I’m currently working on a case type for an E-Seva Aadhaar Update application in Pega Platform. As part of the user verification process, I want to send an OTP to the Aadhaar registered mobile number of the citizen before allowing them to proceed with the update.

My current setup:

• Case Type: AadhaarUpdate

• Stage: Verification

• I’ve captured the Aadhaar Number from the user

• I want to trigger an OTP to the mobile number linked with Aadhaar (ideally from UIDAI or a secure API)

What I Need Help With:

1. Is there a standard or recommended approach in Pega to send an OTP to the Aadhaar-linked mobile number?

2. Does Pega provide any built-in integration or connector to UIDAI or similar government services?

3. If an external API (e.g., UIDAI’s OTP service) is needed, how should I configure the connector rule (REST integration) and handle the authentication?

4. How can I store the OTP temporarily and validate it against the user input in the next step?

5. Any best practices for managing security (masking, expiration, retry limits)?
