Let’s briefly talk about what we can do with it in a business context.
APIs can generate massive amounts of value both internally and eternally.
Managing and processing data is one of the crucial factors in business management, and every company has built IT systems.
As the size of the data is increasing exponentially, however, there is a limitation to cope with all the data through the traditional IT system.
In this sense, applying API can be a solution with better efficiency and security.
It can break down barriers between systems, which enables simplifying work processes, inter-cooperation between organizations and higher protection of data.
External merits of API are even fancier.
If a company open their API either publicly or with extra fees, it can provide new services and acquire potential customers to their side.
Customers can experience a higher level of services that weren’t available before.
By offering API services, third-party developers can build whole new kinds of products that even the companies had never thought of.
For example, Google Map, the most popular API among developers, wasn’t expected to draw that much effects at first.
By Applying those data to real estate and various other fields, developers brought much higher values and assets back to Google.
Nowadays the number of API is continuously increasing, and this trend will be ongoing or even more.
Now we can say that the implementation and management of API of a company is one of the critical factors for its competitive and strategic values.
So how to use API?To work with API, you need to get an authorized key first.
It’s for obtaining an authorized key to be connected with API.
API Providers, Youtube in this case, don’t merely provide their service without control.
To preserve this interface and manage the users, they offer a unique access key to each user.
With this, we can connect to the interface of the application.
Just like we connect to electricity by plugging the power cord into an electric outlet, we plug our server into the storage with this unique key.
And from that point, we can use the data and protocols of API.
So now let’s start with how to get the authorized key.
There is a very nice tutorial for getting the key.
If you’re a web developer, you can follow this tutorial step by step.
How to Create Your YouTube API CredentialsCreating your YouTube API Credentials is accomplished by performing to main stages: Stage I — Creating a Google OAuth…help.
aolonnetwork.
comIf you are to do some data analysis, you don’t need all these steps.
You follow the steps until number 9, and then choose ‘other’ instead of ‘web application.
’ There are two different types of clients on the developer console, and the access methods are different for each case.
Therefore if you try to get the key by ‘web application’ and ask for Oauth from your local computer, you could meet the error message like what I got.
So click ‘other’ option then you will get the client key and secret key.
Copy and paste them on your local computer.
The tuber package for Youtube APIIn R, there is tuber package which is made only for Youtube data analysis.
You can draw various data including the number of videos of a particular channel, the number of views, likes and comments on a video and so on.
To call this data in R, you need to install ‘tuber’ package first.
Then you ask Google for the authorization token.
install.
package(tuber)library(tuber)client_key = ''client_secret = ''yt_oauth(app_id = client_key, app_secret = client_secret)When you comment this code, a browser will pop up with some numbers allowing you to authorize the application.
If you check your local tool, R will already be waiting for the numbers so copy and Paste the serial numbers.
Now you finally get to be connected with Youtube API.
I will also introduce some of the functions that could be useful for analyzing Youtube data from tuber package.
get_all_channel_video_stats : This is the function for getting statistics on all the videos in a channel.
You need a channel_id to use this.
get_stats : This gives you statistics of a video with video_id.
The return values are the count of views, likes, dislikes, favorites, and comments.
get_video_details : This provides more specific information as the publish date of a video.
You can also get titles, descriptions, thumbnails, and categories.
get_all_comments : It gives you all the comments for a video so has great usage for text mining in respect of particular topics or channelslist_channel_activities : This returns a list of channel activity.
list_videos : It returns the most popular videos.
There are other useful API calls, so I recommend you to check them.
You can browse them from here.

comThere are plenty of APIs already but, a small number of them open publicly.
As data will directly transfer to the competitiveness in today’s world, I do understand companies’ intentions.
I believe, however, they shouldn’t neglect the potentials of sharing economy.
By making their internal data accessible, they will unleash the creativity of developers and data scientists all over the world to devise whole new uses for the data.
Just like what we have done with open sources over the last years.
