Automate Co-WIN Vaccine appointment availability in your application

Co-WIN released new Public APIs to find vaccine availability and to download vaccine certificates. These APIs are available for use by all third-party applications as the Co-WIN website says.

Now developers can build new tools to find the vaccine appointments by district, by PIN code.

The government has issued new updates to Co-WIN Public APIs in which you will get delayed vaccine appointment availability data up to 30 mins. If you will implement it in your application, you will get 30 min old data. Also, the API Setu website says that these APIs are subject to a rate limit of 100 API calls per 5 minutes per IP.

The latest and real-time vaccine data only available on the Co-WIN and Arogya Setu platforms.
