How long does WhatsApp Business API setup take?

5 to 10 working days end to end. FB Business Manager and number verification take 2-3 days. The first batch of template messages takes 1-2 days to get Meta approval. Multi-agent inbox and CRM integration adds another 3-5 days depending on which BSP.

What does WhatsApp Business API actually cost per month?

Two layers. Meta charges per conversation (a 24-hour window): roughly Rs. 0.78 per marketing conversation and Rs. 0.30 per utility conversation in India. Your BSP (Wati, AiSensy, Interakt, Gupshup, etc.) charges a platform fee on top, usually Rs. 1,000 to Rs. 10,000 a month plus a small markup per message. I help pick the BSP that fits your volume.

Will I get my number blocked for broadcasting?

Not if you do it the right way. The API tracks opt-in for every contact, uses pre-approved templates, and gives you a Meta quality rating (high/medium/low) you can monitor. Spam complaints drop the rating; bad quality drops your sending tier. Done correctly you can go from 1K daily to 100K+ daily within weeks.

Can I keep my existing phone number?

Yes, but you have to migrate. The number cannot be active on the regular WhatsApp Business app while it is on the API. The migration is one-time, takes about 30 minutes, and you lose the chat history from the app. New conversations on the API land in your multi-agent inbox.

Move off the free WA Business app before it gets you banned.

Your sales team is on three phones. Your last broadcast hit 200 contacts before the number went red. You want one inbox, opt-in tracking, and broadcasts that survive Meta's quality rating. The official WhatsApp Business API is the only way. I handle the BSP pick, the Meta verification, the template approvals, and the CRM wiring.

Every piece of the WhatsApp API stack, set up properly.

Most BSPs sell you a dashboard and disappear. I set up the account, write the templates, design the flows, and wire it to your CRM. Then I train your team.

Account + green tick

Facebook Business Manager, phone number setup, business verification, official business account application. Green-tick request submitted when you qualify (50K+ active users helps).

Template library

Multi-agent inbox

Assignment rules, shift handovers, response-time SLAs, canned replies, contact tagging. Your support team works inside one inbox, not three personal phones.

Chatbot + handoff

Bot handles FAQs, qualifies leads, and books slots. Smart handoff to a human when intent is unclear. No infinite "type 1 for X" loops that send customers to your competitor.

CRM and broadcast wiring

Two-way sync with HubSpot, Zoho, or your CRM. Broadcasts triggered from CRM segments. Opt-in tracked per contact with an audit log so you survive a Meta review.

[ 06 / FAQ ]

What founders actually ask before moving to the official API.

If you broadcast to more than 256 people, run support across more than one agent, or want to plug WhatsApp into your CRM, you need the official API. The WA Business app caps at one device and 256-contact broadcast lists, and aggressive sending gets the number banned within 24 hours. If you are a solo founder messaging 50 contacts a week, stay on the app.

5 to 10 working days end to end. FB Business Manager and number verification take 2-3 days. The first batch of template messages takes 1-2 days for Meta approval. Multi-agent inbox and CRM integration adds another 3-5 days depending on which BSP.

Two layers. Meta charges per conversation (a 24-hour window): roughly Rs. 0.78 per marketing conversation and Rs. 0.30 per utility conversation in India. Your BSP charges a platform fee on top, usually Rs. 1,000 to Rs. 10,000 a month plus a small per-message markup. At 10,000 marketing conversations a month total cost lands around Rs. 9,000 to Rs. 18,000.

Depends on your volume and use case. AiSensy and Wati for SMEs under 50K messages a month, friendlier dashboards. Interakt for D2C e-commerce because of Shopify integration. Gupshup and 360dialog for higher volumes with deeper API access. Zoko if you need fast WooCommerce setup. I write a one-page comparison for your specific case before recommending and have no kickback partnerships.

Not if you do it the right way. The API tracks opt-in for every contact, uses pre-approved templates, and gives you a Meta quality rating you can monitor. Spam complaints drop the rating, bad quality drops your sending tier. Done correctly you can go from 1K daily to 100K+ daily within weeks. Done badly the number goes red in 48 hours.

Yes, but you have to migrate. The number cannot be active on the regular WhatsApp Business app while it is on the API. Migration is one-time, takes about 30 minutes, and you lose the chat history from the app. New conversations on the API land in your multi-agent inbox.
