WhatsApp’s 24-Hour Reply Window: What Your Business Needs to Know

If a normal WhatsApp reply will not send, the customer’s reply window may have closed. That is one possible reason, so check the failed message before assuming there is a problem with your agent.

The rule affects Wabery’s hosted agent and team inbox as well as other tools using the WhatsApp Business Platform.

What opens the reply window?

A customer’s message opens a 24-hour window for normal replies. Each new message from that customer resets it. Your own replies do not extend the window.

Outside that window, business messages need an approved template. Sending a template does not itself reopen normal replies; a customer response does. Consent and content rules still apply within the window.

Help the customer while they are there

Use the conversation to give a useful answer and a clear next step. Someone asking about a service may need the price, a booking option, or help from your team.

Wabery combines a WhatsApp agent with leads, reservations, and a team inbox. You can set it up yourself using your business information. The agent can answer routine questions, gather confirmed enquiry details, and help customers book through Reservations.

Your team can take over when personal help is needed. Decide who will check handoffs so an enquiry does not wait unnoticed.

Plan later messages deliberately

An appointment update and a marketing offer are different jobs. Choose the appropriate approved template, get the required permission, and respect requests to stop.

Wabery supports WhatsApp templates. Check the setup needed for your intended follow-up; creating an agent does not automatically turn on every reminder or marketing campaign.

Does an open window mean free messages?

No. The reply window determines which type of message you can send. Delivery charges follow separate pricing rules.

Wabery’s plan, AI usage, and WhatsApp message fees are separate costs. Check current pricing rather than assuming an incoming enquiry makes every reply free.

What if your team also uses the phone app?

Eligible businesses can keep using the WhatsApp Business app while connecting Wabery. This has its own setup requirements. A message sent from the phone app does not extend the reply window for Wabery.

Test the complete journey

Try a routine question, an enquiry or booking request, and a handoff. Check what happens when the customer needs follow-up later.

You can test a Wabery draft privately before connecting your business number. Start with a useful customer journey and review the replies before publishing.
