# 10. How to use click to chat ?
WhatsTool Business's click to chat feature allows you to begin a chat with someone without having their phone number saved in your phone's address book. As long as you know this person’s phone number and they have an active WhatsApp account, you can create a link that will allow you to start a chat with them. By clicking the link, a chat with the person automatically opens.
### Create your own link
\
Use [`https://app.whatstool.business/:api_number/send?phone=`](https://app.whatstool.business/:api_number/send?phone=)``
where the `` is a full phone number in international format. Omit any zeroes, brackets, or dashes when adding the phone number in international format.
#### Examples
\
Use : [`https://app.whatstool.business/:api_number/send?phone=1XXXXXXXXXX`](https://app.whatstool.business/:api_number/send?phone=**1XXXXXXXXXX)
Don't use :
