LiveChat widget

The LiveChat widget plugin integrates the LiveChat messaging feature into webpages. This widget facilitates real-time chat between the website visitors and the support or sales teams.




This plugin is used to inject the LiveChat widget, a popular customer support chat tool, into a webpage. The widget allows website visitors to communicate directly with customer support or sales teams. It requires a LiveChat license number for activation. Once configured, the plugin appends a JavaScript snippet to the webpage, activating the LiveChat widget. This enhancement can significantly improve user engagement and customer support efficiency.

Inputs and Outputs

  • Inputs: The plugin accepts a payload, typically containing the data necessary for the widget's operation.
  • Outputs:
    • response: Outputs the payload back after processing. The main function of this plugin is to append the LiveChat widget to the page, not to alter the payload.
    • error: Outputs in case of any execution error.


  • License: Your LiveChat license number, a crucial element for enabling the widget on your webpage.

Event prerequisites

Plugins like the Livechat widget, which fall under the "UIX Widgets" category, require a synchronous event. It will not work if sent event is asynchronous.


  • "License can not be empty.": This error occurs when the LiveChat license number is not provided in the plugin configuration. The license number is essential for the widget's operation.
  • General script-related errors might occur, usually related to the execution of the appended JavaScript in the webpage environment. These errors could arise from conflicts with other scripts or issues in the webpage's structure.
