Starting the week of August 10, 2026, Vertbaudet is making discount period dates mandatory for all discounted offers on their French (VBFR) and German (VBDE) channels.
What is changing?
Whenever an offer includes a discounted price (discount-price), the following fields will become mandatory in your offer feed:
discount-start-datediscount-end-date
Important Warning
If either the start or end date is missing on a discounted offer, Mirakl will reject the offer in error. This applies to both the VBFR and VBDE channels.
Scope and Impact
This update strictly applies to offers where a "discount-price" is actively sent in the feed. Please note the following nuances:
- New or updated discounted offers: Will be rejected if the dates are missing.
- Non-discounted offers: Are not affected by this change.
- Previously discounted offers: If they are not updated or re-sent in the feed, they will not be rejected.
Action Required
To avoid offer rejections, please review your Vertbaudet field mapping in Lengow. Ensure that whenever you map a value to "discount-price", you also map valid dates to both "discount-start-date" and "discount-end-date".
