API problem - Google Merchant Center broken links

Topic summary

Product links in Google Merchant Center are mismatched after syncing from Shopify via API, with multiple items pointing to the wrong product pages (e.g., a sweatshirt linking to a tote bag). The merchant suspects the Shopify API as the cause and seeks help to correct links.

Proposed diagnostics focus within Google Merchant Center (GMC):

  • In Data sources, review the feed’s attribute rules to see if any are rewriting website URLs (the link attribute).
  • On affected product pages, check Additional details to identify modifications coming from a supplemental feed or other feeds, and confirm no manual changes were made.

No fix has been confirmed yet. The thread remains open pending the results of these GMC checks and identification of whether feed rules or supplements are altering URLs.

Hi, everyone!

We are having some problems with our Google Merchant Center products. They are connected through our Shopify API, but the links they are connecting our products to are all wrong. For example, we have a Sweatshirt Essential Stoned Blue that is linked to a Tote Bag we have. This has happened to several products of ours.

As we believe this is related to our Shopify API, is there anyone who can help us get our products with the right links?

That is very unusual. Let’s check some details.

Go to Google Merchant Center > cog icon > data sources > click on your feed > check if you have any attribute rules enabled that is changing the website URLs

Then check products > click on a product with the issue > scroll to the bottom and view the additional details > now view if there are any modifications done using a supplement feed or other feeds.

Also check it was not changed manually.
