Fix WhatsApp 24-Hour Window Error in Sparkforge

This error fires when you try to send a regular WhatsApp message to a customer more than 24 hours after their last reply. WhatsApp enforces the rule to keep its platform free of unsolicited outreach.

How the 24-Hour Window Works

• The window starts when the customer messages you.
• Inside the window, you can send free-form replies normally.
• After 24 hours of no inbound activity, the window closes.

Once closed, free-form messages will be rejected.

Why You Are Seeing This Error

Two conditions are true at once:

• The customer hasn't replied in over 24 hours.
• You're sending a regular message instead of an approved template.

How to Resolve It

1. Send a Pre-Approved Template Message

Use a WhatsApp template approved by Meta to reopen the window. Common template types:

• Appointment reminders
• Order updates
• Follow-up prompts

Once the customer replies to the template, the 24-hour window reopens and free-form messaging resumes.

2. Reach Out Through Another Channel

Email or SMS the customer asking them to reply on WhatsApp. Their reply restarts the 24-hour window.

Best Practices

• Reply inside the 24-hour window whenever possible.
• Use Sparkforge automations and workflows so responses don't slip past the deadline.
• Keep a library of approved templates ready for re-engagement.

What You Cannot Do

You cannot bypass the 24-hour rule. Resending a free-form message will keep failing. This is WhatsApp policy, not a Sparkforge limit.
