Chrome and Edge integration
Blue Prism uses a native messaging host application to communicate with the browser extension. When a browser is launched from Blue Prism, a native messaging host application is started behind the scenes that listens for any incoming messages from Blue Prism and sends them to the browser extension.
The Blue Prism installer automatically installs the configuration settings for the native messaging host, regardless of whether the user selects to install any of the browser extensions or not. An additional registry key for the native messaging host is created and points to a JSON file which provides details on the allowed extensions and the location of the executable.
There are two Blue Prism browser extensions:
- Chrome – Used to automate applications and web pages in Google Chrome.
- Edge – Used to automate applications and web pages in Microsoft Edge.
Browser-based applications can also be automated natively via a Citrix virtual desktop environment in which Blue Prism has been installed with the browser extensions enabled.
