What 131047 means
Meta's error text is "Re-engagement message": more than 24 hours have passed since the customer last replied. The window is counted from the customer's last message, not from yours.
- Inside the window: any text, image or document can be sent.
- Outside the window: only a template that Meta has approved can be sent. A free-form message fails with 131047.
The same workflow can work all morning and start failing in the afternoon, because each customer's window closes at a different time.
How to fix it
- Create a template in WhatsApp Manager, for example a short follow-up that asks the customer to reply. Approval usually takes minutes to a few hours.
- In n8n, Make or Zapier, send that template when the window is closed. The node or module has a separate option for template messages.
- When the customer replies, the window opens again for 24 hours and free-form messages work.
- Store the time of each customer's last message, so the workflow can choose between a template and a free-form message before it sends.
Avoid it in the first place
- Reply to new messages quickly, so most answers go out inside the window.
- Send reminders and follow-ups that happen days later as templates.
- Log failed sends with the customer's number and error code, so a 131047 is seen the same day instead of when the customer complains.

Questions people ask first
Does sending a template cost money?
Meta charges per template message by category and country. Replies inside the 24-hour window that the customer started are not charged as template messages.
Can I reopen the window myself?
Only by sending an approved template. The window reopens when the customer replies to it.
Is 131047 the same as being blocked?
No. It only means the window has closed. A customer who blocked the number gives a different result.
