A click-to-WhatsApp (CTWA) ad only opens the chat; value is what answers in the first seconds. The serious stack is: ads → Cloud API number → qualifying agent prompt → human handoff in inbox → templates only when you leave the 24-hour window. With coexistence, the team stays on app/Web. 42agents provides the white-label agent + inbox; Meta bills conversations by category.
Designing the first message
The agent should: greet with ad context, ask 2–3 qualifying questions, offer value (price/booking/catalog), and offer a human. Do not dump the whole catalog or ask for ID in message one.
Use the site’s sales prompt templates as a base and adapt vertical + offer.
Frictionless handoff
Define triggers: “talk to an advisor,” complex price objection, complaint, after-hours with booking. The multi-user inbox (3 included per account on 42agents) needs clear thread ownership rules.
Measure time to first human reply when the agent escalates; if it takes 40 minutes, CTWA feels broken even with cheap CPC.
Costs and number quality
CTWA can open marketing conversations or land in service depending on the flow. Model Meta cost with the calculator before scaling budget. Watch quality rating: irrelevant replies or template spam kill the number.
Generate backup wa.me / QR with site tools for landings that are not ads-only.
