To create a new event you can navigate to Workspace>Events>Event Pages. Once there you can click on the "+New" menu and select Event Page.
The wizard will walk you thru all the steps to create your Event Page. Under the last step you will come to the Preview & Publish area and this creates your custom URL. We recommend copying and pasting this URL behind a button on your current website. There is also an embed code to use for your website if you prefer to embed the page within your website.
