Booking API Bookings not working in sandbox

I am receiving the following errors in my sandbox when trying to get bookings thru API. When I switch to production I can get the bookings object back. How do I activate appointments/bookings in sandbox?

Edit: I also get the error in the API Explorer sandbox

errors: [
[Object: null prototype] {
category: ‘AUTHENTICATION_ERROR’,
code: ‘UNAUTHORIZED’,
detail: ‘Merchant not onboarded to Appointments’
}
]

That authentication error is caused by not having the correct permissions when calling the Bookings API. You’ll need to make sure you have the correct Seller-level and buyer-level permissions to call the API. :slightly_smiling_face:
