Add offers to products already selling on Amazon

This article explains how to set up your Amazon channel in Channable to add offers to items already in Amazon’s catalog.

Caution: This guide is dependent on all your items already existing in Amazon’s catalog. If you’re not sure whether all your items are in Amazon’s catalog, visit our troubleshooting guide.

---

Before you start

You’ll need

• ASINs of your items

• An Amazon account

Good to know

• If an item is part of a brand enrolled in Amazon Brand Registry, you need to be a Brand Representative or Authorized reseller list it

• Items from certain categories require approval from Amazon to list.

1

Create your Amazon channel

1. In Channable, go to Projects > [Your project] > Channels.

2. Click + Create Channel and select Amazon.

3. Fill in your channel settings:

   1. Name: Choose a name for your channel. This is for your reference only.

   2. Unique ID per item: Select the field containing your product IDs (often id).

   3. Amazon Country: Select the country (Amazon Marketplace) you want to advertise your listings in.

   4. Listing requirement level: Select Offer only.

   5. Amazon error language: Select your preferred error language.

   6. Use master rule group (optional): Add a master rule group or leave this empty.

4. Click Continue.

2

Categorize your products using rules

For your setup, you can skip the Categorization step and instead categorize using rules.

1. Go to the Rules step.

2. Click Create rule.

3. Create the following rule:

If [FIELD CONTAINING ASINS] isn’t empty

Then take category and set to value "PRODUCT".

1. Click Save.

3

Create rules to enrich, filter, and refine your product data

When product data is incomplete or doesn’t match Amazon’s required format, use rules in Channable to transform and optimize your data. See Create rules for more information.

4

Map shared attributes

1. In [your Amazon channel], go to the Build step and click the Shared attributes tab.

2. For Merchant Suggested ASIN, select the field containing your product ASIN.

3. For External product ID, click + Add and map:

   1. Type: Click the dropdown > Static value and select the ID format used (e.g. ean, gtin, upc) This value is case sensitive and must be lowercase (ean, gtin, upc).

   2. ID: Map the corresponding field in your import containing your product ID.

Important: You must fill both External Product ID and ASIN. This improves the chance of your products being listed on Amazon.

Note: If your import field uses uppercase (EAN/GTIN/UPC), create a rule to convert it to lowercase.

Example rule:

If all

Then take id_type and modify text lowercase all words

1. For Purchasable offers (Standard and Business price):

   • For Standard: map attributes under Purchasable offer (Standard) for Offer information and Discount price as needed.

   • For Business price: Map attributes under Purchasable offer (Business price) and use + Discount to add discount details if needed.

   • If you don’t want to send pricing information, ignore this section.

Note

• The Repricer only reprices the Standard offer.

• You need to be enrolled in the Amazon Business program to set Business price

1. Click Save.

Map category attributes

Category attributes are specific fields attributed to items belonging to certain categories.

If you skipped the Categorization step as outlined in Step 2, you should only see the PRODUCT category.

Important disclaimer

Amazon updates its listing requirements often, and there are thousands of product categories. This means we can't tell you exactly which attributes you need to map to successfully list your products.

We recommend mapping at least the following attributes:

• Quantity (in Fulfilment Availability section)

• Item Condition

• Country of Origin

• Fulfilment availability

To find out what information Amazon requires for your specific products, download Amazon's inventory template.

For specific instructions, select your fulfillment use case (MFN / AFN/FBA):

I ship my products myself (MFN - Merchant Fulfilled Network)

Important: If using the repricer (add-on), set Fulfillment channel code to DEFAULT and map Quantity to your stock. Failing to do so can feed the repricer incorrect data and block repricing.

1. In Build, click Attributes per category.

2. Select a category and scroll to the Offer section.

3. Next to Fulfillment availability, click + Add:

   1. For Fulfillment channel code: Static values > DEFAULT

   2. For Quantity: select your stock field

   3. For Handling time: if it takes longer than 2 days to ship, fill in the number of days (e.g., 5). If under 2 days, leave empty.

4. For Merchant Shipping Group: map your shipping template ID if used.

5. Map any remaining mandatory fields to corresponding fields from your data.

   1. If selling on Amazon US and Item Type Keyword appears in “Information to uniquely identify your product”, choose Internal fields > recommended_browse_nodes.

6. Repeat for each category.

7. Go to the Quality step and resolve any flagged errors.

Tip: Click Auto-map fields to automatically map using information using information from your other channels or other similar setups. Learn more.

Amazon ships my products (AFN / FBA)

Important: If using the repricer (add-on), set the correct Amazon warehouse code in Fulfillment channel code (e.g., AMAZON_EU). Do not map Quantity. Failing to do so can block repricing.

1. In Build, click Attributes per category.

2. In the Offer section, next to Fulfillment availability, click + Add:

   1. Set Fulfillment channel code to the Amazon warehouse code (Static values > [your relevant Amazon code]).

   2. If selling on Amazon US and Item Type Keyword appears, set Internal fields > recommended_browse_nodes.

3. Map any remaining mandatory fields.

4. Repeat for each category.

5. Go to Quality and resolve any flagged errors.

Note: Some attributes are required by Amazon even if they don’t make sense for your product. In such cases, choose a relevant static value or map the most appropriate import field.

Tip: Click Auto-map fields to automatically map using information using information from your other channels or other similar setups. Learn more.

Connect to Amazon

1. Return to the Settings step.

2. For Linked seller account, click Select seller account.

3. Click Amazon and fill in the requested information:

   1. For Label: Name your connection

   2. For Region: Choose Europe (for EU countries and UK) or North America (for US, Canada and Mexico), Australia, UAE or Turkey

4. Click Connect with Amazon. You’ll be redirected to your Amazon Seller account to finalize the connection.

7

Test your channel 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.

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

8

Activate your channel

Important: Amazon processes data more slowly between 12:00–17:00 UTC. Change your schedule settings to run outside this window. Runs that take longer than 2 hours will auto-stop and need to be restarted.

1. In [your Amazon channel], go to the Settings step.

2. Click Activate API.

3. Click Save.

4. Click Run now to send product listings to Amazon.

Your channel will start creating/adding new listings and/or offers to Amazon. How long this takes depends on the amount of product data sent.

9

Review and fix listing errors

Amazon enforces strict data requirements. The Feedback tab shows issues (errors and warnings).

1. Go to the Result step of your Amazon channel and open the Feedback tab for an overview of all possible errors and warnings.

2. Return to the Overview tab to view product listing statuses and filter by:

   • Active listings: successfully listed

   • Inactive listings: listed but inactive

   • Incomplete listings: missing required info

   • No match found: not in Amazon’s catalog

3. In Feedback, start resolving issues, prioritizing submission errors:

   1. Click the red error code in Description to see details.

   2. Note the attribute causing the error (e.g., Item Weight) and click Go to attribute to jump to it.

   3. Re-map the attribute: choose a recommended value, a project field, or a manual value.

   4. Click Save.

4. Repeat for any other errors.

5. Click Run now to resend your products to Amazon.

Error types explained

Errors indicate an issue occurred which prevented the submission from processing. (e.g. a validation error.)

We detail all the possible error types you can encounter below. For information on how to solve a specific error, refer to our Amazon error troubleshooting guide.

Submission errors (important)

Submission errors happen when Amazon encounters issues processing your product data after you send your listings.

Important: If one of your products has a submission error, it can have a cascading effect and prevent other products from processing. Because of this, prioritize fixing submission errors before addressing other errors.

Listing errors

Listing state errors are additional errors we request from Amazon to make sure you have all the information you need to go live and optimize your listing. Because we pull all possible errors, some listing state errors aren’t relevant to and can't be resolved within Channable.

Note: If you notice a product with a listing error is updating as it should on Amazon, you can ignore the error, but fixing listing state errors can improve your listing quality.

Warnings

Warnings indicate an issue occurred that should be reviewed but hasn't prevented the submission from processing.

Note

• Dry runs clear submission errors (useful for testing) but only normal runs keep full feedback history.

• Some listing state errors stem from older Amazon API versions (V1) and cannot be resolved via standard API use on V2. Amazon is working on fixes.

If you encounter this, try deleting listings with the error by removing their SKUs from your channel. Wait 24 hours, then resubmit the listing.
