The CoWIN website team offers multiple APIs for public use. Through this APIs, Web and App Developers are pulling the data and sharing to their users.
There have been instances of Indian Jugaad and deploying the APIs to bypass the system, and get quick access to vaccine slots.
To reduce such instances, CoWIN administrators have made few changes to the API data.
Co-WIN Public APIs to find appointment availability and to download vaccination certificates.
These APIs are available for use by all third-party applications.
The appointment availability data is cached and may be up to 30 minutes old.
Further, these APIs are subject to a rate limit of 100 API calls per 5 minutes per IP.
Please consider these points while using the APIs in your application.
2nd Dose eligible beneficiaries – CoWIN calculates the minimum gap required between the 1st dose and the 2nd dose and displays only the available vaccination centres after the 2nd dose eligibility date. This reduces the stress on the beneficiary. There is no need to see the vaccination centres if one is not eligible for the 2nd dose.
Two types of APIs are hosted by CoWIN team
01) CoWIN public APIs
02) CoWIN private APIs
User Authentication APIs

Private APIs: -
The APIs help any IT Developer to build apps which retrieve data as per the respective API function. This is a transparent method and the end user can be assured that the data is coming from an authentic source only.
Of course, if the IT Developer adds some more features to the final app, than the dynamics may change..
In the coming day, based on the feedback received by the users, more and more enhancements will be visible in the CoWIN App
