Error when sending GET request to Eventbrite: Unknown parameters

Hey folks, I’m a bit of a Zapier newbie - I’d love some help setting up this Zap. Basically it takes an Eventbrite event id, asks Eventbrite for data about that event, and parses it. It seems to work when I’m creating the Zap/testing it, but when I actually run it I get an error about unknown parameters. 

The eventbrite article I’m following is here:, and I’ve screenshotted the relevant part of my Zap below:




Any help appreciated!

Hi @oliphant 

See the description underneath the URL Field.

Essentially anything after the ? is a query string parameter.

Try moving “expand” to the left side of the Query String Params section, and “ticket_classes” to the right side.


That worked! Thank you so much 🙏🏻
