The government opened the Application Programming Interface (API) of the Co-Win platform for third-party applications hoping that it would help people with useful data during the crucial vaccination drive. However, recent reports have suggested that the public API of Co-Win could be misused by the programmers to automate the process of registration of the Covid-19 vaccination and notifications.

Co-Win chief Dr RS Sharma has said that automatic booking of vaccine slots by running scripts was not possible for ineligible persons, as there are other checks such as OTP validation.

However, some experts claim that while the public API data of Co-Win alone can't be used to automate the registration process, it could be used with Robotic Process Automation (RPA) to automate the self-registration process on the Co-Win platform.
