Add a tenant to a multitenant organization. The administrator of an owner tenant has the permissions to add tenants to the multitenant organization. The added tenant is in the pending state until the administrator of the added tenant joins the multitenant organization by submitting a join request. A tenant can be part of only one multitenant organization.
Choose the permission or permissions marked as least privileged for this API. Use a higher privileged permission or permissions only if your app requires it. For details about delegated and application permissions, see Permission types. To learn more about these permissions, see the permissions reference.
