Installing Customei takes less than two minutes. This page walks through the install flow and what to check right after.

​
Before you begin

  • A Shopify store you’re the owner or admin of.
  • A browser you’re already signed into Shopify with.
You do not need a Shopify Plus plan — Customei works on every Shopify plan.

​
1. Install from the Shopify App Store

1

Open the app listing

Go to the Customei listing on the Shopify App Store and click Add app.
2

Pick the store to install on

If you manage more than one store, Shopify will ask which one. Pick the store you want to personalize.
3

Grant permissions

Shopify will show the permissions Customei needs — things like reading products, writing to orders, and creating a hidden “fee product”. Review and click Install.
4

Pick a plan

You’ll land on Customei’s plan picker. Pick a plan (the free trial is fine to start) and approve the charge in Shopify’s checkout.
After the charge is approved, Shopify drops you into the Customei admin inside your store’s embedded app frame.

​
2. Finish the setup checklist

The Dashboard shows a setup checklist the first time you open Customei. Going through it is the fastest way to get a working storefront:
  1. Create your first design template → walkthrough.
  2. Build your first option set → walkthrough.
  3. Link them to a Shopify product — from Products, pick the product you want to personalize.
  4. Enable the storefront widget → walkthrough.
Each step links back into the relevant guide. You can leave and resume at any time.

​
3. Verify the install

Two quick checks to make sure Customei is wired up correctly:
  • Open any product page on your storefront. Customei’s auto-loader runs on every product page. Even before you’ve personalized anything, the runtime should be loaded — you can confirm in your browser’s DevTools by looking for a customei-options.js request on the Network tab.
  • Visit Settings → Apps and sales channels in Shopify admin. Customei should be listed and show its status as Active.
If either check fails, see Troubleshooting.

​
What Customei creates during install

Customei sets up a few things behind the scenes so you don’t have to:
  • An account that owns all of your templates and option sets. Invite teammates from Account → Members.
  • A hidden fee product (if you’re on a non-Plus plan) used to apply price add-ons in the cart. Don’t delete this product. See Fee Variant strategy.
  • A webhook subscription for orders and app lifecycle events, so Customei can generate print files when orders are paid.
