What Is the WhatsApp Business 24-Hour Window Rule, and What Happens If It's Broken?
If the team tries to send a regular message to a customer outside the 24-hour window, the message won't go through — in that case, a template approved by Meta is needed to reopen the conversation.
What the 24-hour window is
The official WhatsApp Business API, used by Jestor, works on a 24-hour rule: while the customer is active in the conversation, the team can reply freely. Once the customer stops responding for more than 24 hours, the window closes.
This rule exists to prevent spam and protect the end user's experience on WhatsApp, and it's set by Meta itself, not by Jestor.
What happens when the window is closed
- Free-text messages are not delivered to the customer
- A previously approved template must be sent instead
- If the customer replies to the template, the window reopens for another 24 hours
- While the window is closed, Jestor already flags this visually in the chat
How Jestor helps handle this rule
In the conversation panel, Jestor shows when the window is closed and already suggests sending a compatible template right from the message screen, without needing to leave the system to check the status.
WhatsApp automation with AI agents in Jestor
Besides flagging the closed window, Jestor lets you automate template sends by phase-change trigger or by button, and count on a native AI agent that already replies to the customer and keeps the team updated in real time on how the conversation is going.
Table Summary
| Situation | What happens | What to do |
|---|---|---|
| Window open (customer replied under 24h ago) | Free-text messages are delivered normally | No extra action needed |
| Window closed (more than 24h without a reply) | Free-text messages aren't delivered | Send a template approved by Meta |
| Customer replies to the template | Window reopens for another 24h | Team can chat freely again |
