Error message: "700001 - MOIN_ALREADY_KNOWN"
This error means that a similar product is already offered on OTTO by another partner. You need to check that the product returned via the provided link perfectly mapes your product:
- If it's not the same product, you have to open a ticket request with Otto so that an analysis can be performed on their end.
- If it's the same product, validate the offer in your Otto backoffice - this cannot be done automatically through Lengow. You then need to set the MOIN identifier of the product in Lengow, in the "moin" attribute.
