    What this workflow does

    This workflow goes beyond images. Any file your team works with daily — images, PDFs, Word documents, Excel sheets, PowerPoint decks, CSV exports, ZIP archives — can be uploaded to SharePoint automatically using Microsoft Graph API. The workflow solves the exact problem Microsoft 365 teams face most: files live in too many places (email attachments, Dropbox, local drives, Google Drive) and someone has to manually move them into SharePoint. Here's what happens automatically: → Gets a Microsoft 365 access token via Azure AD OAuth2 → Downloads or receives the file from any source URL → Uploads it directly to the correct SharePoint folder → Returns confirmation with the file's SharePoint location Works with any file type — just change the Content-Type header in the upload node to match: → image/jpeg or image/png for images → application/pdf for PDFs → application/vnd.openxml formats-office document for Word/Excel → application/octet-stream for any binary file  

    Who should use this workflow

    This workflow is for anyone who uploads images often to SharePoint and wants to save time. It helps content managers, marketers, or IT teams who want fewer errors and less manual work. No coding skills are needed to run this in n8n.  

    Tools and services used

    • Microsoft Graph API: To handle authentication and file upload via API.
     
    • Microsoft Azure Active Directory app: To get access credentials (tenant ID, client ID, client secret).
     
    • SharePoint Online: The file storage location where images are uploaded.
     
    • n8n automation platform: To build and run the workflow without coding.
     
    • Public image URL: Source to download an image file for uploading.

    1 Barrier: Setting Up Microsoft 365 Authentication

    Most people get stuck before even touching n8n — the Azure
    AD app registration. Here's the exact setup so you're not
    searching through Microsoft documentation.

    Step 1 — Register an App in Azure AD

    1. Go to portal.azure.com → Azure Active Directory
    2. Click "App Registrations" → "New Registration"
    3. Name it anything (e.g. "n8n SharePoint Upload")
    4. Supported account types: Single tenant (your org only)
    5. Redirect URI: leave blank for now
    6. Click Register

    Step 2 — Get Your Credentials

    From the app overview page, copy:
    → Application (client) ID → this is your CLIENT_ID
    → Directory (tenant) ID → this is your TENANT_ID

    Step 3 — Create a Client Secret

    1. Left menu → "Certificates & Secrets"
    2. Click "New Client Secret"
    3. Set expiry: 24 months recommended
    4. Copy the VALUE immediately — it only shows once
    → This is your CLIENT_SECRET

    Step 4 — Set API Permissions

    1. Left menu → "API Permissions"
    2. Click "Add a permission" → Microsoft Graph → Application permissions
    3. Add: Sites.ReadWrite.All
    4. Click "Grant admin consent for [your org]" — this is required

    Step 5 — Get Your SharePoint Site ID

    In your browser, go to:
    https://[yourtenant].sharepoint.com/sites/[yoursite]/_api/site/id

    Copy the GUID returned — this is your SharePoint Site ID
    used in the Graph API upload URL.

    Once you have TENANT_ID, CLIENT_ID, CLIENT_SECRET, and
    Site ID — paste them into the Set config node and the
    workflow is ready to run.

     

    How the workflow works (Inputs → Processing → Output)

    Inputs

    • Azure AD app credentials: TENANT_ID, CLIENT_ID, CLIENT_SECRET
     
    • Image URL to download (e.g., a public picsum.photos link)
     
    • Target SharePoint folder path
     
    • Filename to save the image as
     

    Processing

    • Manual Trigger: Starts the workflow.
     
    • Set config (sensitive data): Stores tenant ID, client ID, client secret securely in the workflow.
     
    • Authentication: Sends POST request to Microsoft OAuth2 endpoint to get access token.
     
    • Get photo (for testing purposes): Downloads image binary data from the URL.
     
    • Set destination: Sets the folder path and file name for the upload.
     
    • Upload photo: Sends PUT request to Microsoft Graph API to upload the image binary into SharePoint folder.
     

    Output

    The workflow outputs the upload response JSON. It contains file details confirming the image saved correctly. User can check the SharePoint folder manually as well.  

    Beginner step-by-step: How to use this workflow in n8n

    1. Import the workflow

    2. Download the workflow file using the Download button on this page.
     
    2. In the n8n editor, click on "Import from File" and select the downloaded file.
     

    2. Configure credentials

    2. Open the Set config (sensitive data) node.
     
    2. Enter your Azure app's TENANT_ID, CLIENT_ID, and CLIENT_SECRET.
     
    2. Update the TARGET_FOLDER and FILE_NAME fields in the Set destination node as needed.
     

    3. Test the workflow

    2. Click the Manual Trigger node and then select "Execute Workflow".
     
    2. Check the nodes run successfully and the final upload response shows success.
     

    4. Activate for production

    2. Turn on the workflow to enable automatic runs.
     
    2. Optionally, replace the manual trigger with a webhook or scheduled trigger for automation.
      If self hosting n8n, explore self-host n8n for setup and management.  

    Common errors and edge cases

    • 401 Unauthorized: Usually from wrong tenant ID, client ID, or secret. Double-check app registration.
     
    • 404 Not Found on upload: URL path error or missing permissions. Verify folder path and API permissions.
     
    • Image download fails: Image URL invalid or blocked. Test URL separately first.

    What File Types Work With This Microsoft 365 SharePoint Workflow

    This workflow is designed for image uploads by default, but the same Microsoft Graph API endpoint supports almost any file type.

    The only change required is updating the Content-Type header in the upload node.

    File Type
    Content-Type Header Value




    JPEG Image
    image/jpeg


    PNG Image
    image/png


    PDF Document
    application/pdf


    Word Document
    application/vnd.openxmlformats-officedocument.wordprocessingml.document


    Excel Spreadsheet
    application/vnd.openxmlformats-officedocument.spreadsheetml.sheet


    PowerPoint
    application/vnd.openxmlformats-officedocument.presentationml.presentation


    CSV File
    text/csv


    ZIP Archive
    application/zip


    Any Binary File
    application/octet-stream

    The upload node structure remains the same for every file type — only the Content-Type value changes.

    This makes the workflow highly flexible and reusable across your entire Microsoft 365 document system, not just for image uploads.

     

    Ways to customize

    • Change the image source URL in Get photo (for testing purposes) to any valid image.
     
    • Use n8n expressions to create dynamic filenames, like adding timestamps.
     
    • Modify Content-Type in Upload photo for other file types like PDFs.
     
    • Store sensitive values in n8n Credentials for better security instead of Set node.
     
    • Switch to webhook triggers for automatic uploads from external apps.
     

    Summary of benefits and results

    ✓ Saves several hours weekly by removing manual uploads. ✓ Avoids errors caused by manual file handling. ✓ Gives easy automatic uploads into SharePoint using simple n8n setup. ✓ Supports changing image sources and filenames flexibly. ✓ Suitable for non-technical users once set up.  

    Frequently Asked Questions

    How to fix 401 Unauthorized error in the Authentication node?

    This error happens if TENANT_ID, CLIENT_ID, or CLIENT_SECRET are wrong. Check the Azure portal app registration and update credentials exactly.

    What causes 404 Not Found error when uploading the photo?

    This error comes from an invalid SharePoint folder path or missing API permissions. Verify the target folder path and ensure Sites.ReadWrite.All permission is granted.

    Can this workflow upload other file types besides images?

    Yes, by changing the Content-Type header in the upload node and providing the correct binary data, other files like PDFs can be uploaded.

    Is it possible to run this workflow automatically without manual trigger?

    Yes, replace the Manual Trigger node with a Webhook node or schedule trigger to automate workflow runs.
