Frequently Asked Questions
Can I put a chatbot on WhatsApp for free?
WhatsApp Business App (for single users/small businesses) is free and allows basic automated messages. For proper chatbot flows, broadcast messaging, and team inbox features, you need the WhatsApp Business API — which requires an approved provider (WATI, ManyChat, etc.) and costs from $15-49/month plus Meta's conversation fees.
How much does WhatsApp Business API cost?
The API itself is free through Meta-approved providers, but providers charge $15-79/month for their platform. Meta charges per conversation: marketing conversations cost ~$0.0248 (UK), service conversations are free for the first 1,000/month then ~$0.0045 each. Total costs depend heavily on conversation volume and type.
Is WATI the best WhatsApp business tool?
For dedicated WhatsApp Business API automation — yes. WATI's template management, broadcast campaigns, and customer service flows are purpose-built for WhatsApp. If you need multi-channel (WhatsApp + other platforms), Respond.io or ManyChat offer better unified inbox experiences.
