1. How do I generate an OTP for call verification?

Not directly, but we can do the following:

  1. $system.time provides value like: 18:40:44.165

  2. We can use the “Regex Extract” to extract the last 3 digits (milliseconds) using Regex .([0-9]{3}) and the last digit of seconds ([0-9])\., that is 4.165 and save it in $flow.key.otp_1 and otp_2

  3. Concatenate both to create a 4 digit OTP.

How to do it:

  1. Operation Widget Overview

2. Input

3. $flow.key.otp_1
