Azure Portal tenant selection

gistfile1.txt

Some of the Azure  Portal views support injection of tenant or login information. This is useful when creating portal links to some particular tenant.

## query parameters

Query parameter usage is undocumented and is highly possible that on some of the views support those

* tenantHint
  * Not sure of works at all
* loginHint
  * Works only portal main page

## URL Path

Both notations works on portal main page

* https://portal.azure.com/{tenant name or GUID}#
* https://portal.azure.com/@{tenant name or GUID}

For most of the resource specific links Portal is using `https://portal.azure.com/@{tenant name or GUID}` notation.

## URL examples from Portal

* Home: https://portal.azure.com/#home
* Service blade: https://portal.azure.com/#view/Microsoft_Azure_Support/HelpAndSupportBlade/~/overview
* Other service blade: https://portal.azure.com/#view/Microsoft_Azure_Billing/SubscriptionsBladeV2
* Subscription: https://portal.azure.com/#@{tenant.onmicrosoft.com or domain}/resource/subscriptions/{subscription ID}/overview
* Resource: https://portal.azure.com/#@{tenant.onmicrosoft.com or domain}/asset/Microsoft_Azure_KeyVault/KeyVault/subscriptions/{subscription ID}/resourceGroups/{resource group name}/providers/Microsoft.KeyVault/vaults/{resource name}
* Activity log: 
  * root management group: https://portal.azure.com/#view/Microsoft_Azure_Resources/ManagmentGroupDrilldownMenuBlade/~/activitylog/tenantId/{tenant ID}/mgId/{management group id}/mgDisplayName/{management group display name}/mgCanAddOrMoveSubscription~/true/mgParentAccessLevel/Not%20Authorized/defaultMenuItemId/overview/drillDownMode~/true
  * management group: https://portal.azure.com/#view/Microsoft_Azure_Resources/ManagmentGroupDrilldownMenuBlade/~/activitylog/tenantId/{tenant ID}/mgId/{management group id}/mgDisplayName/{management group displayname}/mgCanAddOrMoveSubscription~/false/mgParentAccessLevel/Reader/defaultMenuItemId/overview/drillDownMode~/true
  * subscription: https://portal.azure.com/#@{tenant.onmicrosoft.com or domain}/resource/subscriptions/{tenant ID}/eventlogs
  * resource group: https://portal.azure.com/#@{tenant.onmicrosoft.com or domain}/resource/subscriptions/{subscription ID}/resourceGroups/{resource group name}/eventlogs
* Deployments:
  * root management group: https://portal.azure.com/#view/Microsoft_Azure_Resources/ManagmentGroupDrilldownMenuBlade/~/deployments/tenantId/{tenant ID}/mgId/{management group id}/mgDisplayName/{management group display name}/mgCanAddOrMoveSubscription~/true/mgParentAccessLevel/Not%20Authorized/defaultMenuItemId/overview/drillDownMode~/true
  * management group: https://portal.azure.com/#view/Microsoft_Azure_Resources/ManagmentGroupDrilldownMenuBlade/~/deployments/tenantId/{tenant ID}/mgId/{management group id}/mgDisplayName/{management group display name}/mgCanAddOrMoveSubscription~/false/mgParentAccessLevel/Reader/defaultMenuItemId/overview/drillDownMode~/true
  * subscription: https://portal.azure.com/#@{tenant.onmicrosoft.com or domain}/resource/subscriptions/{subscription ID}/subdeployments
  * resource group: https://portal.azure.com/#@{tenant.onmicrosoft.com or domain}/resource/subscriptions/{subscription ID}/resourceGroups/{resource group name}/deployments
  
 ### Notes for management groups
* for root management group {management group id} = {tenant id} and {management group display name} = "Tenant%20Root%20Group" by default
* for other management groups {management group id} = {short id} and {management group display name} = {longer display name}
* Management group display names can be changed
* Management group links contains too much information for easy programmatic creation
  * mgParentAccessLevel, mgCanAddOrMoveSubscription, drillDownMode are mandatory parameters for view
