E15059 — WhatsAppInteractiveCarouselButtonsMismatch
The carousel's cards do not all carry the same buttons.
- HTTP status: 422
- Type: validation_error
- Name: WhatsAppInteractiveCarouselButtonsMismatch
What to do
WhatsApp renders one carousel, not a set of independent cards, so every card must offer the same kinds of button in the same number. Give each card either one cta_url button or the same count of reply buttons, and use the same choice on all of them. The labels and the links may differ per card; the shape may not.
