Note :
If action is ACTION-REQUIRED then initiate the Merchant Biometric KYC.
If action is NO-ACTION-REQUIRED then Merchant biometric kyc is successfully done.
If outletAadhaarNumber contains the last 4 digits of the Aadhaar, then in the Merchant Biometric KYC, encryptedAadhaar is optional.
However, if outletAadhaarNumber is empty, then encryptedAadhaar becomes mandatory and should contain the merchant’s Aadhaar number.

📘
Note :
If the status is PENDING or APPROVAL_PENDING, it indicates that the approval is still pending at the bank’s end. To fetch the latest status, call the Biometric Status API at 30-minute intervals.
If the status is APPROVED, it means the outlet has been approved by the bank and is now eligible to initiate transactions.
