Shopify products list on Allegro with the parameters the marketplace requires, and Allegro orders and stock changes return, so one catalog serves both channels without duplicate listing work.
Merchants selling on Shopify who expand onto Allegro usually rebuild their catalog inside the marketplace. Without a live link, listings are created by hand against Allegro's category parameters, stock sold on Shopify stays live on Allegro until someone adjusts it, and marketplace orders are copied back into the storefront for fulfillment. Connecting Shopify and Allegro through Alumio publishes listings with their required parameters and returns orders and stock in both directions, so the same catalog trades on both channels without duplicated effort.

Shopify products publish to Allegro with the category parameters the marketplace expects, so a listing is prepared once instead of rebuilt inside Allegro by hand.
Stock sold on either channel updates the other, so a unit bought on Shopify stops being offered over on Allegro well before a second buyer can order the same item.
Allegro orders arrive alongside Shopify orders for picking and dispatch, so the warehouse works one queue rather than checking the marketplace panel separately.
Because listings and parameters are mapped once, adding a product range to Allegro is a configuration step rather than a fresh manual listing project per category.
When a product is ready in Shopify, Alumio creates the Allegro listing with the parameters its category requires, so the offer publishes without a merchandiser filling in marketplace attributes manually for every item.
When stock changes through a sale on either side, Alumio updates the other channel, so that Shopify and Allegro will always sell against the very same availability and the last unit is never promised twice over.
When an order is placed on Allegro, Alumio brings it into Shopify with its buyer and delivery details, so that it is picked and dispatched through the normal process and the tracking flows back to the marketplace.
Alumio sits between sales channels and fulfillment systems as a governed integration backbone. Orders are routed, transformed, and validated, while status updates return to every channel.
Authenticate your systems using Alumio's pre-built connectors. Choose from 200+ connector packages in the marketplace, plus unlimited custom integrations.
Define how data fields map between systems in a visual interface. Adjust formats, enrich records, and apply business logic, no custom code required.
Configure flows to run in real time on events, on a schedule, or both. Reduce manual data entry and let Alumio handle movement and transformation between systems.
Once your first integration is live, adding your ERP, PIM, WMS, or CRM connects to the same hub. Existing flows keep running. No rebuilding from scratch.
Yes. Sellers running Shopify with Allegro usually add an ERP or a courier integration next, since marketplace volume makes manual invoicing and label creation the next bottleneck. Alumio connects those from the same hub and reuses the Allegro order mapping already built, so a new system receives marketplace orders in the same structure.
Yes. Alumio publishes Shopify stock and price changes to Allegro and brings marketplace orders back for fulfillment. Stock updates can run frequently enough to prevent overselling during a promotion, while orders transfer as they are placed, so neither channel trades on a figure the other has already changed.
No. The manual work this replaces is creating each Allegro offer by hand and adjusting stock in the marketplace panel after every Shopify sale. Alumio holds the listing, parameter, and order mappings as configuration, so a new Allegro category or a changed parameter set is handled in the interface rather than in code.
Yes. Alumio maps Shopify product fields onto the parameters each Allegro category demands, so an offer publishes complete rather than being rejected for missing attributes. You configure the mapping per category, so a range that needs different parameters on Allegro than it shows on Shopify still lists correctly without a merchandiser completing marketplace attributes item by item.
Allegro can suspend an offer whose stock update never arrived, which costs visibility as well as sales, so Alumio surfaces the failure immediately. Every attempt is logged the moment it happens with the affected listing or order and its exact error, for example a category parameter the marketplace refused. Retries run automatically where you configure them, and an offer that stays unresolved escalates with its full error, so nothing disappears quietly.
