Arbox Auto-Booking

Automatically books fitness classes at the exact moment booking opens -- before popular classes sell out.

• Node.js v16+
• An Arbox account at a gym using the Arbox platform

1. Clone the repo

git clone https://github.com/WolfikOz/arbox-auto-booking.git
cd arbox-auto-booking

2. Find your gym's IDs

You need three IDs specific to your gym. Get them by opening Chrome DevTools, logging into the Arbox web app, and booking a class manually. Look for these values in the request payloads:

• ARBOX_WHITELABEL: Your gym's subdomain slug (e.g. mygym-tlv)
• ARBOX_BOX_ID: Your gym's numeric box ID
• ARBOX_MEMBERSHIP_ID: Your membership record ID
• Location IDs: Per-room IDs in the schedule API response

3. Configure your schedule

cp arbox-schedule.example.json arbox-schedule.json

Edit arbox-schedule.json with your classes, times, location IDs, and booking window.

4. Set environment variables

export ARBOX_EMAIL="your@email.com"
export ARBOX_PASSWORD="yourpassword"
export ARBOX_WHITELABEL="your-gym-slug"
export ARBOX_BOX_ID="12345"
export ARBOX_MEMBERSHIP_ID="67890"

5. Test with dry run

ARBOX_DRY_RUN=true node arbox-book.js

6. Run for real

node arbox-book.js

The script uses a pre-fetch + wait strategy:

1. Before booking opens: fetch the full schedule
2. Wait until the exact booking window time
3. Fire the booking POST at T+0 with no fetch latency
