WhatsApp

Let's prepare your custom link for WhatsApp. It's simple. To create your own link, use https://wa.me/<number> where the <number> is a full phone number in international format.

Omit any zeroes, brackets or dashes when adding the phone number in international format.

By the way, you can also create your own link with a pre-filled message that will automatically appear in the text field of a chat, use https://wa.me/whatsappphonenumber/?text=urlencodedtext where whatsappphonenumber is a full phone number in international format and URL-encodedtext is the URL-encoded pre-filled message.

So you've created your own custom link with your phone number and may be, if you want, with a pre-filled message. Copy it to your buffer for the next steps.

The last step is very simple. Just add a new banner with the following details:
Header: "Chat with us in WhatsApp"
Caption (if needed): Any caption
Image: We advice you to upload logo of WhatsApp.
Link: That you've copied before.

That's it. Now those customers, who'd like to continue conversation with you in WhatsApp will be redirected to their account and linked directly with your WhatsApp account.
