WhatsApp Business API Official Pricing Details (Hong Kong Region)
Important Notice: These charges are directly billed and settled by Meta (WhatsApp's parent company) based on usage. HelloClinic, as a technical service provider, does not make any adjustments or markups to these communication fees. We only assist you in connecting to and using this official service.
Pricing Model: Based on "Conversations"
WhatsApp Business API's pricing is not charged per individual message, but rather based on 24-hour conversation sessions. When you or a user initiates a conversation, all messages exchanged between both parties within the next 24 hours (regardless of quantity) will be counted as one billable conversation.
After 24 hours, if a business needs to send another message to the user, it will start a new billable conversation session.
Conversations are divided into four types, each with different pricing:
- User-Initiated (Service): When a user first messages your clinic to start a conversation. Commonly used for inquiries, appointments, and customer service.
- Business-Initiated: When your clinic proactively sends messages to users, starting a conversation. These are further categorized into three types based on content:
- Utility: Sending information about specific transactions or account-related updates that users have agreed to receive. Examples: appointment confirmations, follow-up reminders, receipt notifications.
- Authentication: Sending one-time passwords (OTP) to verify user identity. Example: login verification codes.
- Marketing: Sending promotional offers, product information, service updates, and other non-transaction related messages.
Monthly Free Conversation Allowance
Meta provides each WhatsApp Business Account (WABA) with:
- The first 1,000 "User-Initiated (Service)" conversations each month are completely free.
This means if your clinic primarily handles patient inquiries, the first 1,000 conversations will not incur any official Meta charges. Business-initiated conversations are not included in this free allowance.
