We recently published a new API for the Calendar that enables you to display a mini calendar grid anywhere on your website. We already have an API to display upcoming events but there wasn't any way to display those events in a calendar grid format.
The new API call will display the current month and you can have links to the days of the month that have events. Pretty much anything that you can already do with the mini-grid on regular Calendar app pages you can do with this API.
Below is a sample API call to display the mini-grid. It supports most of the same parameters that the eventFilter API call supports.
