I did find it rather tricky getting the calendar to connect with the EventBrite. After installing the Events Calendar plugin, I did get the new features showing in the New Post dialog: Is this an Event? (O)Yes (O)No – and then I created an event.
Then I installed the Eventbrite plugin, and went back to the post, and there was a choice to ‘push’ the event to Eventbrite, which I did, but it still didn’t seem to work. I poked around a bit until I found I needed to (CRITICAL STEP) get my API code from Eventbrite and insert it in the bottom of my admin user profile. Then things seemed to be hooked up, and I created a ticket in Events Calendar. (PS: I can create Eventbrite tickets ONLY from the admin user acount, because it is associated with the API. If I try to create an event from my “Editor” user account, it does not work.)
I went to EventBrite.com and found that the event was not there, saying “no tickets have been set up” even though I had set one up in WordPress. I went ahead and created the identical ticket at Eventbrite.com, and bingo, it shows up in the post view.
Convoluted, I know. I have had to repeat this roundabout for the second event, but ultimately it sells tickets directly out of WordPress as advertised.
