Direct, factual answers to the most important questions about WhatsApp Business API pricing, compliance, bulk broadcasts, and team collaboration in India.
Direct Answer: What is the most important thing to know about WhatsApp API?
The most important distinction is that WhatsApp Business API is an official, ban-free enterprise cloud infrastructure that separates software platform tools from Meta conversation fees. It allows businesses to send broadcast campaigns to tens of thousands of contacts, collaborate in a shared multi-agent inbox, and automate workflows with 100% legal compliance in India.

General & Fundamentals
Is the WhatsApp Business API free?
No. Unlike the consumer WhatsApp Business App, the API involves official Meta conversation fees (Marketing ~₹0.86, Utility ~₹0.115 in India) and a software platform subscription. However, Meta provides 1,000 free customer service conversations every month to every business account.
Can I use WhatsApp Business API without coding?
Yes. Wapi provides a complete, visual web interface. You can connect your number in 15 minutes using Meta Embedded Signup, upload contact lists via CSV, compose approved message templates, and chat in a shared inbox with zero coding required.
Can I use my existing WhatsApp phone number?
Yes. You can use any mobile, landline, or 1800 toll-free number. If the number is currently registered on the regular WhatsApp or WhatsApp Business App, you must first delete that consumer account to migrate it to the official Meta Cloud API.
What is the difference between WhatsApp Business App and API?
The WhatsApp Business App is a free mobile tool for sole proprietors limited to 4 linked devices and manual typing. The WhatsApp Business API is a scalable cloud infrastructure supporting unlimited agents, bulk broadcasts, automated chatbots, CRM integrations, and zero ban risk.
Is WhatsApp Business API legal in India?
Yes, 100%. It is Meta's officially authorized business messaging solution in India and is fully compliant with the Indian IT Act and TRAI messaging standards.
Pricing & Billing
How does Wapi's 'Zero Markup' model work?
Most legacy providers add a 15 to 25 paise surcharge on top of Meta's rates. Wapi charges ₹0 markup. Meta bills your conversation costs directly to your attached credit/debit card at wholesale rates, while you pay Wapi an unbeatable flat ₹999/mo subscription for unlimited platform access.
Can I claim GST Input Tax Credit on WhatsApp messaging charges?
Yes. When you enter your Indian company GSTIN in Meta Business Manager, Meta issues an official tax invoice with 18% GST, enabling your business to claim 100% Input Tax Credit (ITC).
What are the 4 WhatsApp message categories?
1) Marketing (~₹0.86 in India): promotional offers and sales; 2) Utility (~₹0.115): transactional order and shipping alerts; 3) Authentication (~₹0.115): OTP codes; 4) Service (1,000 free/mo, then ~₹0.38): customer-initiated support within 24 hours.
Broadcasts & Compliance
Will my phone number get banned for sending bulk broadcasts?
Not on the official WhatsApp Business API. As long as you use Meta-approved templates and honor opt-out requests (STOP/UNSUBSCRIBE), your number will never be banned. Unofficial bulk-sender Chrome extensions, by contrast, result in immediate bans.
Do recipients have to save my business phone number to receive messages?
No. API broadcasts deliver directly to the customer's lock screen regardless of whether they have saved your business phone number in their address book.
How does WhatsApp opt-in and opt-out work?
Businesses must obtain prior opt-in consent (via website checkout, SMS, or forms). Wapi automatically detects standard opt-out keywords (STOP, CANCEL, UNSUBSCRIBE) from inbound messages and instantly flags the contact as 'opted_out' to exclude them from future broadcasts.
What are WhatsApp daily messaging tiers?
Meta assigns a daily sending limit: Tier 250, Tier 1,000, Tier 10,000, Tier 100,000, and Unlimited unique contacts per 24 hours. Your tier automatically upgrades as you maintain a High/Green quality rating and consistently reach your limit.
Team Collaboration & Features
How many agents can use the Wapi shared inbox simultaneously?
Unlimited. Wapi does not charge per-seat fees. Your entire customer support and sales team can log in simultaneously from their web browsers to manage conversations on a single business number.
What happens when the 24-hour service window closes?
Meta locks free-form replies after 24 hours of customer inactivity. Inside Wapi's inbox, an agent can send an approved Template message (such as an appointment or order update) to re-open the window upon customer reply.
Can I receive audio voice notes and images in Wapi?
Yes. Wapi's inbox natively streams inbound audio voice notes with playback controls, previews high-resolution images, and displays PDF document attachments.
