Commands to grant Azure application access to the Microsoft SharePoint site

Use one of the following three methods to grant your registered Azure application write access to the Microsoft SharePoint site at the site level, using the Microsoft Graph API.

Note:

These commands are provided for reference only and are not sourced from an external tool vendor. Only one method is required — choose the method that best matches what the Azure administrator already has installed. All three methods achieve the same result.

Table 1. Values to replace in the commands below

Placeholder	Example value	Where to find it
YOUR_TENANT_ID	xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx	Azure App Registration > Overview > Directory (tenant) ID
YOUR_CLIENT_ID	yyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy	Azure App Registration > Overview > Application (client) ID
YOUR_CLIENT_SECRET	abc123XYZ~mySecretValue	Azure App Registration > Certificates & secrets > Client secrets > Value
YOUR_TENANT / TENANT_NAME	contoso	The Microsoft 365 tenant name — the subdomain before .sharepoint.com
YOUR_SITE_NAME / SITE_NAME	MSIMSite	The Microsoft SharePoint site name — the relative path segment after /sites/
APP_REGISTRATION_DISPLAY_NAME	Microsoft SharePoint Graph	The display name entered when registering the App
YOUR_TOKEN_FROM_STEP1	eyJ0eXAiOiJKV1Qi...	Curl method only — the access_token value from the Step 1 response
YOUR_SITE_ID_FROM_STEP_2	contoso.sharepoint.com,abc123,def456	Curl method only — the id value from the Step 2 response

Method 1 — Curl

Replace all placeholders with values from the table above before executing. Copy the access_token from Step 1 and the site id from Step 2 for use in Step 3.

# Step 1: Get OAuth Token for the Registered Azure Application
curl --location --request GET 'https://login.microsoftonline.com/YOUR_TENANT_ID/oauth2/v2.0/token' \
    --header 'accept: application/json' \
    --data-urlencode 'grant_type=client_credentials' \
    --data-urlencode 'client_id=YOUR_CLIENT_ID' \
    --data-urlencode 'client_secret=YOUR_CLIENT_SECRET' \
    --data-urlencode 'scope=https://graph.microsoft.com/.default'
# From the response JSON, copy the access_token value -- this becomes YOUR_TOKEN_FROM_STEP1

# Step 2: Retrieve SharePoint Site ID
curl --location 'https://graph.microsoft.com/v1.0/sites/YOUR_TENANT.sharepoint.com:/sites/YOUR_SITE_NAME' \
    --header 'Authorization: Bearer YOUR_TOKEN_FROM_STEP1'
# From the response JSON, copy the id value -- this becomes YOUR_SITE_ID_FROM_STEP_2

# Step 3: Grant Azure Application Permissions to the SharePoint Site
curl --location 'https://graph.microsoft.com/v1.0/sites/YOUR_SITE_ID_FROM_STEP_2/permissions' \
    --header 'Content-Type: application/json' \
    --header 'Authorization: Bearer YOUR_TOKEN_FROM_STEP1' \
    --data '{"roles": ["write"], "grantedToIdentities": [{"application": {"id": "YOUR_CLIENT_ID", "displayName": "APP_REGISTRATION_DISPLAY_NAME"}}]}'

Method 2 — Azure CLI

Replace the placeholder variable values at the top of the script with your actual values, then execute the full script. Requires the Azure CLI. For installation, see Install Azure CLI.

#!/bin/bash
# Replace placeholder values with your actual values
TENANT_ID="YOUR_TENANT_ID"
CLIENT_ID="YOUR_CLIENT_ID"
CLIENT_SECRET="YOUR_CLIENT_SECRET"
TENANT_NAME="YOUR_TENANT"  # e.g., contoso
SITE_NAME="YOUR_SITE_NAME"
APP_DISPLAY_NAME="APP_REGISTRATION_DISPLAY_NAME"

# Authenticate with Azure AD (without requiring a subscription)
az login --service-principal -u "$CLIENT_ID" -p "$CLIENT_SECRET" --tenant "$TENANT_ID" --allow-no-subscriptions

# Get access token for Microsoft Graph API
ACCESS_TOKEN=$(az account get-access-token --resource https://graph.microsoft.com --query accessToken --output tsv)
if [ -z "$ACCESS_TOKEN" ]; then echo "Failed to retrieve access token." >&2; exit 1; fi

# Fetch SharePoint Site ID
SITE_ID=$(az rest --method GET --uri "https://graph.microsoft.com/v1.0/sites/$TENANT_NAME.sharepoint.com:/sites/$SITE_NAME" --headers "Authorization=Bearer $ACCESS_TOKEN" --query "id" --output tsv)
if [ -z "$SITE_ID" ]; then echo "Failed to retrieve SharePoint Site ID." >&2; exit 1; fi

# Grant App Permissions to SharePoint Site
az rest --method POST --uri "https://graph.microsoft.com/v1.0/sites/$SITE_ID/permissions" \
    --headers "Authorization=Bearer $ACCESS_TOKEN" "Content-Type=application/json" \
    --body "{\"roles\": [\"write\"], \"grantedToIdentities\": [{\"application\": {\"id\": \"$CLIENT_ID\", \"displayName\": \"$APP_DISPLAY_NAME\"}}]}"

Method 3 — PowerShell

Replace the placeholder variable values at the top of the script with your actual values, then execute the full script. For installation, see Install PowerShell.

# Define Variables -- Replace placeholder values with actual values
$tenantId = "YOUR_TENANT_ID"
$clientId = "YOUR_CLIENT_ID"
$clientSecret = "YOUR_CLIENT_SECRET"
$tenantName = "YOUR_TENANT"
$siteName = "SITE_NAME"
$appDisplayName = "APP_REGISTRATION_DISPLAY_NAME"

try {
    # Step 1: Get Access Token
    $tokenResponse = Invoke-RestMethod -Method Post -Uri "https://login.microsoftonline.com/$tenantId/oauth2/v2.0/token" -Body @{ grant_type = "client_credentials"; client_id = $clientId; client_secret = $clientSecret; scope = "https://graph.microsoft.com/.default" } -ContentType "application/x-www-form-urlencoded"
    $accessToken = $tokenResponse.access_token
    if (-not $accessToken) { throw "Failed to retrieve access token." }

    # Step 2: Get SharePoint Site ID
    $siteResponse = Invoke-RestMethod -Uri "https://graph.microsoft.com/v1.0/sites/$tenantName.sharepoint.com:/sites/$siteName" -Method Get -Headers @{ "Authorization" = "Bearer $accessToken" }
    $siteId = $siteResponse.id
    if (-not $siteId) { throw "Failed to retrieve SharePoint Site ID." }

    # Step 3: Grant App Permissions
    $body = @{ roles = @("write"); grantedToIdentities = @(@{ application = @{ id = $clientId; displayName = $appDisplayName } }); displayName = "$appDisplayName" } | ConvertTo-Json -Depth 10
    Invoke-RestMethod -Uri "https://graph.microsoft.com/v1.0/sites/$siteId/permissions" -Method Post -Headers @{ "Authorization" = "Bearer $accessToken"; "Content-Type" = "application/json" } -Body $body
} catch { Write-Host "Error: $_" -ForegroundColor Red; exit 1 }
