To check the coronavirus inoculation status of an individual, the Co-WIN portal has developed a new API called ‘Know Your Customer’s/Client’s Vaccination Status’, the Indian health ministry said on September 10, 2021.

The ministry of health and family welfare (MoHFW) informed that to use the application program interface (API), the person needs to enter his or her contact number and name after which they would receive a One Time Password (OTP) which they have to enter.

In return, Co-WIN will send a response to the verifying entity on the person’s status of inoculation, which will be as follows - 0 - Person is not vaccinated, 1 - Person is partially vaccinated, or 2 - Person is fully vaccinated

This response will be signed digitally and can be shared instantly with the verifying entity.

This can be useful in situations where a person does not need to see the certificate in full and would just need to know whether an individual has been immunised or not, the statement said.

A real-life instance could be when at the time of booking a railway ticket, a person will fill in the necessary details for buying the ticket and if needed, the concerned person will also get the inoculations status in the same transaction, with the due consent of the individual, the ministry added.

The ministry further informed that the KYC-VS will avail all such use cases and more. It is both consent-based and privacy-preserving.

In addition to that, to get quick integration and faster adoption, the Co-WIN Team has prepared a webpage with the API, which may be embedded in any system. This will permit seamless integration with any system in no time.

“Besides the use cases pointed out, this service may be utilised by any service provider, private or public, for whom verifying an individual’s vaccination status is critical for facilitating a service requested,” it said.

Presently, Co-WIN is already issuing a digitally verifiable certificate as proof of inoculation for each inoculated person.

This certificate can be saved on a digital device (smartphone, tablet, laptop, etc.) or stored in Digi Locker from where it can be digitally transferred as and when required as proof of inoculation.

Therefore, the ministry stated, there is a need to enable an Aadhaar like authentication service for the status of inoculation through Co-WIN.

“To take care of these cases and others that may come up, Co-WIN has developed a new API called ‘Know Your Customer's/Client's Vaccination Status’ or KYC-VS,” the ministry stated.

More than 72 crore vaccine doses have been administered since the nationwide vaccination drive against COVID-19 was flagged off on January 16 this year by Prime Minister Narendra Modi.
