What WhatsApp messaging restrictions apply?
WhatsApp freeform messages are limited to the customer care window; outside it you need approved Message Templates. Meta bills WABA fees.
WhatsApp messaging follows Meta’s rules. CommentLink surfaces those limits in Live Inbox and channel status — it cannot bypass them.
Customer care window
After a person messages you, you typically have a limited window (commonly 24 hours) to send freeform WhatsApp replies. Outside that window, freeform sends fail.
Approved Message Templates
Outside the window, use Meta-approved WhatsApp Message Templates. These are unrelated to Instagram Automation Templates in Templates.
Connection readiness
In Channels, WhatsApp should be connected with successful registration / webhook subscribe status for reliable delivery.
Costs
Meta conversation fees are billed to your WhatsApp Business Account (WABA). CommentLink does not replace Meta’s billing for those conversations.
