Meta WhatsApp Error Code 131047 (WABA Re-engagement / Outside 24h Window) — Customer Service Window Closed — Fix

Overview

Error code #131047 — "Re-engagement Message (Outside 24h Window)". The 24-hour customer service window has closed, so you can't send a free-form message. This is expected WhatsApp behaviour, not a bug.

Why This Happens

• More than 24 hours have passed since the recipient last sent you a message. Outside that window, only approved template messages are allowed.

How to Fix

1. Send an approved template message to reopen the 24-hour window.
2. Once the customer replies, the window reopens and you can send free-form messages again.
