Combined with the WhatsApp Pro version, you can install and activate WhatsApp addon for Dokan to get an extra module for vendor pages.
In order to make use of WhatsApp widget for Dokan vendors, make sure to have these plugins activated on your site:
Dokan: Lite version or Pro version
WhatsApp: Pro version
NinjaTeam WhatsApp addon for Dokan Vendors (free)
When NinjaTeam WhatsApp addon is active, it'll make some changes to your admin WhatsApp settings. Therefore, the WooCommerce Button settings will be set up in vendor view instead of admin view.
Please log in as a vendor using vendor username and password.
From Dokan vendor dashboard, go to Settings > WhatsApp to find the WhatsApp integration setup panel.
Here you can enter a WhatsApp phone number or group invite link.
This is the little text on the WhatsApp widget's label. It's also shown on the WooCommerce button on the vendor's single product pages.
Enabling this option makes a WhatsApp click to chat button show on all of the vendor's product pages.
Enabling this option makes the WhatsApp floating widget appear on the right corner of all pages associated with the vendor, including store page, collection page, product page, etc.
These options for each vendor's WhatsApp button/widget run independently of the others. So each vendor has his/her own support channel and is unaffected by admin settings.
