Connecting a marketplace means giving Osello access to your seller account there. Once connected, Osello loads that marketplace's categories and field requirements and starts syncing — from then on, listings, offers, and orders all flow through Osello.
Start the connection
- In the sidebar, click the + button next to the Marketplaces heading.
- Pick your marketplace — for example Target+, Macy's, Nordstrom, or Bloomingdale's.
- Fill in the form and save.
What the form asks for
- Name — what this connection is called in your sidebar. The marketplace's own name is a fine default.
- Credentials — the keys that let Osello act on your seller account. These come from your seller account on the marketplace itself; for example, Target+ asks for a Seller ID (SMS ID) and API Token, while Macy's and similar marketplaces ask for a Store ID and Personal API Key. The per-marketplace guides below show exactly where to find them.
- Offers and Orders settings — whether Osello pushes prices and inventory, and whether orders sync. The defaults are right for almost everyone; you can change them later.
- A newly connected marketplace starts with Pull Orders & Updates on and Push Order Updates to [marketplace] off, so orders flow into Osello for visibility while the marketplace keeps control of accepting them. Turn Push Order Updates to [marketplace] on once you're ready for Osello to answer the marketplace for you — see Accepting and rejecting new orders.
- Push Orders to Integrations is a separate switch that decides whether this marketplace's orders are created in your Shopify store (or another connected integration) and kept updated there. It only applies while Pull Orders & Updates is on — see How marketplace orders reach you.
- Source Product Filters — optional tag or SKU filters if only part of your catalog belongs on this marketplace. Leave these blank to start; you can always narrow later.
What happens after you connect
- Osello loads the marketplace's category tree and field requirements — the rules your listings will need to meet. You'll find them under the marketplace's Categories and Fields pages in the sidebar.
- The marketplace gets its own sidebar section with Listings, Offers, and everything else you'll use day to day.
- Osello begins syncing with the marketplace automatically on a regular schedule.
- Your existing orders are pulled in. The first time a marketplace connects, Osello pulls in every order placed on that marketplace in the past year, so orders you already had there show up on your Orders page. Orders older than a year aren't imported. This happens once, on the first connection; if the marketplace ever disconnects and you reconnect it, Osello picks up where it left off instead of re-importing everything.
From there, the next step is creating listings from your products.
Connecting takes minutes; approval can take longer
The Osello side is quick. What varies is the marketplace: some seller accounts need to be approved or have API access enabled before the credentials work. The per-marketplace guides cover what to expect for each one.
