What a Mirakl-powered marketplace is
Mirakl is not a marketplace you join. It makes the platform that other businesses use to run their own marketplaces1. On a Mirakl-powered marketplace, the retailer is in charge. It runs the marketplace, approves its own sellers and sets any subscription and commission. You apply to the retailer, not to Mirakl.
What you sell there is an offer: your price and stock for a product in the marketplace’s catalogue2. Mirakl can match an offer to a catalogue product by its EAN2.
Mirakl’s own figures, in its words:
- Mirakl says it “helps a global ecosystem of 450+ marketplaces (B2C and B2B)” and “a network of over 100k third-party marketplace sellers”1.
- It reports “a record $14.6 billion in annual GMV on marketplace and dropship through Mirakl Platform” for 20251.
- Its sellers page counts “100k+” stores operated on Mirakl-powered marketplaces, with sellers based in “110+” countries3.
What Mirakl Connect is
Mirakl Connect is a separate Mirakl product for sellers. Mirakl’s developer portal calls it “a global Marketplace ecosystem bringing together sellers, partners and Mirakl-powered Marketplaces”4. Mirakl says sellers can use it to find new marketplaces and “apply directly”5.
invtri does not need Mirakl Connect. It connects each marketplace with the shop API key from that marketplace’s own seller back office, so you can run your Mirakl storefronts in invtri without it.
How sellers usually join a Mirakl marketplace
Each marketplace sets its own route and checks, and the names can differ. These steps follow Mirakl’s own seller onboarding guide for one UK marketplace6.
Apply, or accept an invitation
Apply through the marketplace’s own seller pages. If it invites you through Mirakl Connect, go to Business requests, choose the marketplace and click Create Store6. Either way, the marketplace decides whether to accept you.
Complete your shop settings
Fill in your shop details under Settings > Shop and provide the documents the marketplace asks for6.
Add your offers
The guide lists five ways to load offers: by hand, an Excel template, an Excel or CSV file, the API or a connector6.
Go live
A shop goes live once five checks are met: “Shop Settings Complete”, “All Documents Provided”, “KYC Complete”, “At Least 1 Offer Uploaded” and “Account information Complete”6.
Your shop API key
invtri connects to each storefront with a shop API key, which you create in that marketplace’s own Mirakl seller back office. Sign in as a user with the Shop Administration permission, which Mirakl’s guide says includes the “ability to call Shop API”6.
In the current back office, go to Profile icon > Personal settings > API key, click Generate new key and type GENERATE to confirm7.
The key sits under your personal settings, so it belongs to your user, not to one shop7. In invtri, each storefront connects with its own key, from that marketplace’s own back office.
Keep the key private, because software that holds it can act as your user8. invtri stores the channel connection keys you enter, including this one, encrypted.
Full steps: Find your Mirakl shop API key.
From retailer approval to synced sales
Apply to the retailer
Each Mirakl marketplace is run by its retailer. Apply on their Sell With Us page — approval, any marketplace subscription and commission rates are set by the retailer directly.
Get your Shop API key
Once approved, the retailer gives you a seller back-office. Generate your Shop API key there — invtri is BYOK, so your credentials and your revenue stay yours.
Connect the storefront
Add the storefront in invtri: pick the retailer from invtri’s Mirakl list if it’s listed, or choose Other Mirakl marketplace. Paste the marketplace’s API address and your shop API key, set the fee percentage, and test the connection.
List and import
invtri lists your products by EAN against the retailer catalogue and imports the offers you already have on that storefront — so existing sellers are managed from day one.
Sell and sync
Orders land in your ticket dashboard to accept, ship and track. Stock and prices push per storefront on your schedules, with oversell protection across every channel.
What the Mirakl channel gives you
- One connection, unlimited storefronts. Mirakl Marketplaces is one premium channel — connect as many approved Mirakl storefronts as you like under it at no extra cost per storefront.
- List by EAN. Your products are listed by EAN on each storefront, never guessed.
- Import existing offers. Already live on a storefront? One click pulls your current offers into invtri per storefront, so stock and price sync take over without re-listing anything.
- Orders with a safety guard. Orders flow into the same order tickets as every other channel. Optional auto-accept per storefront only fires when your stock covers the whole order — otherwise it waits for you.
- Per-storefront pricing and fees. Set a fee percentage per storefront and invtri prices each one through your margin rules. Commission from the marketplace feeds your channel profit reporting.
- No per-order fees from invtri. Your invtri licence is pay-once, plus monthly hosting. Whatever you sell across Mirakl storefronts, invtri takes no commission and no per-order fee.
Questions about Mirakl marketplaces
Is Mirakl a marketplace I can sign up to?
No. Mirakl makes the platform, and each marketplace on it is run by its own retailer1. You apply to each retailer separately, and it decides whether to accept you.
Do I have to join a marketplace through Mirakl Connect?
It depends on the marketplace. In Mirakl’s onboarding guide, you can create the store in Mirakl Connect or through a Shop Account Creation form sent by email6. Check with each marketplace which route it uses.
Do I need Mirakl Connect to use invtri?
No. invtri connects each storefront with the shop API key from that marketplace’s own seller back office, so you don’t need Mirakl Connect.
Does one API key work on all my Mirakl marketplaces?
No. Each key is created in one marketplace’s own seller back office, and API calls go to that marketplace’s own API address8. In invtri, each storefront connects with its own key; on that marketplace, one key can reach every shop your user has access to8.
How long does it take to start selling on a Mirakl marketplace?
It depends on the marketplace. Mirakl says sellers using Mirakl Connect onboard “in a median of 28 days”9, and the steps include the marketplace’s approval and KYC checks6.
Why do Mirakl orders need accepting?
Mirakl marketplaces ask sellers to accept or refuse each new order10. In invtri, these orders appear in your order tickets to accept or refuse.
I generated a new API key. What should I do?
Paste the new key into that storefront’s connection in invtri and test the connection. Mirakl asks you to type GENERATE before it creates a new key7.
