How to setup Stripe codes for your AppSumo deal

August 22, 2022

I recently published an AppSumo deal for Beanvest and try to find a way to quickly create 10,000 coupon codes on Stripe.

As I did not find any solution to do so, here's a script I created to quickly create those 10,000 coupons with 100% off forever (actually it creates only 1 coupon but with 10,000 codes to make it more readable on your Stripe account).

This script also generates a csv file with all coupon codes which is ready-to-upload on AppSumo.

You can copy-paste the script below, or simply do:

git clone

The script is also available on Github

Script to generate Stripe coupon codes for AppSumo

'use strict'
// Copy-paste a Secret key from
const STRIPE_API_KEY = 'sk_live_.........'
// Coupon code length (including prefix). Must be between 3 and 200
const CODE_LENGTH = 40
// Number of coupons to generate. Must be between 100 and 10000
const NB_COUPONS = 10000
// Optional prefix for codes
const PREFIX = 'SuMo'
// List of characters to generate code from
const chars = 'AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz1234567890'
// This csv file will contain all your AppSumo coupon codes
const fileName = `AppSumo-${NB_COUPONS}-codes.csv`
const fs = require('fs')
const stripe = require('stripe')(STRIPE_API_KEY)
async function createCodes() {
  const stream = fs.createWriteStream(fileName)
  const coupon = await{
    name: 'AppSumo Lifetime Deal',
    percent_off: 100,
    duration: 'forever'
  for (let i = 0; i < NB_COUPONS; i++) {
    const code = await createPromo(
    console.log(`${i + 1}/${NB_COUPONS} - ${code}`)
  console.log(`✨✨✨ ${NB_COUPONS} coupons created on Stripe & saved in a csv file ${fileName}`)
function generateRandomCode () {
  return PREFIX + Array.from(
    { length: CODE_LENGTH - PREFIX.length },
    (v, k) => chars[Math.floor(Math.random() * chars.length)]
async function createPromo (coupon) {
  const code = generateRandomCode()
  try {
    await stripe.promotionCodes.create({
      max_redemptions: 1
 } catch (e) {
  return code

Hope you found this useful for your AppSumo LTD :)
