This guide walks you through installing Kleep on your Shopify store. Kleep offers four solutions on Shopify: AI Sizing, Search, Similar Products and AI Try-On.

​
Integration Process Overview

Here’s what to expect from contract signing through go-live and beyond. The end-to-end integration typically takes around 5–6 weeks.

​
Onboarding

1

Contract signed & billing set up

Once the contract is signed, your Kleep representative kicks off billing via GoCardless: Set up direct debit →.
2

Onboarding kickoff meeting

A short call with your Kleep representative to align on timeline, technical contacts, and any store-specific requirements before installation begins.
3

Fill out the onboarding form

After the kickoff, we’ll ask you to share a few details about your company, billing, store environments, and returns setup so we can prepare the integration.Fill out our onboarding form →It takes about 5 minutes. Once submitted, our team will review your responses and confirm the next steps within 1 business day.
4

Share your Shopify URL & collaborator code

Send us your store address (e.g. your-store.myshopify.com) along with your collaborator request code so we can request access to your store.
Environments — If you have several Shopify instances (e.g. different regions or brands), please send us a collaborator code for each shop — we need one code per store.If you have multiple Shopify environments (dev, staging, production), you need to configure Kleep for each one:
  • Production store — Main store, fully configured
  • Staging/Dev stores — For testing before pushing to production
For each environment:
  1. Install the Kleep app
  2. Enable the App Embed
  3. Contact your Kleep CSM to link the environment to your account
Not sure where to find these? In your Shopify admin, go to Settings → Users and permissions — your myshopify.com URL is shown at the top, and the Collaborator request code is listed under the Collaborators section. See Shopify’s help article on collaborator accounts for more detail.
5

Accept our collaborator request

We’ll send a collaborator access request from our Shopify Partner account. Approve it from Settings → Users and permissions → Collaborators in your Shopify admin.
6

Install the Kleep app on each shop

Once we have collaborator access, we’ll send you an app installation link for each store. You’ll need to install the Kleep app separately on every Shopify store where you want Kleep enabled.
7

Choose the AI Sizing button placement

Review our suggested positions for the “Find my size” button and pick the one that fits your storefront: AI Sizing button positioning Figma →.

​
Installation & testing

1

We install Kleep on a duplicate theme

Our team duplicates your current Shopify theme and installs Kleep on the duplicate, so your live storefront stays untouched while you test.
2

Preview & feedback

We send you a private preview link to test the integration end-to-end and share any feedback or adjustments needed.
3

Go live

Once you sign off, the Kleep team runs a final QA validation (display, data quality, tracking, performance) and we publish Kleep on your live theme.

​
Post-integration

1

Client dashboard access

We provision credentials for your team to access the Kleep Dashboard, where you can monitor Kleep performance KPIs in real time.
2

Fit Feedback enabled

We enable Fit Feedback in your dashboard so your team can refine Kleep’s size recommendations using real-world fitting data.

​
Returns integration (optional)

If you use a returns management platform, Kleep can integrate return data to improve size recommendations. Supported Returns Providers
  • Global-e
  • Aftership
  • Fast Return
  • Return Go
  • Other (contact us)
Configuration
  1. In the Kleep Dashboard, go to Settings → Returns
  2. Select your returns provider
  3. Follow the provider-specific instructions to connect your account
If your provider is not listed, contact us at support@kleep.ai — we can set up a custom integration via SFTP or API.

​
Installation methods

Kleep’s storefront solutions (the AI Sizing button, Similar Products, AI Try-On) can be integrated in two ways: Each solution page below covers both paths: the standard installation and, when relevant, a Manual installation section.
If you don’t see Kleep blocks in the “Apps” tab when clicking “Add block” in the theme editor, your theme is likely a vintage theme — use the manual installation path described in each solution page.

​
