I was invited to speak at APIdays in Madrid, so I travelled internationally to speak. The event gave me a free ticket, and I was not paid to speak. The event assisted with part of my travel and accommodation. My employer did not pay my travel expenses, and I used my PTO to speak. It took me 40 hours to prepare for my 40 minutes speaking slot, and I had a great time. I'm a man who has been speaking for 2 years. This was a not for profit event.
