The 24-hour customer service window
WhatsApp lets a business send free-form messages (text, media) only while a customer service window is open. The window opens when the contact writes to your number and closes 24 hours after their most recent message. Each new message from the contact restarts the 24 hours.
Outside the window, WhatsApp accepts only approved templates. Plexwire does not send the message and answers with this error instead.
What to do
- Send an approved template (
type: template). A template can start a conversation at any time. - Once the contact replies, the window opens again and you can send free-form messages.
- To avoid the error, check the time of the contact’s last inbound message before sending free-form content.
