Amazon error message (examples)
purchasable_offer.0.discounted_price.0.schedule.0: 'end_at' is a required property
purchasable_offer.0.discounted_price.0.schedule.0: 'start_at' is a required property
What does this error mean?
This error means that the start and/or end date of the promotion is missing or provided in the wrong format.
If you are sending a discount price to Amazon, you must also send the start and end dates of the promotion, as these three attributes are mutually dependent:
- "purchasable_offer..discounted_price..schedule..value_with_tax" (reduced price)
- "purchasable_offer..discounted_price..schedule..start_at" (start date)
- "purchasable_offer..discounted_price..schedule..end_at" (end date)
How to fix this error
In Lengow, make sure that when setting up a promotion, you also provide the promotion start and end dates.
The expected date format is: yyyy-mm-dd. Example: 2025-05-30
