If you have a Facebook Page you can add a link to your WhatsApp channel by default.
To add this button you just need to edit your Page Information.
In the settings list there is a “WhatsApp option” to add your WhatsApp phone number and you can add a button with the link to your WhatsApp channel.
Is that easy and it is free.
