happened between
eab because the company is done behind the scene so you dont see this interface behind the scene or
you see that you click on pay your payment details are being processed and this is how they've been
processed past to be from eBay to the card company.
The card company checks to make sure everything is good to go passes the information back.
Will you be good to go.
And then eBay confirms your transaction.
And then you ship ship your items to you.
Another example of an API at work is when for example you buy a movie ticket online and enter your credit
card details or information.
What happens.
The movie ticket website.
So for example this website I am on.
What Ill do it will be it will use an API to send your credit card information to a remote application
that verifies the information you are put in.
This correct payment is confirm the application then sends it response back to the movie website.
For example this Web site to say everything's okay.
Checked in all right.
You can be issued a ticket.
So what happens is that the actual customer doesn't see that interface between the transaction from
this movie website to any remote company.
So for example credit card company that checks information so all that happens behind the scene.
You as a customer you don't see that interface or you see is the current site you are on in this lecture.
You learn to what an API is and also we showed you a couple of illustrations on how API works.
Thank you so much for your time.
I hope the lecture has been useful.
