Which one does your business need?

Use WhatsApp Business App if:

You are a sole proprietor or 1–2 person business. You send fewer than 200 messages per month manually. You don't need automation, CRM integration, or bulk messaging. You're just starting and want to test WhatsApp before investing.

Use WhatsApp Business API if:

You have 2+ people who need to handle WhatsApp. You want automated order confirmations, reminders, or follow-ups. You run a Shopify/WooCommerce store and want cart recovery and tracking notifications. You want to send broadcasts to more than 256 contacts. You want to connect WhatsApp to your CRM (HubSpot, Zoho, Salesforce).

Rule of thumb for Indian businesses: If WhatsApp is a serious sales or support channel for your business (more than 10 conversations per day), the API will pay for itself within the first month through automation alone. The ₹2,499/month platform fee is a rounding error compared to the staff time saved.

WhatsApp API vs App questions

Can I use the App and API on the same number?
No — a number can only be registered on one product. To move from App to API, delete the App account first (15-day waiting period), then register on API via WA.Expert.
Is the API more expensive than the App?
WhatsApp Business App is free. The API requires ₹2,499/month (WA.Expert) plus Meta fees (₹0.35–0.82 per conversation). For automation-driven businesses, ROI typically exceeds cost within the first month.
Which businesses should use the API?
Any business with 2+ agents, more than 200 messages/month, automation needs, CRM integration requirements, or bulk broadcast needs. In practice, any growing business with WhatsApp as a core channel should move to API within 6–12 months.
Can I send bulk messages with the Business App?
App broadcasts are limited to 256 contacts and only reach people who saved your number. API broadcasts reach unlimited opted-in contacts with tracking and scheduling — significantly more powerful.
How long to migrate from App to API?
Minimum 15 days — the waiting period after deleting the App account. Plan during a low-traffic period. Chat history from the App is not transferred to the API.
How many users can use the App simultaneously?
1 primary device plus up to 4 linked devices. For teams larger than 2–3 people, the API with a multi-agent inbox is significantly better.
What about WhatsApp Business Premium?
WhatsApp Business Premium is an enhanced version of the Business App with up to 10 linked devices. It fills the gap between the App (5 devices) and full API. Suitable for teams of 5–10 who don't need full automation or CRM integration. Available in India as part of Meta's rolling rollout.

Ready to upgrade from App to API?

WA.Expert handles the migration, setup, and first automation. Most businesses are live within 3–5 business days.
