How to add a referral program to your Shopify Thank you page

Invite customers to share while their purchase is still fresh, without interrupting checkout or sending them into a separate affiliate portal.

Why ask for a referral after the purchase?

A referral request is strongest when it follows a real customer action.

Immediately after checkout, the customer has just chosen the product, completed payment, and confirmed their relationship with the store. The product is still top of mind, and the invitation does not compete with the original purchase decision.

That makes the Thank you page a natural place to say:

Know someone who would love this?
Share your personal referral link and earn progress toward your reward when an eligible friend orders.

The customer is not being asked to become an affiliate or launch a campaign. They are being given a simple way to share a product they have just purchased.

The post-purchase advantage

Ask after the customer has chosen the product—not while they are still deciding whether to buy it.

Choose the surface

Thank you page or Order status page?

The two pages are related, but they serve different moments in the customer journey.

Immediate moment

Thank you page

The Thank you page appears immediately after the customer completes checkout. It is the strongest placement for capturing fresh purchase enthusiasm.

  • Shown directly after checkout
  • Seen only once
  • Best for an immediate sharing invitation
  • Strongest when the message is brief
Return visits

Order status page

Customers can return to the Order status page later to check order details and shipping updates.

  • Available after the original checkout
  • Can be visited multiple times
  • Keeps the referral link available later
  • Useful when customers are not ready to share immediately

Should the referral widget appear on both?

For many stores, yes.

The Thank you page captures the immediate moment. The Order status page gives the customer another opportunity to find the link when they return to review the order.

The same compatible referral widget may be added to either page or to both. The merchant’s actual choices in Shopify’s checkout and accounts editor determine where it appears.

Installation

How to add a referral block to the Shopify Thank you page

Installing a referral app does not necessarily place its widget on the page automatically. The merchant adds compatible app blocks through Shopify’s checkout and accounts editor.

1

Install a compatible referral app

Choose a Shopify referral app that provides a Thank you page or Order status page checkout UI extension.

2

Open Shopify’s checkout settings

From Shopify admin, go to Settings, then Checkout.

3

Edit the checkout configuration

In the Configurations section, open the configuration you want to customize.

4

Select the Thank you page

Use the page selector in the checkout and accounts editor to open the Thank you page.

5

Add the referral app block

Open the Sections or Apps sidebar, find the referral block, add it to the page, and place it in the supported area you prefer.

6

Save and preview the configuration

Review the desktop and mobile previews, then save the checkout configuration.

Adding the Order status block

Repeat the page-selection and block-addition steps for the Order status page.

Adding a widget to the Thank you page does not mean it has automatically been added to the Order status page. Treat the two placements as separate merchant choices.

Where should the referral block appear?

The order confirmation and essential customer information should remain clear. The referral invitation should support the post-purchase experience rather than make the page feel like a second sales funnel.

A practical placement is after the customer has seen:

  • Confirmation that checkout succeeded
  • The order or confirmation number
  • Important contact or delivery information

The referral prompt can then become the next optional action.

FirstOrder confirmation

Reassure the customer that the purchase succeeded.

ThenEssential order information

Show the details the customer expects to see.

Next optional actionReferral invitation

Make sharing visible without competing with confirmation.

Stores using several post-purchase apps should also consider how those calls to action compete with one another.

Referral copy

What should the post-purchase referral message say?

The message should answer three questions quickly:

  1. Why should the customer share?
  2. What can the customer earn?
  3. What must happen for the referral to qualify?
Share and earn

Know someone who would love this?

Share your personal referral link. When an eligible friend places a qualifying order, you will earn one referral point toward your reward.

RewardEarn three referral points and receive one free product.

Keep the language concrete

Prefer:

Earn three referral points and receive a $20 voucher.

Avoid:

Ordinary customers should feel that they are sharing a link—not enrolling in a professional marketing program.

Sharing options

Which referral channels should you include?

The best channel is the one the customer will actually use. Familiar choices reduce friction.

Copy link

The universal option. Customers can paste the link wherever they prefer.

Email

Useful when the recommendation needs more context or is sent to a specific person.

Text message

Natural for direct, personal recommendations between people who already know one another.

WhatsApp

Important for stores whose customers rely on WhatsApp for personal and group communication.

Facebook

Useful for customers who share product discoveries through their social networks.

More buttons are not always better. Choose the channels that fit the store’s customers and keep the widget easy to scan on mobile.

Referral flow

What happens after the customer shares?

1

The customer shares a personal referral link

The link identifies the referring customer without requiring the customer to manage a campaign.

2

A friend visits the store

The referral can be carried through the friend’s shopping journey and connected to an eventual order.

3

The friend places an order

The app evaluates whether the order satisfies the merchant’s referral rules.

4

A qualifying referral earns a point

Ordinary qualifying referrals can be recorded automatically. Unusually rapid activity may trigger merchant review.

5

The customer reaches the reward threshold

The merchant can approve the reward manually or configure automatic reward approval.

A referral link is only the beginning. The program also needs qualification rules, reward tracking, customer communication, and a clear process for issuing the earned reward.

Common Thank you-page referral mistakes

Assuming installation automatically adds the widget

The merchant still needs to add the app block to the desired page in Shopify’s checkout and accounts editor.

Hiding the reward behind vague language

State what customers earn and how many qualifying referrals are required.

Overloading the page with sharing choices

Include useful channels, but keep the widget compact and easy to use on a phone.

Competing with the order confirmation

The customer should never wonder whether the original order succeeded.

Showing a link without explaining qualification

Customers should understand that the friend’s order must satisfy the store’s referral rules.

Treating customers like affiliates

Avoid partner terminology, campaign dashboards, and commission language when the goal is customer word of mouth.

Frequently asked questions

Shopify Thank you-page referral programs

Can I add a referral program to the Shopify Thank you page?

Yes. A compatible Shopify app can provide a checkout UI extension that the merchant adds to the Thank you page through Shopify’s checkout and accounts editor.

What is the difference between the Thank you page and the Order status page?

The Thank you page is shown immediately after checkout and displays only once. Customers can return to the Order status page later to review their order and shipping updates.

Should a referral widget appear on the Thank you page, the Order status page, or both?

The Thank you page captures immediate post-purchase enthusiasm. The Order status page gives customers another chance to find the referral link later. Merchants may choose either page or add the same compatible widget to both.

What should a post-purchase referral message say?

The message should briefly explain the reward, state what qualifies, and make sharing easy. It should not require the customer to interpret complicated point rules or affiliate terminology.

Which referral sharing options should I offer?

Common choices include copy link, email, text message, WhatsApp, and Facebook. Merchants should prioritize the channels their customers are most likely to use.

Does adding the Kudovia app automatically add its referral widget to Shopify?

No. After installing Kudovia, the merchant adds the Kudovia block to the Thank you page, Order status page, or both through Shopify’s checkout and accounts editor.

Make the post-purchase moment useful

Give customers an easy way to share while the purchase is still fresh.

Keep the invitation clear, put the reward in plain language, and let Shopify merchants decide whether the widget belongs on the Thank you page, the Order status page, or both.
