Why it occurs
This error typically happens when the recipient does not receive or acknowledge the message within the configured validity period. Common reasons include the user being offline, having WhatsApp closed for an extended time, or connectivity issues.
Steps to resolve the issue
1. Check validity period settings
– Review the validity period defined for the message in your request.
– Increase the duration if needed to allow more time for delivery.
2. Consider recipient activity
– Confirm that the recipient is actively using WhatsApp and has a stable internet connection.
– Inactivity or prolonged disconnection may prevent timely message delivery.
3. Resend the message
– If the message was canceled, try resending it with an extended validity period.
– Monitor for delivery acknowledgment after resending.
4. Optimize message timing
– Schedule messages at times when recipients are most likely to be online.
– This increases the chance of timely delivery and acknowledgment.
