How to use Catalog Matching for Amazon

Learn how to use Catalog Matching in your Amazon channel to match products to existing ASINs, review results, and handle unmatched items.

In this guide, we explain how to use the Catalog Matching feature in your Amazon channel to match your items to ASINs on Amazon.

Important: If enabling this feature on an existing channel (API), make sure to remove all categories before starting.

---

Before you start

You’ll need

• An Amazon channel in Channable
• No items categorized in the Categories step (if using Catalog Matching in an existing Amazon channel)

Good to know

• You don’t need to activate your channel or link a seller account to use the catalog matching feature, however, this can improve the amount of matched items. You will also need to link it to receive information back from Amazon and publish your listings.
• If you're missing required fields in the first step, you can fill them in by creating a new master rule group and adding rules to it.

1

Enable catalog matching

1. Go to the Settings step in [your Amazon channel].
2. Set the Listing requirement level to Add offers to existing Amazon listings.
3. At Catalog item matching, click the toggle to enable it. Additional fields will appear.
4. Fill in the required fields:

   • External ID number: Select the field that contains your product identifiers (e.g. EAN, GTIN, or UPC numbers).
   • External ID type: Select the field containing the product identifier types you’re using (e.g. EAN, GTIN, or UPC)

Important: make sure the External ID types use lowercase letters (like gtin instead of GTIN)

Note: If you don’t have a field containing your ID types, add a new one and fill it using a master rule.

Example Master rule

1. In the sidebar, go to Master rules.
2. Create a new rule group and give it a descriptive name (like 'Amazon catalog matching').
3. Click Continue. You will be directed to a Rules page.
4. Click Create rule.
5. Give your rule a descriptive name (e.g. 'Categorization - PRODUCT')
6. Click Create.
7. Create a rule to sort your items:

----

Example rule: assign EANs

1. If id length exceeds "[FILL LENGTH HERE]"
2. Hover over the If part and click + > And.
3. For And, fill in id length doesn't exceed "FILL LENGTH HERE" .
4. For Then, map [field containing ID type information] and set to value "ean".

----

1. Click Save rule.
2. Repeat and create new rules for any remaining ID types.

• ASIN project field: Choose a project field to store ASIN information in.

  • If field is empty: Channable will fetch ASINs from Amazon and fill the field with those values.
  • If field contains values: Your ASINs will be used first, and we’ll fill in the rest.

Note: If you don’t have an empty project field to use to store your ASINs, you can add a new one.

1. Use Exclude unmatched items to control which items are sent to Amazon.

   1. Toggle on: Only items with an ASIN are included.
   2. Toggle off: All items are included.
   3. You can review matched and unmatched items in Catalog matching either way.
2. Click Save.

Review matches

In the Catalog matching step, you'll see an overview of which of your item IDs we could match to ASINs.

How to review:

1. Items are separated into three possible groups:

   1. Matched: A 1:1 match found on Amazon.
   2. Multiple matches: Several possible matches found.
   3. No match: These items don't exist in Amazon catalog.

Note: We cover how to exclude items without matches from your channel setup in Step 7.

1. In the Amazon product title column, click on the links to view the matched Amazon listing page.
2. In the Source column, you can see whether the match was set using our system (Channable) or from values you provided in the ASIN project field you selected in the previous step (User)

Review and adjust categories

You can skip this step if your items are all already placed in the PRODUCT category.

If your items have different categories, you'll need to remove any pre-categorized items and create a master rule to ensure all items fall under the same PRODUCT category.

Example master rule

1. Go to Master rules step. In the rule group you created in Step 1, click Rule > Create rule.
2. Give your rule a descriptive name (e.g. 'Categorization - PRODUCT')
3. Click Create.
4. Leave the condition (IF) as If all
5. For the action (Then), click the dropdown after 'take' and select Internal fields > Category.
6. after 'and', select set to value . In the text box that appears, write 'PRODUCT' in all caps.
7. Click Save rule.

Map shared attributes

1. Go to the Build step and click the Shared attributes tab.
2. Map any remaining fields marked Required by marketplace.

These remaining fields should be related to:

• Price
• Condition (e.g. new, used)
• Compliance
• Stock
• Shipping promise

1. Check and map any remaining fields mapped as Recommended to see if they apply to your setup.
2. Click Save.

5

Map category attributes

1. Go to the Attributes per category tab in the Build step. You should see one category: PRODUCT.
2. Click on PRODUCT.
3. Review all fields and map attributes relevant to your items to a value or project field.
4. Click Save.

Test your setup

Testing your channel setup helps you check your channel setup and listings with Amazon before you publish them.

To test your setup, click Test channel setup.

You can review your feedback in the Feedback tab in the Results step.

I see 8541 OR 13013 errors

Check the whether your channel meets the right conditions:

• You only have one category - PRODUCT . You can check this in the Attributes per category tab in the Build step.
• The Quantity attribute has a relevant field or value mapped to it.
• The Condition attribute has a relevant field or value mapped to it.

If your channel meets the above conditions persist after 48 hours, there may be listing restrictions on the ASIN. If you aren't sure, contact our Support team.

Tip: You can test your setup as many times as needed.

Handle unmatched items

Use this workflow when you manage a brand catalog with unknown Amazon coverage and need separate channels for existing and new listings.

Enable Exclude unmatched items in your Offer-only channel. This sends only items matched to Amazon listings, and simplifies your setup.

The Catalog matching step shows matched and unmatched items whether Exclude unmatched items is enabled or disabled. Download the No match results to create a separate channel for unmatched items.
