});Utility Messages — FAQ
What qualifies as a utility message on WhatsApp?
Utility messages are transactional notifications directly related to an existing customer action or request. Examples include order confirmations, shipping updates, appointment reminders, payment receipts, account alerts, and booking confirmations. These messages must be sent using pre-approved templates.
How are utility message costs calculated?
WhatsApp charges for utility messages per 24-hour conversation window. Once a utility message is delivered, a 24-hour session starts, allowing you to send multiple updates in that category to the user without additional costs. Rates are determined by Meta based on the recipient's country code.
Can utility messages include file attachments?
Yes. You can attach PDFs (like invoices or receipts), images (like QR codes or tickets), and other document formats to your utility template messages. These files must be hosted online and passed as media parameters via our API or dashboard.
How long does template approval take for utility messages?
Utility template approvals are managed by Meta and are typically processed automatically within a few minutes. In rare cases, if manual review is triggered, it may take up to 24 hours. Once approved, the template is immediately available to use.
What is the difference between a utility and service message?
Utility messages are business-initiated notifications templates used for transactional updates. Service messages are user-initiated conversations, where a customer messages your business first, starting a 24-hour window where you can reply with free-form messages without templates.
