How to connect Amazon to Nembol (video)

Exceptions

  1. Nembol works with most but not all Amazon locales. There may be exceptions due to Amazon platform mechanics: please test with your own Amazon Pro Seller account.
  2. You need to be an Amazon Pro Seller to connect Nembol to Amazon (i.e. you must be paying Amazon a monthly subscription).
  3. Nembol does not work with Amazon Handmade at this time.
  4. All products must have a genuine GTIN to list or sync with Amazon. No barcode exemptions work at this time.
  5. Nembol creates new Amazon product detail pages for single-variant products only. A product with variations can be published only onto a detail page that already exists in Amazon’s catalog.
  6. Imported content from Amazon may be incomplete. Amazon typically returns only the content attributed to the seller, as it centralizes product information such as pictures and descriptions. Empty fields may result for products with no seller-provided content, or those products for which Amazon has substituted information over time.
  7. FBA products: Nembol imports FBA (Fulfilled by Amazon) product quantities, along with images, prices, and other product details provided by Amazon. Sellers can then publish their FBA products to other supported sales channels and enable MCF (Amazon Multi-Channel Fulfillment) to fulfill orders across those channels using Amazon’s inventory.
  8. Amazon may take time to process updates. Price and quantity updates are usually reflected within 10–15 minutes. Other content changes, such as titles, descriptions, or images, may take 2–8 hours. Because Amazon controls centralized product content, updates may be reviewed and not all changes are guaranteed to be accepted.

Let's connect your Amazon to Nembol

  1. Make sure you’re logged in to your Amazon Seller Central with the same browser that you are using with Nembol
  2. Go to the Channels Tab in Nembol
  3. Click on “Connect channels +” top left. A list of available channels will appear beneath 
  4. Find Amazon, and click on it. On the overlay window, select your Seller Central country, then click “Connect”. You will be redirected to Amazon Seller Central, where you have to log in using your Pro Seller username and password
  5. If you have multiple Amazon Merchants, you will be asked to pick one. Select your main Marketplace as well -> See the Screenshot 1
  6. Authorize Nembol and click on Confirm -> See the Screenshot 2
  7. Once you clicked “Confirm”, you will be taken back to Nembol and the Amazon settings will open. Let’s setup now!

Screenshot 1: Within Seller Central, please select the correct Merchant, if you have more than one, and the correct Marketplace.

Screenshot 2: Authorize Nembol to access and view some of the information within your Amazon Pro Seller account.

Common settings setup: Amazon

In Nembol you can find settings which are common to all channels, called Common Settings, and settings which are specific channel by channel.

Sync stock from a channel

When an order is received

Enable Amazon if you want stock quantities in Nembol to be updated when an order is received on Amazon. Every time a sale is completed on Amazon, the order information is sent to Nembol, triggering a stock adjustment that is then synchronized across all connected sales channels.

Disable this option if you do not want Amazon orders to affect stock levels in Nembol.

When stock is edited

Choose whether stock changes made on Amazon should update quantities in Nembol. This includes manual inventory updates performed directly on Amazon as well as automatic adjustments generated by external applications or integrations connected to the marketplace.

Push updates to channels

Select Amazon if you wish to edit your listing details from Nembol centrally, and have those edits syndicated to your corresponding Amazon listings. With this setup, when you edit a listing in Nembol: change a description, edit title, tags, or pictures, and click save, those edits will update your Amazon listing, if so Amazon will allow (read box below).

Unselect it if you don’t wish to update your Amazon listings from Nembol.

Please note: Amazon uses a shared product catalog, where product content is centralized across all sellers. Therefore, any content updates sent from Nembol are subject to Amazon’s review process.

Most sellers do not own the product content on Amazon. If your edits are not applied, it may be because Amazon has rejected the update or another seller’s content has priority for that product listing. This is expected behavior on Amazon and is not a Nembol synchronization issue.

Add images for Amazon product variations

Nembol supports variant images on Amazon. Amazon allows each child ASIN to have its own independent image set. This means every variant can display a dedicated main image plus additional images specific to that variation.

To assign variant images in Nembol:

  1. Open the Products tab.
  2. Click on the product and select Edit.
  3. Scroll down to the Variants section.
  4. Select the variant you want to update and upload its images.
  5. Repeat the process for each variant, then click Save & Update.

When the listing is published, Nembol automatically maps the images to the corresponding Amazon child ASINs. Amazon supports up to 9 images per variant (1 main image and up to 8 additional images), allowing each variation to maintain its own visual gallery independently from the others.

Make sure Push updates to channels is enabled if you want image changes made in Nembol to sync automatically with Amazon. 

Publish to Amazon

How Amazon product listings are structured

An Amazon product listing is made up of two connected parts: the product detail page and the seller’s offer.

  • Product detail page describes what the product is. It belongs to Amazon’s catalog and contains information shared by all sellers offering that product, such as the title, description, images, and product specifications. Sellers do not create a separate page for the same product; instead, they add their own offer to the existing page.
  • Seller offer defines how that seller is selling it. This part is controlled by each individual seller. It includes details such as the selling price, available inventory, product condition, fulfillment method, and shipping options.

Each product detail page is identified by an ASIN.

ASIN is Amazon Standard Identification Number. An ASIN represents a specific product or variation in Amazon’s catalog. Multiple sellers can offer the same ASIN, competing with each other through their individual offers.

How Nembol publishes products on Amazon

  • Products with an ASIN: If Amazon’s catalog already has a detail page for your product, Nembol attaches your offer to that page.
  • Products without an ASIN: If no detail page exists, Nembol creates one and then attaches your offer to it.

How to check if a product already has an ASIN

You do not have to check in advance: Nembol tells you after your first publish attempt. If you would rather know beforehand, you can search Amazon’s catalog yourself:

  1. Sign in to your Amazon Seller Central account.
  2. Open Amazon’s product search.
  3. Search by barcode — GTIN, EAN, UPC or ISBN — or by the product name or brand.

If Amazon returns a match, that product already has a detail page and an ASIN, and your product will be published as an offer on it. If nothing matches, Amazon has no detail page for the product, and Nembol will create one when you publish.

Searching by barcode is the more reliable check: names and brands can match products that are not yours.

Publishing products that already have an Amazon ASIN

Amazon recognizes your product from its ASIN, or from a barcode — GTIN, EAN, UPC or ISBN — that already points at a detail page in its catalog.

When there is a match, publishing is straightforward: Nembol sends your offer — price, inventory, condition, fulfillment method and shipping — and Amazon attaches it to the existing detail page. Nothing extra is asked of you.

The title, description, images and specifications stay as Amazon holds them. They belong to the detail page, which you share with every other seller offering that ASIN.

You enter the ASIN in the product’s Inventory tab, or from the Products tab by clicking Edit and opening the Inventory section.

Publishing products that don’t have an Amazon ASIN yet

If you try to publish a product that does not have an ASIN yet — meaning Amazon does not have a detail page for it — the publishing process will pause.

Before Amazon can create the listing, you need to provide some additional product information in Nembol. The required details depend on the Amazon category you are selling in and help Amazon understand what the product is, what it is made of, and who it is intended for.

Open the product in Nembol, complete the required details, and publish it again.

Step 1 — Confirm the product type
Open the product and go to its Amazon card in the Listings tab. Nembol suggests an Amazon product type based on your product title. Check that it is correct and change it if needed. This step is important because the product type determines which details Amazon requires.

Step 2 — Fill in the product details
Once the product type is confirmed, the required fields appear below it. Many fields are already populated using the information from your Nembol product, so you may only need to complete a few additional details. Fields required by Amazon are marked as mandatory; optional fields can be left blank.

Step 3 — Publish again
After completing the required fields, publish the product again. Nembol sends the information to Amazon, Amazon creates the new detail page, and your offer is added to it.

IMPORTANT:

You still need a valid barcode
Amazon requires a valid GTIN for the product, and Nembol does not support Amazon barcode exemptions. If your product does not have a barcode, you need to obtain one before Amazon can accept the listing.

Products with variations
Currently, Nembol creates new Amazon detail pages only for single-variant products. Products with variations cannot create a new detail page and can only be published if the corresponding Amazon detail page already exists.

Please note: creating a detail page is a request to Amazon, not a guarantee. Your Amazon account must be in good standing, and even with every required field completed, Amazon reviews new detail pages and can still reject the listing. Approval is Amazon’s decision, not Nembol’s.

Before your first publish, set up a few things in Amazon publish settings:

  1. Select the Shipping Template. Leave the field blank and Nembol will list your products using the Default Shipping Template defined inside your Amazon Seller Central. If you otherwise wish to use a specific Shipping Template, type in the field its exact name. Best if you copy-paste it from your Seller Central account. Make sure the name in Amazon and Nembol are identical, otherwise the listing will return an error. Once chosen, the Shipping Template will be applied to your next listings. Any change you make now won’t affect your previous listings.
  2. Set condition. Set which condition you wish to list on Amazon: new, used, or others from the list
  3. Set pricing rules. Choose whether to apply the Pricing rules to your Amazon listings. Read here how to use Pricing rules ->

Import from Amazon

You can choose from which Marketplace you wish to import your Amazon listings into Nembol, and then list them on multiple channels: eBay, Shopify, Etsy, WooCommerce, Meta, and other supported channels.

By default, when you click Import, Nembol imports ALL the products in your Amazon account, including sold-out and inactive items. 

To exclude sold-out items, set an Import quantity filter (e.g. quantity more than 0) in Channels tab → Amazon → Import settings before importing. 

There is no filter by listing status, so inactive listings that still have stock will be imported.

Screenshot 4: Import from Amazon settings inside Nembol.

Please note: When Nembol imports products from Amazon, some product information may be incomplete. Amazon uses a centralized catalog system and only provides sellers with the content they are authorized to manage.

As a result, some fields (such as images, descriptions, or other product details) may appear empty if:

  • the seller has not contributed content for that product, or
  • Amazon has replaced the seller’s content with information from another source over time.

This is expected behavior from Amazon’s catalog system and does not indicate an issue with Nembol.

Fulfilment: Amazon FBM, FBA, MCF

A seller can choose to ship their products independently, or otherwise to provide a stock to Amazon and require Amazon to ship on their behalf.

The latter service has costs, mechanics, pros, and cons which we will investigate in another article.

  • When products are shipped by you, the seller, Amazon calls those products FBM — Fulfilled By Merchant.
  • When you entrust Amazon to ship for you, Amazon calls those products FBA — Fulfilled By Amazon.
  • When you ask Amazon to ship your FBA orders received from other channels, like eBay or Shopify — Amazon Multi-Channel Fulfillment.

To use FBA services, a seller has to ship an initial stock to some Amazon’s warehouse, and replenish this stock as long as inventory sells. It will be Amazon taking care of picking, packing, and shipping, and of course it will be Amazon’s systems taking care of reducing the remaining stock each time an order is actually shipped.

Nembol though gets FBA stock quantities from Amazon’s systems when a seller imports products from Amazon into their Nembol account.

Therefore, each seller using Nembol is free to publish their FBA products, with the correct stock count, on any additional channels they wish, among those serviced by Nembol.

Amazon MCF: how to activate it on Nembol

Nembol includes a beta integration with Amazon Multi-Channel Fulfillment (MCF), allowing you to use Amazon’s fulfillment network to ship orders received from other connected sales channels, such as eBay, Shopify, WooCommerce, TikTok Shop, OnBuy, Square, Squarespace and Wix.

When enabled, orders placed on these channels can be automatically transferred to Amazon MCF for fulfillment. Amazon will then handle the picking, packing, and shipping process using the inventory stored in your Amazon fulfillment centers.

To activate Amazon MCF in Nembol:

  1. Open the Channels tab.
  2. Select Common Settings.
  3. Under Transfer orders for fulfillment, choose your Amazon account (See screenshot below)
  4. Configure Sync stock from a channel:
    • In When an order is received, enable Amazon together with the sales channel where you receive orders (eBay, Shopify, WooCommerce, TikTok Shop, OnBuy, Square, Squarespace, or Wix).
    • In When stock is edited, enable Amazon to sync inventory updates and keep stock levels in Nembol aligned with the quantity currently available in Amazon MCF.
After these settings are configured, all future sales should sync automatically.
