Every channel connects from Integrations → Marketplace → Add New Marketplace. What differs is the authorisation step and what the channel exposes afterwards.
How each channel authorises
Sign in on eBay and approve. Business policies and category aspects come across with the connection.
Authorise from Seller Central. FBA, FBM and multi-marketplace accounts are supported.
Install the Huup app in OTTO Partner Connect and authorise. No keys to copy.
Authorise Huup from Temu Seller Center. Grant every permission the screen asks for, because the set is fixed at that moment.
A two-step key setup covering the UK site and OnBuy's European country sites.
Standard OAuth, with personalisation fields supported natively.
Wholesale-oriented: MOQ, tiered pricing and RFQ rather than single-unit retail.
What the first sync brings in
- Existing listings, matched to Huup products by SKU where possible.
- Recent orders, with items, addresses and payment status.
- Channel reference data — categories, attributes, approved brands and shipping profiles.
Get SKU mapping right on day one
Huup matches a channel listing to a product by SKU. If a channel listing carries a different SKU — or none — it arrives unmatched and stock will not sync to it. Fixing this at import is minutes of work; fixing it after an oversell is not.
