This package makes working with a Google Calendar a breeze. Manage events on a Google Calendar. The first thing you’ll need to do is get credentials to use Google's API. I’m assuming that you’ve already created a Google account and are signed in. Head over to Google API console and click "Select a project" in the header. You can give the service account a name. You can name it anything you’d like. In the service account id you’ll see an email address. We’ll use this email address later on in this guide. Select "JSON" as the key type and click "Create" to download the JSON file. You will get a warning that the service account does not have a role, you can safely ignore this and create the service account without assigning a role. Head over to Google Calendar and view the settings of the calendar you want to work with via PHP. On the "Share with specific people" tab press the "Add people" button and add the service account id that was displayed when creating credentials on the API site.

Want to create online calendars so that you can display them on an iPhone's calendar app or in Google Calendar? This can be done by generating calendars in the iCalendar format (RFC 5545), a textual format that can be loaded by different applications. The format of such calendars is defined in RFC 5545, which is not a pleasant reading experience. This package implements RFC 5545 and some extensions from RFC 7986 to provide you an easy-to-use API for creating calendars. It's not our intention to implement these RFC's entirely but to provide a straightforward API that's easy to use.
