Amazon shows your products in search and filters using its own set of accepted values. For example, Shopify might say Slate, but Amazon’s catalogue expects Beige from a fixed colour list. If the two don’t match, your product can still go live — but shoppers may not see it when they filter or search by that value. Value Mapping lets you tell the app which Shopify value should be sent as which Amazon value, one time, for an entire template.

When do you need Value Mapping?

You don’t need it for every product. The app checks Amazon’s recommended value list for each attribute in your template, and if it finds a mismatch with the values in your Shopify catalogue, it shows a blue banner at the top of the Templates page:

Value Mapping is recommended for some templates. We have found some Amazon recommended values for your chosen attributes. Map these attribute values to have greater product visibility on Amazon.

When you see this banner, it means at least one of your templates has attributes (such as Colour, Size, Material, etc.) whose Shopify values don’t exactly match Amazon’s accepted values. Mapping them is recommended — not mandatory — but doing it improves how Amazon displays, sorts, and filters your products.

Where to find the option

Open the app and go to Settings → Templates. Under each template card, you’ll see a Map attribute values link in blue. The link appears for every template that has at least one attribute Amazon has a recommendation for.

Steps to map your values

1. On the Templates page, find the template you want to update and click Map attribute values.
2. The Value Mapping screen opens. At the top you’ll see the template name, the assigned Amazon category, and how many products are in this template.
3. Below that, every attribute that has recommended values is listed. Click the attribute (for example, Color Map) to open the mapping window.
4. The Map Shopify values with Amazon window appears. The left column shows your Shopify value (e.g. Slate); the right column has a dropdown of all the values Amazon will accept for that attribute in the chosen category.
5. Pick the matching Amazon value from the dropdown. If you have several Shopify values, use the pagination at the bottom of the window to step through them one by one.
6. Click Save to apply the mapping for this template.

Why this matters

Amazon’s search and category filters depend on standardised values. If a shopper filters by Beige 3D printers, Amazon only shows products whose Color Map attribute is exactly Beige — not Slate, Sandy Brown, or any other Shopify-side label. Mapping ensures your listings are part of that search result and not hidden away.
