API key
The account owner creates API keys on the Developers page and picks the scopes (events, orders, attendees, check-in) and validity. The key is shown only once; if you lose it, revoke it and create a new one. Up to 10 keys can be active at a time.
What you can do
Pull your events, orders and attendees into your own system, or verify entries with your own scanner or turnstile system. Each key is limited to 120 requests per minute; details are in the public API docs.
CSV files
Orders, guests, door sales and entry codes download as CSV per event; the files open correctly in Excel, Turkish characters included.
Security
Don't share keys with anyone and revoke the ones you don't use. Account owners get an email for every new key.
