# Sending WHATSAPP

{% hint style="warning" %}
To have an opportunity to send WHATSAPP messages, please contact your manager.
{% endhint %}

{% hint style="info" %}
Messages are sent in chat mode:

* if the chat is initiated by a client, the first message must match the registered template. Each time the subscriber replies, a 24-hour window will open to send messages with arbitrary content. If the subscriber does not reply, the client can send messages to the user outside the 24-hour window using pre-registered message templates;
* if the chat is initiated by the subscriber, during the 24-hour window the client can send messages with arbitrary content.
