Can you pay AI agents to promote your products? What Shopify’s new commission means

What happened

In a Shopify developer changelog post, Shopify said merchants running Shop Campaigns with external platforms turned on now include its Catalog API as one of those platforms. Their campaign budget becomes a commission for AI agent developers who send buyers to the product. For those products, the links the agent receives point to shop.com rather than the store’s own website. Shopify’s promoted placements guide asks developers to label promoted results and say they may earn a commission before a buyer acts.

What this means for your store

1. Check your Shop Campaigns settings: if you run Shop Campaigns in the US with external platforms on, your products may already be offered to AI agents as paid placements, and those sales finish in Shop, not on your site.
2. Watch your attribution: catalog traffic arrives with utm_source=shopify and utm_medium=catalog, so you can see it separately in your analytics.
3. Don’t treat it as a shortcut to AI visibility: Shopify’s docs don’t say a higher commission moves a product up the list, and most AI assistants don’t use this program. Clear product data still decides what agents can find and compare. Our post on Shopify’s catalog opening to brands outside Shopify explains how the catalog works.

The technical details

Developers opt in per saved catalog and pass its catalog_id on search_catalog calls. Promoted variants include a placement object of type affiliate with commission.percentage.value; organic results don’t. Attribution needs the buyer to follow the variant url or checkout_url exactly as returned. Adding a variant through Cart MCP or Checkout MCP doesn’t carry attribution yet.
