GCal Events List retrieves events from Google Calendar and shows data in a widget.
To make GCal Events List work properly, you have to activate the plugin and paste your Google Calendar API key and a public calendar ID in the widget admin panel.
It requires some other options. Here is the full list of params:
<ol>
<li>Title (widget title)</li>
<li>Calendar ID (you can find it in the option panel of your Google Calendar)</li>
<li>Google API key</li>
<li>Start from (a valid date in YYYY-MM-DD format)</li>
<li>Max results</li>
</ol>
For a detailed description of calendar settings, read the <a href="https://developers.google.com/google-apps/calendar/" rel="nofollow ugc">Google Calendar Data API documentation</a>
REMEMBER: your Google Calendar must be public, otherwise the widget won’t show any event!
