Under Practice & system → Integrations you set up connections with other systems. This is part of the Gym plan and higher, and only the owner can do it.

Payouts via Stripe. The first tile is about your payouts. See Setting up payouts for your business.

The public API. If you want your website to show your class timetable, or your turnstile or accounting to access your data, you create an API key. Give it a name, so you know later what it’s for, and choose what it’s allowed to do. A key that isn’t allowed to do anything has no purpose.

For your developer. Every call goes with the key in the header: Authorization: Bearer fit_live_…. Ask us for the technical documentation.
