We want to have to have Aadhaar Based E-Signature API request where we as developer can send pdf with required Aadhaar e-sgn to be done by the user.

We would like to integrate an Aadhaar-based e-Signature API into our application, where as developers we can send a PDF document and allow the end user to complete Aadhaar e-sign on it.

Could you please provide guidance on the following:

1. How to use the Aadhaar e-Sign API for uploading and sending a PDF for signature

2. The complete integration steps and workflow involved

3. How the end-user authentication (Aadhaar OTP/biometric) is handled in the process

4. Steps to configure and enable this feature in a demo/sandbox account for testing

5. Any required API credentials, documentation, or prerequisites to get started

We are currently in the initial integration phase and would like to test the functionality in a demo environment before moving to production.

Kindly share the relevant documentation, API references, and onboarding steps.

Thank you.
