Co-WIN has developed a new Application programming interface called ‘Know Your Customer’s or Client’s Vaccination Status – KYC-VS. This will enable entities to check an individual’s status of vaccination through CoWIN.

• 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. 
•  If the response of Co-WIN – 0 – means Person is not vaccinated, 1 – Person is partially vaccinated and 2 – Person is fully vaccinated.
• This response will be digitally signed and can be shared instantly with the verifying entity.

Union Health Ministry said, over 72 crore vaccine doses have been administered since the vaccination campaign against COVID-19 was flagged off on 16th January 16 this year. To provide a proof of vaccination for each of these individuals, Co-WIN is already issuing a digitally verifiable certificate. This certificate can be saved on a digital device or stored in Digi Locker from where it can be digitally shared as and when required as a proof of vaccination.
