Get Available Slots using CoWIN APIs

In this post we will be looking into the CoWIN APIs which GoI has published during the covid period where the third party app can utilize the APIs to create there own app.

We used only few API from the public list and created a Spring boot application which will get me the list of all the available slots for either the old or young people based on their age on a given date and list of pincodes. 

You can refer to the government API from here: https://apisetu.gov.in/public/api/cowin#/

Also, you can find the github link for all these services and the application at the end of this post.
