1099-K from HS Reunion

Hello! I planned and was in charge of my high school reunion a couple months ago. We collected $ via ticket sales on EventBrite to prepay the food vendor. We generated over $600, so sounds like I will get a 1099-K from EventBrite. Every penny was paid from my account directly to the food vendor. How do I go about ensuring that I’m not taxed since it really wasn’t income?
