Partner organizations that manage their customers through the Webex Partner Hub can utilize this API to assign or unassign partner administrator roles to their users, as well as to assign or unassign customer organizations to specific partner administrators. To manage other partner administrators within an organization, the user must have the Partner Full Administrator role. Note that the users being managed must belong to the partner's own organization. For instructions on creating a user, refer to the People API. The authorizing administrator must have the spark-admin:organizations_read scope for read operations and the spark-admin:organizations_write scope for write operations. Users with the Partner Full Admin role automatically have the ability to manage all customers. Assignees specified in this API should be selected from the list of users with the Partner Admin role.
