Custom fields

The system supports creating an unlimited number of custom fields that can be used to extend various objects with additional, user-defined data. Custom fields can have different data types, such as:

text
select
checkboxes
multiselect
(and other supported input types)

For field types that require predefined choices (e.g., select, checkboxes, multiselect), the API allows you to define any number of selectable options.

Each custom field must be assigned to exactly one supported object type. Custom fields can be attached to the following objects:

Booking
Person
ApplicationForm
Waiver
BookingInquiry
Product

Once defined, custom field values are stored directly inside the corresponding object, under the JSON attribute custom_fields. This attribute contains a key–value structure representing the custom field identifiers and their assigned values.

This mechanism enables flexible data modeling and the ability to tailor object structures to specific business needs without modifying the core schema.

When a CustomField is deleted, all previously saved values associated with that field remain stored within the objects’ custom_fields JSON attribute. The system does not automatically remove or modify these legacy values, ensuring that historical data remains intact unless explicitly updated or cleaned up by the client.
