I want to create an attribute on my directory listing WordPress site where visitors will enter their WhatsApp contact and when clicked upon will lead them directly to chat with listing authors on WhatsApp with their listings URL displaced so the author can know exactly which listing they are talking about.
For example, your site has 3 listings for suppose… If I click on the first one and then click on their WhatsApp number then it will redirect to WhatsApp with listing 1 URL included in the prewritten text
