What you get with M&S Marketplace and Salync.
Mirakl API integration
Connects to your M&S Mirakl account using your API key - no manual file uploads or exports needed.
Instant quantity sync
A sale anywhere triggers an immediate push to M&S so offer quantities are always current.
Batched offer updates
Up to 100 offers are processed per API call, keeping sync fast without exceeding Mirakl rate limits.
Unified stock pool
Share one stock pool across M&S, Shopify, John Lewis, Next, and every other connected channel.
Shop SKU mapping
Enter your M&S Mirakl Shop SKU on each product listing - Salync does the rest automatically.
Audit trail
Every push is logged with timestamps so you can investigate discrepancies and prove sync accuracy.

Questions about M&S Marketplace.
Is M&S Marketplace open to all sellers?
M&S Marketplace is invite-only and curated. You need to apply and be approved before you can list.
Does Salync create M&S listings?
No - Salync syncs stock quantities on listings you already have. Listing creation is done in your M&S Seller Admin.
What happens if stock runs out?
When quantity reaches zero, Salync pushes 0 to M&S, hiding the offer automatically - preventing overselling.
Can I connect M&S alongside other marketplaces?
Yes. Salync is designed for this. Connect M&S alongside John Lewis, Next, ASOS, Currys, and more from one dashboard.
How do I find my Mirakl Shop SKU?
Log in to M&S Seller Admin, go to your offers list, and look for the "shop_sku" column. That's the identifier Salync needs.
