Common WhatsApp Business Errors

“Unapproved model”

The model used has not yet been validated by Meta, or has been rejected. Check its status in WhatsApp > Templates.

“Chat window expired”

You are trying to send a free message (non-templated) to a user who has not contacted you for more than 24 hours. Use an approved template to get the conversation going again.

“Number not registered on WhatsApp”

The recipient does not have an active WhatsApp account associated with this number. If SMS fallback is activated, the message will automatically switch to classic SMS.

“Daily messaging limit reached”

Meta imposes progressive (“third party”) volume tiers on new WhatsApp Business accounts, increasing automatically depending on the quality and regularity of your sendings. Contact support if you need an accelerated increase.
