This code example is a simple custom Search extension calling a REST API (you will have to either use your own search or apply for a free test API Key from the provider in the demonstration Search) and a custom CSS Progress Bar in the commit key to demonstrate how to inform the user of any post-processing that may be required. The example uses a free API and the URL to open a free account for testing purposes is included in the Zip Archive.

The article that accompanies this custom search extension can be read by following this link. A video is provided to demonstrate both the expected end result and the structure of the extension code. The Zip Archive contains the example shown and includes the CSS and JS files.
