In this section, we are highlighting the most important parts of WhatsApp Business Policy. Any business using WhatsApp API via Amio must read the whole version.

24-hour Customer Service Window

An excerpt from WhatsApp Business Policy:

If a person initiates a chat with you, you may continue that conversation via WhatsApp for up to **24 hours** after the last message sent to you by that person without charge (“Customer Service Window”). Outside of the Customer Service Window, you may only send messages via approved Message Templates, for which we will charge the applicable rate.


An excerpt from WhatsApp Business Policy:

In order to send a WhatsApp message to a person, you must receive opt-in permission in-line and contextually during the relevant user flows. For example, to receive a receipt via WhatsApp, a person must opt in during a purchase flow. Opt-in obtained without context and in any manner not related to an action the user is already taking, does not comply with this policy.

You can find out a more in-depth description of opt-ins here.
