Why Does My Shopify Product Copy Workflow Stop After 3 Products?

Hi,
I am automating the copying of products from one Shopify store to another using an n8n workflow. Although the source store has 6 products, the workflow only copies 3 products to the destination store. I am trying to understand why the loop stops at 3 products and why the loop displays a done branch even though not all products have been copied.
Below is a snippet of my current workflow configuration:
JSON{ “meta”: { “instanceId”: “63bedc4dfa8618b205589ef9c8a003968ec01fb80782197e45c6ba51a0a50da2” }, “nodes”: [ { “parameters”: { “url”:

When you see that only 3 products are being copied—and that the loop shows a done branch even though there are 6 products—it’s usually because the loop condition that checks for a “next” link (or additional batch) isn’t being met after the third iteration. Here are some key points to consider:
-
Pagination Settings:
The workflow’s HTTP Request node for getting a product is configured with a limit of 1 (see parameter: “limit”: “1”). This means you are requesting one product per API call. If the Shopify API’s response header (usually in the “link” field) does not indicate that there is a subsequent page after the third product, then your “does product link have next?” check will return false. In this case, the loop finishes—even though the count node indicated 6 products, the pagination wasn’t properly followed. -
Loop Over Items Node Behavior:
The Loop Over Items (splitInBatches) node automatically terminates when all the items in the batch have been processed. If your subsequent nodes depend on a “next” link in the headers to continue the loop and that link is absent after 3 iterations, the workflow will branch into the done branch. -
Suggestions for Resolution:
- Review Pagination: Verify how the Shopify API paginates its results. In many cases, Shopify sends a “Link” header with URLs for the next (or previous) page. Ensure that your code node and the subsequent “if” node are correctly extracting and testing the presence of a “next” link.
- Adjust Request Parameters: If you intend to process all 6 products, you might consider increasing the limit on the product-getting node or properly utilizing the next link provided by Shopify.
- Debug the “if” Node: Confirm that your condition checking if the product link contains “next” is robust (for example, that it isn’t affected by extra spaces or unexpected formatting).
- Batch Size and Loop Configuration: Make sure the Loop Over Items node’s configuration (such as the batch size) aligns with your desired iteration over all available products.
By revisiting the pagination mechanism (how the “next” link is generated and used) you should be able to ensure that all 6 products are processed rather than stopping at 3.
