The Twitter extension allows you to push events to Twitter automatically from your calendar.
To post your event on Twitter, follow these steps:
Visit Twitter Apps and sign in with the account you wish to use for integration with your calendar. Click “Create a new application.”
Make sure “Enable Callback Locking” is disabled:
Once you have copied these values – click on “Follow this link to authorize this app to post to Twitter.”
Go into your WP Admin Dashboard > Events > Settings > Add-ons > Twitter and authorize your Twitter application.
Please note: it’s best to use the same Twitter account that you expect to be posting tweets. You may re-visit that link later to change the user.
To post your event to Twitter, go into the event edit page and click on “Post to Twitter”
