Hello and welcome.
In this heat you are going to give you a very brief introduction to a piano.
What does the API stand for.
It is an acronym that stands for application programming interface API is an intermediary software that
allows two applications to talk to each other.
Each time you use an app like Facebook or you send an instant message and you check the weather on your
phone you are actually interacting via an API.
Eyes are responsible for a lot of interaction and communication.
So let's take a look at some example.
Most of the social happy eyes.
So we got things like Facebook Twitter Google Talk Foursquare soundcloud.
These are just some examples of social epee.
We've also got visual API is Examples include Google Maps YouTube.
Q Where Pinterest flicker.
When I use an application on your mobile phone for example my application connects to the Internet and
sends data to a server server then retrieved that data into pruett's it performs the necessary actions
and sends it back to your phone.
The API acts as an intermediary behind the scene that allows the communication to flow between applications.
So the API in we act as the messenger that takes information to the server and once the server into
Prezi formation sends it back via the API the API then sends it back to the phone and the data is presented
in the way in the format that the form can understand.
So the key benefit of the API.
Here it allows for communication to happen.
Another illustration of how the API works is try a restaurant for example.
Imagine you are sitting at or standing at a restaurant with a menu of your choice to order from the
kitchen is the part of the system that will prepare your order.
The API is in the middle.
The API will be the waiter or the messenger that will communicate your order to the kitchen.
Once your order has been prepared by the kitchen be happy all the waiter take sick order and present
it to him.
So the API takes your request or your order tells the kitchen which is the system.
What to do.
Then the waiter delivers the response back to you.
In this case the food is a response.
Let's take a look at a real life kpi in action.
You may be familiar with the process of searching for flights online just like a restaurant you have
a variety of options to choose from.
For example I am on this site called Google Flight say I want to go somewhere different options I select
where I want to go put all the relevant details and then hit the search button.
Here is a certain button that you will hit.
Let me do that so for example I say I want to go somewhere.
I choose a date I have chosen a date and I just choose the airport.
I see UK as London metro.
See I'm going to New York.
I say New York.
Put that there.
Okay so is giving me all the flight details.
Looked through to see whatever I need to do.
So the information we're getting here relating to the flight.
Details He is possible because of a API an API seats in the background.
So each time we do a search we are physically contacting the airline website or the airlines database
via an API.
The API is the intermediary software that allows this communication to take place.
So all those data get him back from the search is made possible because of BP.
It is a AP Ida lousy communication between this site and be outwalk airline site that contains the data.
So this is basically how a PDA used a lot of applications and programs and other things that relate
to data and information.
Thanks for watching by phone.
