Frequently asked questions about WhatsApp Business API
- Have you built a multi-tenant WhatsApp SaaS?
- Yes — AI Walay is a multi-tenant SaaS where businesses connect their own WhatsApp Business API credentials and manage campaigns, contacts, and customer conversations.
- How do you handle Meta's template approval process?
- We design templates within Meta's policy (no promotional language outside Marketing category, proper variable syntax, language tagging) and submit through your BSP (typically WhatsApp Cloud API direct or Twilio).
- What's the conversation cost?
- Meta charges per 24-hour conversation window, varying by country. We model this in the pricing page so your team can predict monthly Meta spend before sending.
