Conversation Based Pricing Explained
Understanding how WhatsApp charges for conversations is essential for managing your messaging costs effectively.
How Pricing Works
WhatsApp Business API uses a conversation-based pricing model, not per-message pricing:
1 Conversation = Unlimited messages within a 24-hour window
Once a conversation starts, you can send as many messages as needed within that 24-hour session for a single conversation fee.
Conversation Categories
Conversations are categorized based on the template or message type:
📣 Marketing
Promotions, offers, product launches, newsletters
Used for promotional content like discounts, new product announcements, or marketing campaigns.
🔧 Utility
Order updates, reminders, confirmations
Transactional messages like order confirmations, shipping updates, appointment reminders.
🔐 Authentication
OTPs, verification codes, login alerts
Security-related messages like one-time passwords and account verification codes.
💬 Service
User-initiated conversations, customer support
When a user messages you first, it opens a service conversation where you can reply freely.
Sample Rates (India)
| Category | Rate (INR) |
|---|---|

Frequently Asked Questions
Are all WhatsApp messages charged the same rate?

What does a 24-hour conversation window mean?
A 24-hour conversation window means that once a conversation is opened (either by the business sending a template or a user messaging the business), you can send an unlimited number of messages of that category within the next 24 hours for a single flat fee.
How can I reduce my WhatsApp Business API costs?
You can reduce costs by using the cheaper Utility templates instead of Marketing ones when appropriate, encouraging users to initiate chats (which are free), and consolidating your messages within the open 24-hour window.
