Overview

Before your Post-Purchase Upsell offer can show in the checkout flow, it needs to be enabled in two places:

  1. In your Nosto admin – where you manage the campaign

  2. In your Shopify admin – where you activate the extension in your Checkout settings

If either side is missing or misconfigured, the upsell page won’t appear.

Step 1 – Enable a Campaign in Nosto

We’ve made it easy to get started by creating one campaign for you out of the box. Here’s what’s pre-configured for you:

  • Show up to 4 products

  • Personalized Algorithm, selecting products your customer is likely to buy

  • 10% discount (applies to all products shown)

  • Fallback: If no personalized products are available, the campaign shows Best Sellers ➝ ’Most Viewed in last 7 days’

You can use this as-is, modify it, or create your own from scratch.

To review or create a campaign:

  1. Go to Nosto Admin -> Product Experience Cloud -> Post-Purchase Upsell

  2. Open the default campaign or click Create Campaign in the upper left corner

  3. Set your preferences:

    • Audience and Discount logic

    • Algorithm type

    • Filters or Merchandising rules

    • Fallback

  4. Save and enable the campaign.

Once enabled, the campaign is active – but it still won’t show until you connect it on the Shopify side.

Don’t forget to review your timer duration and message under

Nosto Admin → Product Experience Cloud → Post-Purchase Upsell → Settings.

Default is 60 seconds.

Step 2 – Activate Nosto in Shopify Admin

Shopify needs to know which app should provide the post-purchase page. Here’s how to connect Nosto:

  1. Go to your Shopify Admin

  2. Navigate to Settings → Checkout

  3. Scroll to Post-purchase page

  4. Select Nosto from the list

  5. Click Save at the bottom of the page

That’s it. Your upsell is now active for eligible checkouts.

Notes

  • If no campaign is enabled in Nosto, or if the app isn’t selected in Shopify, the offer simply won’t show – the checkout process continues without interruption.

  • You can disable the extension at any time from the Shopify Checkout settings, or by disabling the campaign in Nosto.
