Error code 131047 usually occurs when you attempt to send a regular message to a recipient after 24 hours have passed since their last reply and you get the following error message, “More than 24 hours have passed since the recipient last replied to the sender number.” WhatsApp enforces the 24-hour customer service window, and messages sent outside this window require a pre-approved message template.

Here’s how to fix this issue and successfully re-engage your customers.

What Causes Error 131047?

This error happens when:

  1. More than 24 hours have passed since the recipient last responded to your WhatsApp Business number. Error 131047 is a reminder of WhatsApp's 24-hour customer service window policy. Whenever a customer sends you a message, a 24-hour window opens. During this time, you can send free-form messages back and forth with the customer without needing to use pre-approved templates. The window refreshes every time the customer sends a new message. Once the window closes, you will need to use a template to reach out to the customer again.

  2. The sender's WhatsApp number or other parameters are not properly updated.

How to Fix Error 131047

1. Use a Pre-Approved Message Template

To re-engage the customer, send a business-initiated message using a WhatsApp-approved message template.

  • Go to your WhatsApp Business Manager and choose an appropriate message template.

  • Use the WhatsApp API to send the message.


2. Verify Your WhatsApp Number and Parameters

If you try replying to a user-initiated message within the 24-hour window and still get this error then check that your WhatsApp Business number is correctly registered and ensure all parameters are accurate.
