Do test events affect reporting?
No. Use Meta's test event code to keep the payload out of production reports while you debug.
Browser-side tracking alone is no longer enough. Facebook expects advertisers to send server-side events through the Conversion API, and the quality of those payloads influences attribution, bidding, and compliance.
Use it when onboarding new offers, changing pixels, or debugging hashed identifiers. The response exposes warning messages about missing parameters, hashing mismatches, or rate limits so you can fix issues before the next optimization cycle.
