New Delhi: The Unique Identification Authority of India (UIDAI) has published the Aadhaar Authentication Application Programming Interface (API) specification on its website. It contains details including API data format, protocol, and security specifications.

Aadhaar Authentication is the process wherein Aadhaar number, along with other attributes, including biometrics, are submitted online to the Central Identities Data Repository for its verification on the basis of the information or data or documents available with it.

Aadhaar authentication service only responds with a “yes/no” and no personal identity information is returned as a part of the response.

Aadhaar authentication will provide a convenient mechanism for all residents to establish their identity using just the Aadhaar number and biometrics and optionally other additional demographics. It provides a national platform for identity verification and can be used to deliver services effectively to residents across the country.
