FAQ

WhatsApp API Questions

Do I need Meta business verification?
Yes, WhatsApp Business Platform requires business verification through Meta. Our onboarding team guides you through this.
How long does template approval take?
Template review is handled by Meta and typically takes anywhere from a few hours to a couple of days.
Can I use the API alongside the Team Inbox?
Yes — the API and Team Inbox share the same number, so developers and agents can work side by side.
Is pricing separate from Meta's messaging charges?
Yes. WaSarthi's platform fee is separate from Meta's conversation-based messaging charges. See the pricing page for details.
