All platforms .. but that wasn't an option to choose
What exactly do you mean by adding Eventbrite to Todoist? What type of functionality did you have in mind?
I suppose it is more like can Todoist contact Eventbrite and other places
like that and interface them so that I can get eventbrite to
add an event to my todoist list. I use todoist as a calendar program and
other calendar programs can be automatically updated ..
This should be possible with out Zapier integration. At least, it's an option on their website. I just tested a setup of a new task when a new event is created, and it's possible.
