Require phone number
olark.configure('system.ask_for_phone', 'hidden' );
Require visitors fill out their phone number in the pre-chat survey before chatting. This requires the pre-chat survey to be enabled first.
This setting can also be enabled on the pre-chat survey section of the Text & Forms settings page.
You can read more about using the pre-chat survey in our Help Center.
Even if the pre-chat survey is enabled in your settings, you would need to enable the plugin using this line to use the
system.ask_for_phone API call:
