Then ID API is the way to go! https://docs.smileidentity.com/products/core-libraries/restful-integration/id-verification ID API is a REST API that lets you verify an ID number as well as query personal information associated with that ID number via an HTTP Request. It can perform basic KYC Services, including verifying if the ID number that you provide exists, as well as retrieving a user's personal information from the regulatory database.
Then your answer is Web API : https://docs.smileidentity.com/products/web-api Easily integrate our Web API libraries on your server to verify an ID number; query personal information associated with that ID number and perform facial recognition on selfies that have been uploaded, and finally validate a user’s identity against the relevant ID Issuing Authorities.
