stock updates via Mirakl
Selling fashion on ASOS Marketplace alongside your other channels? Salync connects to your ASOS Mirakl account and pushes accurate stock quantities automatically, so popular items avoid overselling.
What you get with ASOS Marketplace and Salync.
Mirakl API integration
Connects directly to your ASOS Mirakl account using your API key - no manual exports needed.
Automatic quantity push
When a sale happens anywhere, Salync updates your ASOS offer quantities to match.
Batch sync
Push up to 100 offers per request to stay within the Mirakl rate limit while keeping all SKUs accurate.
Multi-channel awareness
Salync deducts stock across all your channels - so an eBay sale won't let an ASOS shopper buy the same item.
SKU mapping
Map your internal SKUs to ASOS shop SKUs on each listing - no need to rename your catalogue.
Sync history
Every push is logged so you can audit stock movements and diagnose any discrepancies.
How it works.
Apply to ASOS Marketplace
Sign up as an ASOS Marketplace boutique at marketplace.asos.com. Once approved you'll have access to the Seller Admin.
Generate your Mirakl API key
In ASOS Seller Admin go to Settings → API and generate a new key. Copy it - you'll need it in step 4.
Connect Salync
In Salync go to Channels → Connect Channel, select ASOS Marketplace, and paste your Mirakl API key.
Map your SKUs
On each product, go to the Channels tab and enter the Mirakl Shop SKU that matches your ASOS listing. Salync handles the rest.

Questions about ASOS Marketplace.
Do I need an existing ASOS Marketplace account?
Yes. You need an approved ASOS Marketplace boutique account. Salync uses the Mirakl API to sync stock - it doesn't create listings.
How quickly does stock update after a sale?
Salync pushes stock updates immediately when triggered - typically within a few seconds of the sale.
What if my SKU doesn't match the ASOS shop SKU?
That's normal. On each product's Channels tab, enter the exact ASOS/Mirakl Shop SKU. Salync sends that identifier to Mirakl.
Can I sync to ASOS and other channels simultaneously?
Yes - that's Salync's core purpose. Connect ASOS alongside Shopify, eBay, Etsy, or any other channel and all quantities stay in sync.
Is there a batch size limit?
The Mirakl API accepts up to 100 offers per PUT request. Salync handles batching automatically, so you don't need to worry about it.
