e-KYC OTP Request

📘

The OTP is sent from the bank itself.

❗️

You need to encrypt the value of the aadhar number as well.

Aadhaar Encryption -

1. Decode public key using base64 encoding technique. (public key for UAT and production are different)
2. Compute RSA encrypted signature using decoded key and message.
3. Encode encrypted signature with base64 encoding to send message on API.

Public Key for Aadhaar Encryption - (UAT)

EKYC Steps -

1. It is mandatory to use e-KYC OTP request, e-KYC OTP Verification and Biometric before AePS transaction.
   Please make sure you use these APIs consecutively.
2. The whole process of e-KYC is to be done for every merchant just once.
3. For both of these services, Daily authentication i.e. 2FA is mandatory and to be done everyday.
