Changes in Allegro from May 26th – the product catalog becomes the primary one. IdoSell is now ready
What?
Allegro is introducing the requirement to use catalog data for some new listings starting May 26, 2025.
Why?
The changes are intended to increase the consistency of product data and make it easier for customers to compare offers.
Who's it for?
For Allegro sellers, online store owners, and integrators like IdoSell.
Background:
Starting May 26, 2025, Allegro will automatically accept product data from its own catalog as superior to data entered by sellers. Parameters marked as "trusted" will be retrieved directly from the catalog, limiting user editing. IdoSell was one of the first platforms to announce that it had adapted its integration to these principles, ensuring a smooth listing process.
Why does this change matter for the digital world?
This change is part of a broader trend of automation and data standardization in e-commerce. Trusted parameters allow customers to receive consistent information regardless of the offer, which can increase conversions and reduce returns. For retailers, this means adapting their systems and processes to the established standards.
What are the benefits for sellers?
– Increased compliance of offers with platform requirements.
– Improved visibility of offers in search results.
– Reduced risk of errors in product descriptions and parameters.
– Faster listing of offers thanks to automatic data completion.
What has changed in IdoSell integration?
IdoSell quickly responded to Allegro's announcement and modified its data synchronization mechanism. For parameters marked as trusted, data will be automatically downloaded from the Allegro catalog, eliminating the need to manually enter it in the IdoSell panel. This ensures that the listing process will not be disrupted after May 26th.
Will the changes affect the daily operations of companies?
Yes, sellers must adapt the way they prepare offers. However, integrations like IdoSell help minimize operational effort. It's important to monitor which categories and parameters will be subject to mandatory review and prepare your team for the new cataloging rules.
