Post-purchase CSAT for Shopify: Step-by-Step Setup Guide

Post-purchase CSAT for Shopify is a customer satisfaction survey shown immediately after a customer completes checkout.

It measures how satisfied customers are with:

The checkout flow
Payment experience
Shipping clarity
Overall purchase process

What You’ll Set Up in This Guide

By the end of this guide, you’ll have:

A CSAT project in Opin
The Web SDK enabled
An event-based trigger
A Shopify CSAT survey shown post-checkout

Step 1: Create a New CSAT Project in Opin

From your Opin dashboard, go to:

Dashboard → CX → Create

You’ll see a list of available survey types.

Step 2: Choose Customer Satisfaction (CSAT)

Select Customer Satisfaction from the list.

CSAT is the right choice for post-purchase feedback because it focuses on immediate experience, not long-term loyalty.

Step 3: Configure Your Shopify CSAT Survey

Fill in the project details.

Recommended configuration:

Project name: CSAT for Post-checkout
Survey question: How satisfied are you with our checkout experience?
Follow-up question: What could we do better?

Keep questions short and direct.
Avoid adding extra steps.

Step 4: Open Settings and Scroll to Web SDK

Once the project is created, open the Settings tab.

You’ll see options for survey links and email campaigns.
You don’t need to configure those for post-purchase CSAT.

Scroll down to the Web SDK section.

Step 5: Enable the Web SDK

In the Web SDK section, click Enable Web SDK.

This allows Opin to show surveys directly inside your Shopify store.

Step 6: Select Event-based Triggering

When asked to choose a trigger type, select Event-based.

Event-based triggering lets Shopify control exactly when the CSAT survey appears.

Step 7: Copy the Web SDK Token and Instructions

Once enabled, the Web SDK becomes active.

You’ll see:

Your SDK token
The script to add to your site
Example trigger code

Keep this page open for the Shopify setup.

Step 8: Add the Opin SDK to Shopify

In Shopify, go to:

Admin → Online Store → Themes → Edit code

Open theme.liquid and add the following inside the <head> tag:

<script src="https://cdn.getopin.com/v1/opin.js"></script> <script> OpinSDK.init({ token: "YOUR_SDK_TOKEN", debug: false }); </script>

This loads Opin across your Shopify storefront.

Step 9: Trigger the CSAT Survey After Checkout

On the Shopify order confirmation (thank-you) page, add:

<script> OpinSDK.trigger({ user: { id: "{{ customer.id }}", email: "{{ customer.email }}" }, metadata: { order_id: "{{ order.id }}", total_price: "{{ order.total_price }}" } }); </script>

Your Shopify CSAT survey will now appear immediately after checkout.
