A new endpoint is available to retrieve custom group rate restrictions by room type for a specific group. Requires the Custom Group feature to be enabled in Admin.

Two restriction types are supported:

• closed_arrival – indicates whether arrivals are blocked on the specified date
• min_length_of_stay – specifies the minimum number of nights required for bookings arriving on the specified date

Both restriction types can be applied to individual dates or date ranges and may vary by room type. If custom rate restrictions are not activated for the hotel, the request returns HTTP 422.

Example response:
