SDK Integration

Native OTP Assist

The OTP Assist SDK provides a complete authentication flow for cards transactions. It offers to capture OTP in the merchant app without any redirection to the bank’s 3Dsecure/ACS page. This means that there's one less point of failure in the checkout process and a faster completion rate for transactions.


The Native OTP Assist SDK gives you the following key capabilities:
  • Read OTP on the merchant app without redirecting to the bank page, for eligible bins.
  • If the bin is not eligible, then it will redirect to the bank’s 3d-secure/ACS page.
