Create an administrative division.

Administrative divisions are used to divide an organization's territory into separate areas. An organization covering Great Britian for example, might want to have separate divisions for England, Scotland, and Ireland. Each of these countries may have different holidays and need to be administered in different ways.

There is a Create administrative division V2 endpoint designed for greater flexibility in defining non-business days to accommodate specific business requirements. For details about the differences, refer to Platform setup - Holidays and administrative divisions.
