Similar apis for demographic auth

What is the difference between these set of APIs used in demographic auth flow ?

authMethod as “DEMOGRAPHICS” :
https://healthidsbx.abdm.gov.in/api/v1/auth/init
https://healthidsbx.abdm.gov.in/api/v1/auth/confirmWithDemographics

authMode as "DEMOGRAPHICS"
https://dev.abdm.gov.in/gateway/v0.5/users/auth/init
https://dev.ndhm.gov.in/gateway/v0.5/users/auth/confirm

Why there are two different set of APIs for same use-case i.e. demographic authentication ?
As a hospital, Which one to use when ?
