How to Set Up Shopify Marketplace Connect

Marketplace Connect puts your Amazon, eBay, Walmart and Target Plus listings, orders and stock in one place, inside your Shopify admin. Setting it up spans three places, your Shopify admin, the app and the marketplace's own seller account, and the order matters: approval first, then the connection, then the defaults, and only then the listings.

This guide follows that order. It keeps Shopify's Help Center apart from the app's own help site, which documents several settings the Help Center doesn't, and it says which of the two each rule comes from.

What Marketplace Connect Does and Where It Works

Shopify's Help Center describes Shopify Marketplace Connect, formerly Codisto, as the app that connects your product catalog to several marketplaces and lets you manage and sync all your orders, listings and inventory in your Shopify admin. You can sell in any region and in any currency your chosen marketplace offers, and built-in currency conversion shows your prices in each marketplace's local currency.

As of November 8, 2026, the Help Center lists four marketplaces you can connect. Find yours in the table; the sections below hold the detail behind each cell.

Etsy isn't on the list. A note on several of the section's pages says new connections to Etsy can't be made at this time, and that stores already selling on Etsy through Marketplace Connect can continue to use the app; none of the pages we read gives a date or a reason. If you're starting an Etsy link now, our guide to connecting Etsy without Marketplace Connect covers the route that's left.

Marketplace Connect is an app you open from Apps in your admin, and Shopify's overview of marketplace sales channels lists it as one entry: a single app for listing products on marketplaces such as Amazon and Walmart. If you're unsure how that differs from a channel you publish products to, our sales channels guide starts with exactly that question.

What You Need Before You Connect

Two gates stand before the first listing, and you check them in different places: your Shopify admin for the store requirements, and the marketplace's seller account for approval. A third rule, one connector at a time, decides whether you start clean or migrate.

The Shopify side: four store requirements

Shopify's requirements page lists what the store needs before Marketplace Connect can work:

• A Shopify online store, with store access not set to private mode.
• A valid payment provider activated in your Shopify admin.
• Shipping rates for the countries you want to sell to, and payments accepted in a currency supported in each of them.
• A verified seller account on the marketplace you want to connect.

The Help Center's Marketplace Connect pages we read name no minimum Shopify plan, no list of supported store countries and no restricted product types for the app (search boundary at the end of this guide), so the conditions to check are the four above and the marketplace's own rules.

The marketplace side: an approved seller account

Shopify's setup page puts the marketplace side first: you need a verified seller account, approved to sell on that marketplace. Your store policies need to be visible on the marketplace according to its requirements, and when an order comes in, the payment comes from that marketplace, so it needs a payment method and bank account on file there. Each marketplace adds its own conditions:

• Amazon. Sign up for the seller account in the country you want to sell in. The app's help site adds that it must be a Professional account, not an Individual one, because Amazon doesn't provide API access for Individual accounts.
• eBay. The general rule applies: a verified seller account, approved to sell, with your store policies visible on eBay.
• Walmart (US marketplace). The app's help site says Walmart, unlike Amazon and eBay, requires special approval, and that the application may take approximately two weeks for Walmart to consider. It also says Walmart Marketplace is available only to customers in the US but is “not exclusive to US sellers”: international sellers can still be approved, and they must meet Walmart's additional criteria, which include a business entity registered in the US, a US-based warehouse and Walmart's specific US tax requirements. Walmart's own guide lists the minimum qualifications, including a business tax ID or license, marketplace or e-commerce history, GTINs or UPCs, US fulfillment and a catalog free of prohibited items, and warns that one prohibited item gets the application denied.
• Target Plus (US only). Shopify says to complete the Target Plus Seller Application form and then get approved to sell by Target Plus. Target's June 2024 announcement called Target Plus its invite-only marketplace and said US Shopify merchants can apply through Marketplace Connect. The app's setup article for new Target Plus merchants is for those who have received their onboarding email from Target, and on approval it says to refer to Target directly, because the app isn't involved in that part of the process.

Only one marketplace connector at a time

If another app already connects your store to a marketplace, the setup page is explicit about it:

The page states the rule for every store, and if you're switching to Marketplace Connect, it says to disconnect and uninstall your current connector app first. It makes no exception for a connector that serves a different marketplace.

Which Setup Route Is Yours?

The table above answers by marketplace. This quiz answers by combination, crossing your marketplace, your account status, your current connector and the listings you already have, and it returns the route to start on with its first steps.

The Setup Checklist, Step by Step

Steps 1, 3 and 4 apply to every route. Step 2 matters only if another connector is connected now, and your quiz route decides the weight of steps 5 and 6. Do step 4 before you list anything: Shopify says Amazon and eBay defaults apply to future listings, and existing listings aren't affected by them.

How Do You Install Marketplace Connect and Connect a Marketplace?

The setup page sets the order: install the app, check the requirements, add your first marketplace account, optionally connect others, and only then create listings for your products.

Connecting your first marketplace

Install the app from its Shopify App Store listing, which reads “Free to install. Additional charges may apply.”

Once it's installed, connect from your Shopify admin on desktop:

1. In your Shopify admin, go to Apps and open Marketplace Connect.
2. Click Connect account for the marketplace you want to connect to.
3. Follow the sign-in prompts for that marketplace to complete the connection.

On mobile, the same app opens from the Shopify app under Menu, then Apps. Target Plus is in the Help Center's list of marketplaces even though this screen doesn't show it; the app's Target Plus setup article starts from the onboarding email Target sends.

Amazon adds two conditions on the app's help site. The account must be a Professional seller account, and you have 15 minutes to complete the connection before the token expires. Once you're connected, the app opens its Amazon Connection Checklist, which runs through seller account status, SKU matching, barcodes and order import settings.

Shopify's own 2024 tutorial shows the Amazon connection and the linking of existing listings. The app's screens may have changed since it was recorded.

Adding a second marketplace or account

After the first account is in, go to Connect marketplace in the app and click Connect or Add for the next marketplace. The app's help site describes Marketplace Connect as a multi-channel app that supports multi-account and multi-site configurations from a single solution.

Each marketplace still needs its own setup. If you're connected to several, the Help Center says to repeat the listing steps for each marketplace where you want to add or edit a product, and each account keeps its own defaults.

Set Your Defaults Before You List

Defaults live per marketplace account, and each marketplace has its own set:

• Amazon, under Settings > Accounts > Amazon: the price rule, the quantity rule, and whether listings are fulfilled by Amazon (FBA) or by you.
• eBay, under Settings > Accounts > eBay > New listings > Manage: six defaults in the Help Center, namely price adjustments, inventory adjustments, shipping, return policy, auto categorization and auto-listing.
• Walmart: four in the app's help site, namely price, quantity, shipping (a Shipping Template ID and a Fulfillment Center ID) and auto-listing.

Which quantity rule should you pick?

The Help Center names three quantity settings for Amazon and eBay listings: a fixed value, a buffer and a maximum quantity. The app's own inventory settings article adds a fourth, Stock Level, which syncs your marketplace inventory to your current Shopify count exactly and updates it after an order on any connected marketplace or in your store.

A buffer is easiest to see in numbers. In Shopify's own example, a buffer of 2 on a product you hold 5 of makes the listing show 3. A maximum quantity of 5, in the app's example, always shows 5 unless your inventory drops below 5, when the listing shows the actual count.

No page we read names the rule a new listing starts with (search boundary at the end of this guide), so open the setting and choose one on purpose. The app's help site warns against a fixed quantity for products likely to go out of stock, unless you check stock levels regularly.

Stock Level syncs, but not instantly. The app's help site says updates are published immediately but typically take between 5 and 60 minutes to be processed by the marketplace, and it suggests a Quantity Buffer for fast-selling products. Its overselling article adds that larger catalogs are more prone to overselling because of the way syncing through the API works.

On Amazon, FBA orders don't change your Shopify inventory counts: only merchant-fulfilled (FBM) orders on synced products do, according to the same help site.

Price rules and price sync

The default Amazon price rule lets you choose a constant value, or a percentage or dollar increase or decrease relative to your Shopify catalog price, and apply price rounding if you want it. eBay's price adjustments offer the same set. The app's pricing settings article names four operators:

• Web Price: the marketplace price matches your Shopify price exactly.
• % Increase/Decrease: the Shopify price moved by a percentage.
• $ Increase/Decrease: the Shopify price moved by an amount.
• Fixed Price: one price you set.

The same article says pricing sync can't be turned off for individual products or groups of products. What you can do is set Marketplace Connect not to synchronize price or quantity on a marketplace you select, through attribute mapping, which turns that sync off for all your products there; it's the route the help site gives for stores that use a repricer or an inventory management system.

Shopify's channel markets, which set prices per sales channel inside Shopify, are a different tool. Our channel-specific pricing guide explains where the two part ways.

What else syncs: titles, metafields, images, location

By default, Marketplace Connect uses your Shopify product name as the listing title, and if you change the product name, the listing title changes automatically. To manage titles, descriptions and images directly on Amazon instead, turn off Send listing details in the bulk editor; on eBay, turn off image sync there to manage images on the listing itself.

All core Shopify product metafields are mapped automatically after setup, and you can create your own for data a marketplace requires. If two metafields share a name, the duplicate won't sync. The Help Center lists which metafield types the app recognizes:

Inventory location works at a coarser level than variants. You set it per product, for products in bulk or for a whole regional marketplace, and you can't configure it for specific product variants.

Link Existing Listings or Create New Ones

Shopify is the record here. The app's help site says Marketplace Connect doesn't import your listings to create products in Shopify, so the products must exist in Shopify first. After you connect a marketplace, you list those products to it.

Linking listings you already have

When a connected marketplace already has your listings, Marketplace Connect searches your store and suggests a Shopify product for each, based on the product's SKU, UPC or title. Orders and inventory start syncing only for the listings you link.

Suggestions carry one of three badges: Ready to list, Close match or No match. For a Ready to list item, click the link next to the badge; where no match is found, you choose the product yourself.

eBay asks one more question when you link. For five listing rules (shipping rules, return policy, eBay title, description, and price and taxes) you keep the eBay listing's own settings or use Marketplace Connect's. The Help Center is blunt about the second option: if you select Use Marketplace Connect settings, the original settings for the eBay listing can't be restored.

Shopify's 2024 tutorial walks through linking eBay listings in the app; its screens may have moved since.

On Amazon you don't need to end existing listings to start: the app's help site points you to linking them instead.

On Walmart, a product that's already for sale there, even if you're selling it for the first time, needs an offer to sell with price, inventory and shipping terms. Shopify's Walmart tutorial from the same series covers linking listings; it dates from July 2024.

Creating new listings from Shopify products

Shopify's product requirements say Amazon, Walmart, eBay and Target Plus require a unique product identifier for each product, such as a GTIN, UPC, MPN or EAN. Our guide to Shopify barcodes covers what Shopify does with a product's Barcode field.

• No GTIN for a product sold on Amazon? See how to get an Amazon GTIN exemption.
• The same question for Walmart: how to get a Walmart GTIN exemption.

The Help Center lists three listing modes:

• Single edit publishes one product: Listings, the marketplace, the product, Listing enabled, then Save.
• Bulk edit lists and manages several products or an entire catalog at once.
• Attribute mapping, the third mode, is also where the app's help site turns off price or quantity sync.

On Amazon, the app can create new listings, complete with new ASINs, directly from Shopify, and it suggests Amazon categories using Shopify's Standard Product Taxonomy. Every Amazon product has one listing page with one set of Listing content, its images, title, description and identifiers, while your price, quantity and fulfillment make up your Offer.

Connected isn't the same as live

The second gate is the marketplace's own acceptance, and the signal differs by marketplace:

• Walmart: the app's help site says that if the link goes green, your offer is live on Walmart. Errors can come back one round at a time, so check again after each fix.
• Walmart, Offer Only mode: a lighter mode that syncs only price, inventory and shipping.
• Target Plus: only critical errors will prevent an item from going live on Target.com, so fix those first.

How Marketplace Orders Reach Shopify

After an order is imported, it shows in the Orders section of your Shopify admin as though it was placed through your online store, with the marketplace's name in the Channel field. After you fulfill it, Marketplace Connect automatically syncs shipping status and tracking updates to the marketplace where the order was placed.

Order import settings and tax handling

Order import is set per marketplace account, under Settings > Accounts, the marketplace, then Order import and Taxes.

Tax handling decides what your Shopify reports show, and Shopify's Help Center makes Withhold tax the default:

The Help Center's import page adds that where the marketplace collects and remits the tax, Withhold tax imports the order to Shopify without tax in its details, and Send tax imports it with the tax included. With Withhold tax, taxes on marketplace orders don't display in your Shopify reporting, and you find them in the marketplace's reporting instead. With Send tax, marketplace order taxes display in your Shopify reporting. So, where your settings offer the choice, it comes down to where you or your accountant read marketplace taxes: in Shopify reports, choose Send tax; in the marketplace's own reports, Withhold tax already covers it.

On orders placed through Target Plus, Shopify says tax amounts won't be displayed in your admin. The app's help site describes tax differently from the Help Center. In an article edited November 5, 2026, it calls tax settings “now very simple”: if the marketplace sends the tax, the app sends it with your Shopify order, and if the marketplace collects and remits the tax, the app sets the order as channel liable. That article names neither Withhold tax nor Send tax, so check which options your order import settings show before you choose.

If an order wasn't imported automatically, import it by hand from Orders > Import in the app, then Save. Manual imports are unlimited and free, according to the setup page.

Fulfilling marketplace orders

Amazon gives you three ways to fulfill: through Shopify (FBM), Fulfillment by Amazon (FBA) or Multi-channel Fulfillment (MCF). Which one fits depends on your stock and margins, and our Amazon integration guide compares FBM, FBA and MCF.

Target Plus sets its own rules: you can ship only with UPS, USPS and FedEx, all orders over $35 qualify for free shipping, and returns are free and handled by Target Plus. For Target Plus orders you can't use fulfillment services through Amazon or Walmart.

If you use a third-party fulfillment app for orders from a connected marketplace, disconnect that marketplace from the fulfillment app to avoid duplicate orders there, then connect the fulfillment app to your Shopify store so those orders still reach it. The pages we read don't describe Walmart Fulfillment Services orders (search boundary at the end of this guide).

Returns, refunds and cancellations

Some things are left to you after a marketplace order goes wrong, and the first one affects your stock count:

• Restock by hand. Adjust the inventory yourself after a return or cancellation; the app's help site names one exception, an order canceled before it's paid, which is restocked.
• Cancellations. Some marketplaces let you accept return and cancellation requests automatically; otherwise log in to your marketplace account, accept the cancellation request there, and it syncs to Shopify.
• Refunds and returns. A refund marked in Shopify doesn't sync back to the marketplace, because Marketplace Connect can sync an order's status only once, and all returns or refunds must be processed through the marketplace.

How Much Does Marketplace Connect Cost?

Shopify's setup page lists three things with no charge: connecting and listing on all marketplaces, unlimited manual order imports, and the first 50 marketplace orders a month that sync automatically. For more synced orders it refers you to Shopify's pricing page rather than giving a figure.

The figures are on the app's side. As of November 8, 2026, the App Store listing linked above reads: first 50 marketplace-synced orders a month free, 1% fee per additional synced order, capped at $99 a month. The app's help site agrees: for managed marketplace listings, up to 50 orders import free each month, with a 1% charge on each additional order, capped at $99 per month, while orders from listings the app doesn't manage import free.

One detail differs between the app's own pages: which sales the 1% applies to. The listing and the app's What is Shopify Marketplace Connect article apply it to each additional order past the free 50, while the app's Billing article lists “1% of Gross Merchandise Volume revenue (sales)” for a month over 50 orders, without the word “additional”. We read all three on November 8, 2026:

The cap limits what the difference can cost you. The Billing article says the app prompts you to subscribe in a month with more than 50 orders from Shopify-synced listings, and then requests a billing agreement with $0 recurring and a usage cap of $99.

Read the charge terms in that request before you approve it; under either reading, the app's fee stops at the cap for the month. Our eBay integration guide covers what the app does and costs on eBay specifically.

Sync Problems and When Marketplace Connect Isn't Enough

For problems the table below doesn't cover, Shopify points you to the chat feature in the Marketplace Connect app for support.

Common problems and their fixes

When to look past Marketplace Connect

The app stops where its list does: Amazon, eBay, Walmart and Target Plus, with no new Etsy connections. A repricer or an inventory management system doesn't have to replace it, because you can switch off price or quantity sync and let the other tool set those values.

Catalog size is the harder call. No page we read sets a number of products past which Marketplace Connect stops fitting (search boundary at the end of this guide); the closest statement is the help site's note that larger catalogs are more prone to overselling. Treat overselling on a large catalog, after a buffer is in place, as the sign to look further.

Multichannel apps in the Shopify App Store cover more marketplaces. As of November 8, 2026, the Sellbrite listing describes selling on Amazon, eBay, Etsy, Walmart and more, the LitCommerce listing names Etsy, eBay, Amazon, TikTok Shop and over 20 marketplaces, and CedCommerce eBay Integration covers eBay alone.

Because Shopify says to keep one connector, picking one of them means replacing Marketplace Connect, not running beside it. Our Walmart guide looks at third-party multichannel apps.

Disconnecting a Marketplace or Removing the App

Disconnecting happens in the app's Settings section:

1. In Marketplace Connect, open Settings > Accounts.
2. Click the name of the account.
3. Click Disconnect account, then Disconnect.

The Help Center pages we read stop at the steps. The app's help site, in articles from 2023 that haven't been updated since, says canceling your subscription doesn't end your listings: they stop syncing with your Shopify store, and orders stop transferring to Shopify. If you reinstall within 7 days, your products sync again once you complete the onboarding checklist. A 2023 troubleshooting article on the same site, written for a reinstated Amazon account, says disconnecting and reconnecting the account in settings won't lose your listings.

If you're moving to another connector, keep the listings live and follow the order in the switching box, with Marketplace Connect as the app you disconnect first.

The Bottom Line

The app does the syncing. The decisions that keep it clean are yours, and most of them come before the first listing goes out.
