First decide: official or unofficial
Official providers (Wati, Interakt, AiSensy, Gupshup and others) use Meta's WhatsApp Business Platform. Your number is very unlikely to be banned, but every business-initiated message costs money and needs an approved template. Unofficial providers (AgaKural, Whapi, Green API, UltraMsg) link your existing number like WhatsApp Web. They are cheaper and more flexible, but the number can be restricted by WhatsApp. Our official vs unofficial guide goes deeper.
