Random Alphanumeric Coupon Code Generator

I want to generate alphanumeric coupons for my woo commerece store, including special characters.

is there a way to do it, using the functions and tools available in make.com

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?


Interesting question, I generated a 6-character string for your cupon by doing the following:

1-. create an array from a string delimited by . like this using the split fucntion : {{split(“A.B.C.D.E.F.G.H.I.J.K.L.M.N.O.P.Q.R.S.T.U.V.W.X.Y.Z.!.@.#.$.%.^.&.*.”“”; “.”)}}

2-. And then create six variables, getting a random number for the position of the array
3- Finally put all array values in a single variable.

This will consume only 3 operations and you can store the resulting Cupon on a DB to avoid duplicates.


Hi @Rafael_Sanchez,

That is a really good approach! :+1:

While answering this, I built a scenario using Repeater and Aggregator, and it used 18 Operations to generate a 16-character code. Your solution is much, much better than that. :+1:


Generate your coupon code in a single step :+1:


  • I used ABCDEFGHJKMNPQRSTUVWXYZ23456789!@#$%^& repeated 4 times to allow for repeated characters in the code, and to make it way less likely that a duplicate is generated. You can have more times but there are diminishing returns

  • I removed ambiguous characters 1ILO0

  • I used a triple shuffle - you could add more shuffles to randomise the array more but there are diminishing returns

  • I used substring 0;6, but you can change the 6 to however long you want your output to be
