# Microsoft Graph API
[Microsoft Graph](https://developer.microsoft.com/en-us/graph/graph-explorer) or [https://aka.ms/ge](https://aka.ms/ge) or [https://ge.cmd.ms/](https://ge.cmd.ms/)
### Graph Explorer
```powershell
# Default Query
https://graph.microsoft.com/v1.0/me
# Filtered Attributes
https://graph.microsoft.com/v1.0/me?$select=id,userPrincipalName
# User.Read.All - Permission is needed to run the below query
https://graph.microsoft.com/v1.0/users?$select=id,userPrincipalName
# Get Top three users
https://graph.microsoft.com/v1.0/users?$top=3&$select=id,userPrincipalName
```
### Retrieve users from the Microsoft Graph API using a User account (Tested with Global Admin)
```powershell
$url = "https://graph.microsoft.com/v1.0/users"
$token = "*************************************"
$header = @{Authorization = "Bearer $token"}
invoke-RestMethod -uri $url -Headers $header
$result =invoke-RestMethod -uri $url -Headers $header
$result.value
$result.value | Measure-Object
$result.value | Select-Object id,userPrincipalName
```
### Retrieve AAD users & Azure resources from the Microsoft Graph API using an Azure Service Principal
#### Above permissions are needed for that Application to work all the scripts mentioned here.
- [**scope**](https://graph.microsoft.com/.default) uri is needed to query the AAD users & [**resource**](https://management.core.windows.net) uri is needed to query the AZ resources.
- Authorization endpoint is not needed when "**grant_type**" is "**client_credentials**". The token endpoint is only needed. **Token type: Access_Token**
- Token Endpoint (V1) : [https://login.microsoftonline.com//oauth2/token](https://login.microsoftonline.com//oauth2/token) - Use that for AZ Resouces
- Token Endpoint (V2) : [https://login.microsoftonline.com//oauth2/v2.0/token](https://login.microsoftonline.com//oauth2/v2.0/token) - Use that for AAD Users
```powershell

### Microsoft Azure REST API's using Client credential flow
```powershell
# Microsoft Azure REST API's using Client credential flow
Connect-AzAccount -Identity
$tenantid = Get-AzKeyVaultSecret -VaultName "" -Name "" -AsPlainText
$openid = Invoke-RestMethod -Uri "https://login.microsoftonline.com/$tenantid/.well-known/openid-configuration"

$url = "https://management.azure.com/subscriptions//resources?api-version=2021-04-01"
$az_resources = Invoke-RestMethod $url -Headers @{Authorization = "Bearer $($access_token)"} -Method Get
```
### Retrieve AAD Users from the Microsoft Graph PowerShell using System Assigned Managed Identity(MSI) & KeyVault
```powershell
#Script is tested from Azure Automation Account & Azure VM
#Requires -Module @{ ModuleName = 'Az.Accounts'; ModuleVersion = '2.13.2' }
#Requires -Module @{ ModuleName = 'Az.KeyVault'; ModuleVersion = '5.0.1' }
#Requires -Module @{ ModuleName = 'Microsoft.Graph.Authentication'; ModuleVersion = '2.10.0' }
#Requires -Module @{ ModuleName = 'Microsoft.Graph.Users'; ModuleVersion = '2.10.0' }
Connect-AzAccount -Identity
$ApplicationId = Get-AzKeyVaultSecret -VaultName "" -Name "" -AsPlainText
$SecuredPassword = Get-AzKeyVaultSecret -VaultName "" -Name "" -AsPlainText
$tenantID = Get-AzKeyVaultSecret -VaultName "" -Name "" -AsPlainText
$SecuredPasswordPassword = ConvertTo-SecureString -String $SecuredPassword -AsPlainText -Force
$ClientSecretCredential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList `
$ApplicationId, $SecuredPasswordPassword
Connect-MgGraph -TenantId $tenantID -ClientSecretCredential $ClientSecretCredential -NoWelcome
Get-MgUser | Select-Object DisplayName, Id, UserPrincipalName
```
### Certificate based authentication using Service principle name
```powershell
# Permissions are needed as per the above screenshot.
$client_id = "*****************"
$tenant_id = "********************"
$thumb_print = (Get-ChildItem "Cert:\LocalMachine\my" | Where-Object { $_.Subject -eq "CN=*******" }).Thumbprint
Connect-MgGraph -ClientId $client_id -TenantId $tenant_id -CertificateThumbprint $thumb_print
$result = Invoke-MgGraphRequest -Method GET -Uri "https://graph.microsoft.com/v1.0/users"
$result.value
$result.value | Select-Object id,displayName,userPrincipalName
```
### Create an Azure Application using Graph API
```powershell
# 'Application.ReadWrite.OwnedBy' - Permission is required
$client_id = "*****************"
$tenant_id = "********************"
$thumb_print = (Get-ChildItem "Cert:\LocalMachine\my" | Where-Object { $_.Subject -eq "CN=*******" }).Thumbprint
Connect-MgGraph -ClientId $client_id -TenantId $tenant_id -CertificateThumbprint $thumb_print
New-MgApplication -DisplayName

Connect-MgGraph -ClientId $connection.ApplicationID `
-TenantId $connection.TenantID `
-CertificateThumbprint $connection.CertificateThumbprint
}
catch {
Write-Error -Message $_.Exception
throw $_.Exception
}
# Set the subscription context
