Extend Graph API for Bookings Services Custom Fields

[Jim_Schott]

I would like to create booking pages using the Graph API and set up normalized services with custom fields that have a list of sub categories for those services.

Example:  Partner and Customer service

Partner services (OptionP1, OptionP2, OptionP3, ...)   

Customer services (OptionC1, OptionC2, OptionC3, ...)

Can be done in the bookings GUI but I cannot find a way to set the options in the API.

Did you find any solution, I am trying the same and can’t find custom fields in graph api
