How do I get an API Key?

API Key creation is automatic during plugin activation and setup. See our help documentation for an in-depth walk-through.

Are there any limitations to the free version?

No limitations! All the essential calendar features are available at no cost. No trials, no cedits, no limit on how many events you can create. A MegaCalendar Pro API key is only needed for the additional pro features outlined above.

Can I send and receive specific events with another website?

Yes, you can send events from one calendar to another, and auto-approve, or approve one by one. In order to receive events from someone else’s Calendar, you must have a MegaCalendar Pro API Key. See help documentation on our website

The setup is highly customizable so you can auto-send new events to a particular recipient (skipping any new event as needed), send events one by one, and even send recurring events if needed.

Can I have the same calendar on two websites?

Yes, you can use the same API Key on multiple websites to have identical events display on more than one WordPress website. See help documentation on our website

Can I customize the calendar or event lists?

MegaCalendar is designed to be easy to modify the look, feel and layout as needed. See our developer documentation for specific details on theme overrides, hooks, and more.

In addition you can use custom CSS, shortcode options, and multiple views and categories to present events however is best for your use-case and style needs.

Where are events saved?

Your event data is saved in in the cloud (in our case a protected AWS database). Event listings on your website are powered by the MegaCalendar API.

Remind me, what’s an API?

An elegant solution to share data from the cloud to one or more destinations. MegaCalendar was originally built for a school district that needed to share specific events between eight unique school websites and their main school district website.
