Review recent server attempts
Facebook Pixel + Conversions API settings summarize sent, skipped, and failed server event attempts from the last 30 days. Retries are counted separately and verification test events stay out of the totals.
Inspect a purchase outcome
Open a store order to see whether its purchase event was accepted by Meta, not sent for a stated reason, failed, or has no recorded outcome. An accepted earlier attempt remains visible if a later retry fails or is skipped.
Keep reporting honest
Missing evidence stays unknown rather than being presented as success. Delivery evidence describes the server request; it does not guarantee that Meta attributed the purchase to an ad. Marketing consent and missing connection settings can prevent a server event without blocking the order.
