What is the 24-Hour Messaging Window?

5 Min Read·Updated 2026·Meta Official API

To encourage businesses to respond to customers quickly, Meta has a rule called the 24-hour customer service window. Understanding this rule is essential for managing your conversations effectively.

What is the 24-Hour Window?

  • A 24-hour messaging window begins whenever a customer sends you a message.
  • Within this 24-hour period, you can reply to the customer with free-form messages (any type of content) without needing to use a pre-approved template.
  • Each time the customer replies to you, the 24-hour window resets from the time of their latest message.

What Happens When the Window Closes?

  • After 24 hours have passed since the customer's last message, the window closes.
  • You can no longer send free-form messages to that customer.
  • To re-initiate a conversation with a customer after the window has closed, you must use a pre-approved Message Template.

Practical Examples

Scenario 1: Inside the Window

  • 10:00 AM: Customer messages you: "Hi, what are your store hours?"
  • The 24-hour window opens.
  • 10:05 AM: You reply: "Hi! We're open from 9 AM to 6 PM." (This is a free-form message).
  • 2:00 PM: The customer replies: "Great, thanks!"
  • The 24-hour window resets and will now close at 2:00 PM the next day.
  • 4:00 PM: You can send another free-form message: "You're welcome! Is there anything else I can help you with today?"

Scenario 2: Outside the Window

  • Monday, 10:00 AM: Customer messages you. You have a conversation.
  • Monday, 2:00 PM: The customer sends their last message. The window will close on Tuesday at 2:00 PM.
  • Tuesday, 3:00 PM: The window is now closed. You try to send "Just following up!" but it will fail.
  • Solution: To contact the customer now, you must go to the Templates section of the chat composer in LeadClose and send an approved template, for example, a "Follow-up" template.
