What is the 24-hour customer service window?

The 24-hour customer service window is the period after a customer's most recent message during which a business can send free-form (non-template) messages of any kind. When the window closes, the business can only reach the customer with an approved message template until the customer writes again.

The 24-hour service window

Every customer message restarts the 24 hours from that moment.

Why it matters

The window is WhatsApp's core anti-spam rule: businesses can talk freely only while the customer is engaged. It shapes every workflow. Agents must answer within a day or switch to a template; automated replies must check the window before sending free text; a lead who goes quiet can only be re-engaged with a template and its cost.

In VGraple CRM

Each conversation header shows the time left in the window. When it closes, the composer offers approved templates instead of free text, flows switch to template steps automatically, and sequences schedule template steps for closed windows. Ad-originated chats show the extended 72-hour window.

Frequently asked questions

Can I send a free-form message after 24 hours?
No. Meta rejects it with error 131047. Send an approved template instead; if the customer replies, the window reopens.
Does the window apply to media and documents?
Yes. Any non-template message, including images and PDFs, requires an open window.
Does an agent's reply reset the window?
No. Only inbound messages from the customer reset the timer.
