WhatsApp Business API Pricing 2026: Are Service Messages Also Chargeable?
By Chatkar Team | Updated September 27, 2026 | 6 min read
WhatsApp Business API helps businesses automate customer support, send notifications, manage enquiries and build chatbots. Understanding Meta's messaging charges is essential for managing monthly communication costs.
From October 1, 2026, the reported pricing structure provides for the first 1,000 eligible delivered service messages per business phone number per calendar month to be free. Additional eligible service messages may be chargeable.
1. What Is a WhatsApp Service Message?
A service message is a free-form reply sent by a business in response to a customer's WhatsApp message, subject to WhatsApp's messaging rules.
- Answering an order enquiry.
- Providing requested product information.
- Responding to payment-status questions.
- Helping customers through support conversations.
- Answering questions through a chatbot.
When a customer messages a business, a 24-hour customer service window opens. During this window, businesses can generally send free-form replies without an approved template, subject to Meta's applicable policies and pricing rules.
2. What Changes from October 1, 2026?
Before October 1, 2026
Eligible free-form service replies within the 24-hour customer service window are generally free of Meta messaging charges under the applicable rules.
From October 1, 2026
According to the reported pricing structure, each eligible business phone number receives 1,000 free service messages per calendar month. Additional eligible delivered service messages may be charged at the applicable rate.
The 24-hour customer service window and the monthly allowance are different. The window determines when free-form replies can be sent without an approved template; the allowance determines how eligible service messages are counted for billing under the reported structure.
3. What Does 1,000 Free Messages per Phone Number Mean?
The reported allowance is per eligible business WhatsApp API phone number, not separately for each customer, agent or chatbot.
| Business API phone numbers | Monthly free service messages |
|---|---|
| 1 number | 1,000 |
| 2 numbers | 2,000 |
| 3 numbers | 3,000 |
| 5 numbers | 5,000 |
Unused allowance should not be assumed to roll over into the next month. Verify the current eligibility rules before relying on these figures.
4. WhatsApp Service Message Cost Calculation: Ram and Shyam Example
Suppose Ram and Shyam contact the same business through one WhatsApp API number.
- Messages delivered for Ram: 1,001
- Messages delivered for Shyam: 500
- Total eligible service messages: 1,501
- Monthly free allowance: 1,000
- Chargeable messages: 501
Using an illustrative rate of ₹0.115 per additional eligible service message:
Estimated Meta charge = 501 × ₹0.115 = ₹57.62
This calculation is before GST and any additional platform or provider fees.
Important: Ram and Shyam do not receive separate allowances of 1,000 messages each. Their eligible service messages share the allowance of the business phone number used to send the replies.
5. WhatsApp Business API Pricing in India
The following are indicative rates reported for Indian recipient numbers, effective October 1, 2026. Verify the applicable rates against Meta's official rate card before budgeting or invoicing.
| Message category | Indicative rate | Pricing notes |
|---|---|---|
| Service message | ₹0.115 | First 1,000 eligible messages free per number/month under the reported structure; charges thereafter |
| Utility template | ₹0.115 | Applicable template pricing rules apply |
| Authentication / OTP | ₹0.115 | Applicable authentication pricing rules apply |
| Marketing template | ₹0.8631 | Applicable marketing pricing rules apply |
These are indicative Meta messaging rates, not a guarantee of a provider's total price. Rates may change and can depend on the recipient market, message category and applicable rules. GST and additional platform or provider fees may apply.
Service replies and utility templates are different categories. The reported service-message allowance does not make utility templates free.
For current pricing, consult the official Meta WhatsApp Business Platform pricing documentation.
6. Does This Change Affect WhatsApp Chatbots and Automation?
Businesses using WhatsApp automation should review their message volumes and billing reports. Examples include:
- Automated customer support replies.
- Chatbot responses to incoming enquiries.
- AI-powered customer support agents.
- CRM-triggered replies to customer questions.
- Human-agent responses through a shared team inbox.
Businesses using Chatkar or another WhatsApp automation platform should track eligible delivered service messages by connected business phone number. Not every automated message is a service message. Marketing, utility and authentication templates must be classified under their applicable rules.
7. How Can Businesses Manage WhatsApp Messaging Costs?
1. Track messages by phone number
Maintain a separate monthly usage count for every connected WhatsApp API number.
2. Reduce unnecessary chatbot replies
Use clear responses and avoid sending multiple messages when one concise answer can resolve the customer's question.
3. Classify messages correctly
Separate service replies, utility templates, authentication messages and marketing messages in reporting.
4. Set usage alerts
Where supported, configure alerts when a number reaches 70%, 90% and 100% of its applicable monthly free allowance.
5. Forecast monthly costs
Estimate the eligible messages expected to exceed the allowance and multiply that volume by the applicable rate.
6. Reconcile Meta billing
Compare platform message reports with WhatsApp Manager billing records and provider invoices to identify discrepancies.
8. Frequently Asked Questions
Are WhatsApp service messages free?
Eligible free-form replies within the 24-hour customer service window are generally free of Meta messaging charges under the applicable rules. Under the reported structure from October 1, 2026, the first 1,000 eligible delivered service messages per business phone number per month are free, with applicable charges thereafter. Verify the current rules before relying on these figures.
Is the 1,000-message allowance per customer?
No. Under the reported structure, the allowance is per eligible business API phone number per calendar month, not per customer, contact, agent or chatbot.
If 1,000 customers each receive one reply, is that free?
If all 1,000 replies qualify as eligible service messages, are delivered from the same business number, and none of the allowance has already been used, they fit within the reported monthly allowance.
Do incoming customer messages consume the allowance?
The allowance described here applies to eligible service messages delivered by the business, not messages sent by customers. Incoming messages may open the 24-hour customer service window.
Does a second WhatsApp API number get another allowance?
Under the reported pricing structure, each eligible business phone number has its own monthly allowance. Verify Meta's current eligibility requirements before calculating costs.
Are marketing messages included in the free allowance?
No. Marketing templates are billed under their applicable pricing rules and should not be assumed to use the free service-message allowance.
Will Chatkar charge extra?
Meta's messaging charges and Chatkar's subscription or service fees are separate. Any additional Chatkar fee depends on the applicable Chatkar plan and pricing terms.
Are Meta messaging charges the total WhatsApp API cost?
No. Total costs may include Meta messaging charges, a platform subscription, provider fees, optional services and applicable taxes. Check your provider's plan and invoice for the complete cost.
Conclusion
WhatsApp Business API remains useful for customer support, notifications and automation. Businesses should understand the difference between the 24-hour customer service window, eligible delivered service messages and template-message categories.
Under the reported pricing structure effective October 1, 2026, the first 1,000 eligible service messages per business phone number per month are free, followed by applicable charges. Confirm the effective date, rate card and eligibility rules through Meta's official documentation before making financial decisions.
Tracking usage by phone number, classifying messages correctly and reconciling billing records can help businesses manage WhatsApp communication costs.
