What is the Meta Conversions API for WhatsApp?

The Meta Conversions API (CAPI) is a server-side interface for sending conversion events (lead, purchase, booking) from a business's systems to Meta, matched to the ad click that caused them. For WhatsApp, the click ID from ad referral data is attached to the event, so a purchase recorded in the CRM after a WhatsApp conversation shows up in Ads Manager against the ad that started it.

Why it matters

Meta's ad delivery optimises toward the events it can see. Without CAPI, a CTWA campaign is optimised for conversations, which rewards ads that start chats with tyre-kickers; with purchase events, it learns to find buyers. It also makes ROAS reporting honest for WhatsApp-led sales.
