Free entry point conversation

A WhatsApp conversation started when a customer taps a click-to-WhatsApp ad or a Facebook Page call-to-action. Meta gives these an extended free window to encourage ad-driven chat.

One term from the WhatsApp Business Platform glossary. Last updated 2026-07-25.

When someone arrives from a click-to-WhatsApp ad or a Facebook Page CTA, Meta opens a longer free window than the standard 24-hour service window. The business can converse without per-message template charges for that period.

This is a direct subsidy of ad-driven conversation, and it is a large part of why click-to-WhatsApp campaigns perform economically for lead generation: the qualifying conversation after the click costs nothing in messaging fees.
