Hi @Shashwat_Chopra,

A simple way to generate coupon codes would be to convert unique id to Base 64. Like this:

This example above will give you 16-character code including uppercase (A-Z), lowercase (a-z) and numbers (0-9), but **not all special characters** , only “+” and “/” symbols. Like this:

It would be possible to get exactly what you want including special characters using a Repeater module (from Flow Control) and either Set Variables or Switch modules… but this would use a lot of operations. Is that something you’d like to try?
