Error message
REQUEST_REJECTED_API Price update rejected due to validation errors.
What does this error mean?
This error occurs when Zalando rejects your price updates because the dates sent for your promotions (scheduled prices) are obsolete (past dates) or redundant compared to currently active promotions.
How to solve it
To fix this error, you need to adjust the mapping of your promotional prices. Follow these steps:
Check the dates: Identify the affected products and verify the values provided for your scheduled price attributes (specifically "scheduledPriceStartTime_01" and "scheduledPriceEndTime_01").
Clean the mapping: Remove the values for these dates in the Attributes Mapping in Lengow so that obsolete dates are no longer sent to Zalando.
Resynchronize your feed: Once the mapping is updated, launch a full export (manual full push) to synchronize the prices and send the corrected data to the marketplace.
