As the need to enable an Aadhaar like authentication service for the status of vaccination through Co-WIN was felt, Co-WIN has developed a new API called ‘Know Your Customer’s or Client’s Vaccination Status’ (KYC-VS). To use this API, an individual needs to enter his or her mobile number and name. Thereafter, they will get an OTP which they have to enter. In return, Co-WIN will send a response to the verifying entity on the individual’s status of vaccination, such as Person is not vaccinated, Person is partially vaccinated, and Person is fully vaccinated. This response will be digitally signed and can be shared instantly with the verifying entity, the Union Ministry of Health and Family Welfare (MoHFW) said.
“A real-life example could be when at the time of booking a railway ticket, an individual will input the necessary details for buying the ticket and if required, the concerned entity will also get the vaccination status in the same transaction, with the due consent of the individual,” it explained.
According to MoHFW, the KYC-VS will facilitate all such use cases and more. It is both consent-based and privacy-preserving. Additionally, to facilitate 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 allow for 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.
