Choosing to use the "EAN Matching" method allows you to match and therefore directly link your offers (your prices and stock, retrieved from your catalog data) to the already existing products of the channel.
This saves you from having to create a product file which would require more settings (adding a description, images, titles, etc...).
✅ On Lengow, the prerequisite which is common to all channels allowing EAN Matching is to have associated your product with the category asked by the channel, at the Category Matching step in Lengow.
✅ Additional prerequisites are specific to each channel.
Find below all the channels who accept to receive product creations/updates via a "EAN Matching" setting and their technical requirements in Lengow.
