Is there a free WhatsApp Business API?
Yes — you can start for free. WhatsFlow B2B lets you launch the official WhatsApp Cloud API with no credit card and no setup fee. On top of that, Meta itself makes service replies free and utility free inside the service window, plus a free 72-hour window for people who reach you from a Click-to-WhatsApp ad.
You only pay Meta’s standard per-message fee for marketing and authentication — the same for any official provider. Everything else to run your WhatsApp (AI, team inbox, campaigns, bot) is included as you start, so you can go live today and scale later.
