## What the Initiate Esign Flow API does

Initiate Esign Flow begins electronic signing. You submit the documents and the recipients who must sign, and the flow is created and sent for signature.

Aadhaar-based eSign carries the same legal standing as a handwritten signature under the Information Technology Act. That is what allows loan agreements and mandates to be executed entirely remotely.

1.  Executing loan agreements without paper
    
2.  Collecting signed mandates during onboarding
    
3.  Remote signing of insurance proposals
