What do you need?
You need administrator access to Flux and access to CallingBird. Collect two different values in Flux: the practice slug from Online appointments and an API token from Appointment widget.
Prepare Flux
- 1Open Online appointments in Flux
Click the gear icon in the left menu and choose Online appointments under Appointments. Flux describes this route as Settings > Appointments > Online appointments.
- 2Copy the practice slug
Find the base URL of your online appointments. The practice slug is only the part after the base URL; don't copy the full URL.

The part after the base URL is the practice slug you enter in CallingBird. - 3Open Appointment widget
Go back to Settings and open Appointment widget. This is where Flux manages the API tokens for the appointment widget.
