Understanding WhatsApp's 24-Hour Messaging Window
Everything you need to know about WhatsApp's messaging rules and how to work within the 24-hour window.
The 24-hour messaging window is one of the most important concepts to understand when using WhatsApp Business API. It determines when you can send free-form messages to customers.
What is the 24-Hour Window?
When a customer messages you, a 24-hour window opens. During this time, you can send any type of message - text, images, documents, or videos - without using an approved template.
What Happens After 24 Hours?
Once the window closes, you can only send approved message templates. This is why templates are crucial for re-engaging customers.
Re-Opening the Window
The window resets each time a customer sends you a message. Providing value and encouraging responses keeps the window open.
Best Practices
Respond Quickly
Don't waste the 24-hour window. Respond to customer inquiries promptly.
Encourage Engagement
Ask questions, provide helpful information, and make it easy for customers to respond.
Use Templates Strategically
Send template messages to re-engage customers and open new conversation windows.
Exceptions to the Rule
Service conversations initiated by customers always open a window. Authentication messages can be sent without a prior window.
