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 SCIM 2 Users 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. Note that access using Customer Groups is not covered by these APIs.
