A widget is a portable chunk of code that can be installed and executed within the designated sections of ActiveCampaign products. Products that currently support widgets are Help Desk Software and Knowledge Management Software.
Widgets are mini-applications written in PHP that should be placed within the application installation folder in order to be accessible by the system. Once installed, a widget can be added to designated widget bars of that application on Widgets page, usually located under Administration or Settings menu.
Anyone with a knowledge of PHP programming can write their own widgets for ActiveCampaign software products. Some widgets (such as Custom HTML and RSS Feed widgets, among others) can be used in any product, while some might be tied to the application they are meant to be used in, and therefore are not usable for other ActiveCampaign products. If you attempt to add a widget for an application that doesn't support that type of widgets, the widget will simply not appear in the "Available Widgets" list.
