Sorry, I can’t quite understand the desired result, but the shortcode itself seems to be ok - it should display the value of the listing attribute passed to the “whatsapp” shortcode parameter. I recommend using this code snippet, though Attribute as shortcode - #13 by ihor Then you can use this shortcode within the listing page template, e.g. if you have a Messenger attribute (with the field name “messenger”), you can do this:
[hivepress_listing_attribute name="messenger"]
Hope this helps
