This guide explains how to set up Shopify Checkout as a merchant. When a visitor clicks a buy link, they are redirected to your Shopify store’s cart and then to Shopify’s native checkout. The overall flow matches the generic merchant setup; use this page for Shopify Checkout–specific notes.
Shopify Checkout sends customers to your Shopify cart (cart redirect). For draft-order checkout with Shop Pay one-click and bump support, see Shop Pay instead.

​
Prerequisites

  • A Shopify store with products (and variants, if you use multiple variants)
  • Admin access to your Shopify store and to ElasticFunnels

​
Step 1: Connect Shopify and enable Shopify Checkouts

  1. Go to Integrations → Operations, find Shopify, and connect your store (see Shopify Order Sync for the full flow)
  2. Enable Shopify Checkouts so postbacks are received for orders created, updated, or deleted in your store
When you enable Shopify Checkouts, a Shopify Checkouts merchant is created automatically and linked to the integration. You do not need to create the merchant manually.

​
Step 2: Assign merchant to domain

  1. Go to Settings → Domains → Edit Domain
  2. Select your Shopify Checkouts merchant (created in Step 1)
  3. Save

​
Step 3: Map products

Each product must be linked to a Shopify variant ID (a numeric ID from your Shopify store).
  1. Go to Settings → Products → Edit the product
  2. Open the Merchant information tab
  3. Find the row for your Shopify Checkouts merchant
  4. Enter the Shopify variant ID (numbers only) for this product
  5. Save

​
How to find your Shopify variant ID

  • Products with variants: In Shopify Admin go to Products → open the product → Variants → click the variant. The URL in your browser will look like .../variants/36485954240671. The number after /variants/ is the variant ID.
  • Products with a single variant: Open the product in Shopify Admin, add .json to the end of the URL, and press Enter. In the JSON, look at the variants array and use the id of the first (or only) variant.
Every Shopify product has at least one variant. Use the variant ID, not the product ID.

​
How it works

In your funnel, buy links use your product code (the same code you use for other gateways). When a visitor clicks add to cart or a buy link, we look up the Shopify variant ID you mapped for that product in Merchant information and redirect them to your Shopify store.
  • They are redirected to your Shopify store at /cart/{variantId}:1 (one unit of that variant)
  • The click ID is passed as a cart attribute so conversions can be tracked
  • From the cart they proceed to Shopify’s native checkout
Shopify Checkout does not support upsells in the same flow — it is a simple cart redirect. For upsells and one-click Shop Pay, use Shop Pay instead. Use [BUY], [UPSELL], and [DOWNSELL] tags so links auto-adapt per domain and merchant. Avoid pasting hardcoded Shopify cart URLs.

​
Postbacks

Orders from your Shopify store (including those that started from a funnel cart link) are reported via the Shopify integration. Ensure Shopify Checkouts is enabled in your Shopify integration (Integrations → Operations) so postbacks are received for orders created, updated, or deleted in the store.

​
Troubleshooting

  • “Product missing Shopify variant ID”: In the product’s Merchant information tab, enter the Shopify variant ID for the Shopify Checkout merchant. Use the steps above to find the variant ID in Shopify Admin.
  • “Shopify Checkout requires a linked Shopify integration”: Connect Shopify under Integrations → Operations and ensure the merchant or domain is linked to that integration so the store domain is available.
  • Wrong gateway on checkout: Verify the domain is assigned to your Shopify Checkout merchant.
  • Link not working: Confirm the product has the correct Shopify variant ID in Merchant information for this merchant.
