Store Integration with Allegro
Key facts
- We connect WooCommerce with Allegro in two ways: through BaseLinker (cheaper and faster, usually 1-2 weeks) or straight through the Allegro API (a dedicated module, a few weeks).
- As a rough guide: a connection through BaseLinker is PLN 3,000-8,000 net, a custom module on the Allegro API PLN 8,000-20,000 net. Support after go-live starts at PLN 300 net per month.
- The result is the same: one warehouse for the store and Allegro, one order queue, one packing process.
- Scope: listing and updating offers from the store product records, mapping Allegro parameters and categories, syncing stock and prices, pulling orders, Allegro Smart and delivery methods, automatic courier shipments, sales documents.
- Integration straight through the API makes sense with a large number of offers, unusual parameters or your own warehouse system. At a smaller scale BaseLinker is enough.
- After the analysis we say plainly which route is cheaper in your case, and we quote both.
Allegro can bring in most of your turnover, but run next to a store it turns into a second company: separate stock, separate orders, separate shipments and constant watching so the same item is not sold twice.
We connect WooCommerce with Allegro – usually through BaseLinker, sometimes straight through the Allegro API if the scale or an unusual product range calls for it. The result is the same: one warehouse, one order queue, one packing process.


Through BaseLinker or straight through the Allegro API?
Through BaseLinker. Faster, cheaper and with no custom code. BaseLinker lists offers, pulls orders, generates labels and watches stock. For most stores this is the right choice and that is what we usually do.
Straight through the Allegro API. It makes sense when you have very many offers, unusual parameters, your own warehouse system or you need logic that cannot be set up by clicking. Then we write a dedicated module.
We do not push an expensive solution when a cheaper one is enough. After the analysis we say plainly which route makes more sense in your case and what each of them costs.
How does the rollout work, step by step?
Shared stock
One stock level for the store and Allegro, with a reservation on each order. No more selling an item that has just gone out through the other channel.
Offers from the store range
Listing and updating offers from the product records in WooCommerce, together with parameters, photos and prices.
One shipping process
Orders from both channels land in the same place: packing, labels, tracking numbers and sales documents.
What does the Allegro integration cover?
Listing and updating offers from the products in the store, with mapping of Allegro parameters and categories.
Stock and price sync between the store, Allegro and the other sales channels.
Pulling orders from Allegro together with invoice data and the chosen delivery method.
Allegro Smart and delivery methods – correct mapping of shipping rates and pickup points.
Automatic shipments with couriers: InPost, DPD, DHL, GLS, Poczta Polska.
Sales documents – invoice or receipt, also in a setup with Subiekt or Comarch Optima.
When is it worth connecting the store with Allegro?
Sales on Allegro are growing and stock in the store is watched by a person with a spreadsheet.
Offers are listed by hand and after every price change they have to be fixed twice.
Orders from Allegro are retyped into the system just to issue an invoice.
The store is only being built and Allegro is already running – the two have to be joined without stopping sales.
The integration is there, but it was built by someone who no longer answers the phone.
Frequently asked questions
How much does an Allegro integration cost?
A connection through BaseLinker is roughly PLN 3,000-8,000 net. A custom module on the Allegro API, for a large number of listings or unusual rules, is usually PLN 8,000-20,000 net. Allegro commissions and the BaseLinker subscription are costs on your side. Support after go-live starts at PLN 300 net per month.
Do I need BaseLinker?
Not always, but in most cases it is the cheapest and fastest route. Integration straight through the Allegro API makes sense with a large number of offers or unusual logic – then we say so plainly and quote it separately.
Will stock be up to date in real time?
In practice yes: the sync runs in short cycles and stock is reserved when an order comes in. A window of a few seconds always remains, so for one-off items we set an extra buffer.
What about offers that have no counterpart in the store?
We leave them out of the sync or create technical products for them in WooCommerce. We settle that at the product mapping stage.
How long does it take?
Connecting through BaseLinker usually takes 1-2 weeks. A dedicated module on the Allegro API is a matter of a few weeks, depending on the number of offers and the rules. Quote after the analysis, free of charge.
