n8n + SharePoint Integration: 5 Powerful Workflows You Can Build

For organizations relying on Microsoft 365, SharePoint serves as the central hub for files, lists, and document collaboration. However, keeping SharePoint connected to outside systems like CRMs, databases, and communication tools often requires tedious manual updates or expensive, rigid integration platforms. By pairing SharePoint with n8n, you can break through these limitations, building highly customizable, event-driven pipelines that automate document management, data synchronization, and internal notifications. In this guide, we will explore five production-ready workflows that bridge the gap between your enterprise data and Microsoft’s ecosystem, helping you reach maximum efficiency without writing thousands of lines of code.

How to Connect SharePoint to n8n

To begin constructing these automations, you need a secure link between your n8n instance and your Microsoft 365 environment. Because SharePoint uses Microsoft Graph API under the hood, we must establish authentication via Microsoft OAuth2.

Follow these steps to configure your credentials:

1. Register an Application in Azure Active Directory (Microsoft Entra ID):
   • Log in to the Azure Portal and navigate to App registrations.
   • Click on New registration, give your application a clear name (for example, n8n SharePoint Integration), and choose the appropriate tenant type.
   • In the Redirect URI section, select Web as the platform. Enter your n8n redirect URL. If you are hosting on our platform, this will look like https://yourname.n8nautomation.cloud/rest/oauth2-credential/callback.
   • Under API permissions, add Microsoft Graph delegated permissions. You will need Files.ReadWrite.All, Sites.ReadWrite.All, and User.Read to ensure your workflow can read, write, and list resources.
   • Go to Certificates & secrets, generate a new client secret, and copy the value immediately. This is the only time it will be shown.
2. Configure the Microsoft Credentials inside n8n:
   • Open your n8n canvas and navigate to the Credentials menu on the left sidebar.
   • Click Add Credential, search for Microsoft SharePoint OAuth2, and select it.
   • Paste your Azure Client ID (Application ID), Client Secret, and your Tenant ID (if you are restricting access to a single organization).
   • Click Sign in with Microsoft, consent to the permissions in the popup window, and verify that the status changes to green indicating successful connection.
3. Add and Verify the Microsoft SharePoint Node:
   • Create a new workflow, click the + icon, and search for the Microsoft SharePoint node.
   • Select the credential you just saved.
   • Set the Resource to Document Library, set the Operation to Get All, and run the node to confirm that n8n can successfully retrieve files from your root SharePoint directories.

Workflow 1: Auto-Ingesting Email Attachments to SharePoint Folders

Organizations receive hundreds of PDF invoices, client contracts, and reports via email every day. Manually downloading these files and organizing them into nested SharePoint directories takes hours and introduces the risk of files being misplaced. This workflow listens for inbound emails, filters them based on criteria, and uploads the attachments directly into the correct SharePoint folder.

How It Works

The automation begins with an email trigger node, such as the Microsoft Outlook Trigger or the Gmail Trigger, listening for new messages. Once an email arrives, n8n processes the input to determine if attachments exist. The system uses the following node sequence to handle incoming files:

1. Email Trigger: Configured to fetch new messages and download binary data (attachments) automatically.
2. Switch Node: Evaluates the email sender or subject line. For instance, if the subject contains Invoice, it routes the item to path A; if it contains Contract, it routes to path B.
3. Microsoft SharePoint Node: Receives the binary data. It is configured with the operation Upload File. The file path is determined dynamically using expression templates, such as /Shared Documents/Invoices/{{ $today.format('yyyy-MM') }}/{{ $json.attachmentName }}.

Real-World Example

A construction company receives delivery notes from various suppliers via email. They configured an n8n workflow that triggers every time an email lands in [email protected]. The workflow checks if the attachment is a PDF. If it is, the workflow extracts the supplier name from the email domain (e.g., supplier-a.com) and deposits the document inside /Shared Documents/Suppliers/Supplier-A/2026/. This keeps their document library structure organized automatically, saving hours of manual dragging and dropping.

Pro Tips

When working with email attachments, ensure you check the "All Attachments" setting in the mail trigger node. This outputs the attachments as binary properties. In the SharePoint node, specify the precise binary property name (usually attachment_0 or similar, depending on how n8n represents the attachment) under the "Binary Property" parameter. If an email has multiple attachments, use the Split in Batches node to iterate through them sequentially so that no files are missed during the upload process. This prevents folder overwrites and keeps execution logs tidy.

Workflow 2: Syncing SharePoint Lists to PostgreSQL Databases

SharePoint Lists are often used by operations teams as lightweight internal databases. However, because databases like PostgreSQL or MySQL are the source of truth for engineering teams and client dashboards, maintaining consistency between these two environments is critical. This workflow ensures that whenever a team member adds or updates an item in a SharePoint List, those changes propagate immediately to a production database.

How It Works

This workflow operates on a scheduled polling or webhook trigger. By utilizing standard n8n database integration mechanics, it creates a reliable, high-performance link between collaborative list records and relational tables. The step-by-step pipeline includes:

1. Schedule Trigger: Runs every 10 minutes to pull fresh entries, or a Webhook node that accepts immediate event notifications from SharePoint.
2. Microsoft SharePoint Node: Configured to Get All items from a specific List ID. We can apply filter query parameters such as $filter=Modified ge datetime'{{ $prevExecutionTime }}' to retrieve only the list entries that changed since the last execution.
3. PostgreSQL Node: Uses the Upsert operation. By defining a conflict key (for example, the SharePoint item ID), this node automatically inserts new records or updates existing rows if they already exist in the database table.

Real-World Example

An inventory management team uses a SharePoint List to log new equipment arrivals. When an operative adds a laptop to the list, n8n detects the modification. Within seconds, it updates the primary PostgreSQL table that feeds the internal developer portal, keeping both the logistics team and the IT deployment team fully aligned without duplicate manual entry.

Pro Tips

SharePoint returns complex nested JSON models for list items, containing technical metadata columns (like OData identifiers). Use the Edit Fields (formerly Set) node or the Code node with minimal JavaScript to clean up the keys before passing them to the database node. For example, flattening the payload from $json.fields.Title to just $json.title makes database mapping much cleaner and prevents SQL execution errors during production upserts.

Workflow 3: Driving Document Approvals via Slack

Before a draft document in SharePoint is published or sent to a client, it typically requires a manager's sign-off. Leaving these approvals inside email threads creates bottlenecks. This workflow monitors a SharePoint folder for new drafts, sends an approval request with interactive buttons to a Slack channel, and moves the document to an approved folder once clicked.

How It Works

This process uses intermediate wait steps to handle human intervention, allowing the workflow state to persist gracefully over minutes or days. The process runs as follows:

1. Microsoft SharePoint Node (Trigger): Activates when a new file is added to the /Shared Documents/Drafts directory.
2. Slack Node: Sends a message to an operations channel containing the document name, a link to view it, and two interactive block buttons: "Approve" and "Reject".
3. Wait Node: Pauses the execution thread until the Slack button is clicked, which sends an interactive payload back to n8n’s webhook URL.
4. If Node: Evaluates the payload. If "Approve" was selected, the workflow moves to the positive branch.
5. Microsoft SharePoint Node (Move): Relocates the file from the Drafts directory to /Shared Documents/Approved/ and updates the file's metadata status field to indicate authorization is complete.

Real-World Example

A legal consultancy puts contract drafts inside a SharePoint folder. The moment a document is saved, the internal review team gets a Slack notification. Once a senior partner hits the "Approve" button directly within Slack, the document is moved to the client-facing directory, and a notification is sent back to the draft author confirming the document is ready.

Pro Tips

To implement this reliably, make sure to use n8n’s webhook-based interactive components for Slack. When creating the buttons, configure the action value to contain the original SharePoint file ID. This allows your webhook response handler to identify exactly which file needs to be relocated when the partner clicks approval, keeping the workflow stateless and robust even when multiple files are awaiting approval simultaneously.

Workflow 4: AI-Powered PDF Content Extraction and Metadata Tagging

Many documents stored in SharePoint are unstructured PDFs, such as receipts, invoices, or customer letters. Finding specific files later is difficult if they are not indexed or tagged. By passing these documents through an AI vision or text model, we can parse the content, extract structured data, and automatically apply metadata tags in SharePoint.

How It Works

This pipeline combines document retrieval with advanced AI nodes to construct an automated tagging engine. The setup includes:

1. Microsoft SharePoint Node: Automatically triggers when a new PDF is added to an unorganized root folder. It downloads the binary file.
2. Extract PDF Content Node: Converts the binary document data into plain text.
3. OpenAI Chat Model Node: Receives the extracted text along with a strict prompt: "Extract the customer name, total invoice value, and invoice date from this text. Return only valid JSON with keys: customer, total, date."
4. Code Node: Parses the JSON output from the AI model to ensure fields are typed correctly.
5. Microsoft SharePoint Node (Update): Updates the list item corresponding to the document, filling out the metadata columns (Customer, Amount, Date) with the AI-generated values.

Real-World Example

An accounting department uploads scanned PDF receipts to SharePoint. The AI-enabled n8n pipeline reads the scans, identifies that a receipt is from a specific vendor, extracts the exact tax total, and updates the SharePoint document columns. Employees can now search and filter their entire document library by vendor name or expense total directly within SharePoint’s interface, avoiding manual indexing completely.

Pro Tips

If your PDFs are low-quality images rather than digital text, the standard PDF parser might fail. In these situations, send the binary data to a node with OCR capabilities, such as AWS Textract, Google Cloud Vision, or an AI Vision model (like GPT-4o). Pass the file directly as an image input, prompting the model to perform the OCR and extract structured values simultaneously. This keeps your tagging operational even for poorly lit smartphone photos of receipts.

Workflow 5: Bi-Directional File Synchronization with Google Drive

Many companies use both Microsoft 365 and Google Workspace across different teams. If the creative department operates exclusively in Google Drive while the finance team works within SharePoint, manual file moving becomes a daily chore. This workflow bridges the divide, ensuring that files added or modified in one platform are replicated in the other.

How It Works

This setup utilizes parallel triggers to handle updates on both ends, functioning as a persistent bridge. The architecture is split into two logical paths:

1. Google Drive Trigger Node: Listens for new files in a specified Google Drive folder.
   • Downloads the file data.
   • Passes the binary stream to the Microsoft SharePoint Node, which uploads it to a corresponding SharePoint directory.
2. Microsoft SharePoint Trigger Node: Listens for new files in the designated SharePoint folder.
   • Downloads the file data.
   • Passes the binary stream to the Google Drive Node to save it in the designated Google Drive folder.
3. Filter Nodes: Crucial to prevent infinite feedback loops. The filter nodes verify that the file upload was not initiated by the n8n bot account itself before running the sync step.

Real-World Example

A marketing agency works with external freelancers who upload campaign assets to Google Drive. Once those assets are reviewed, an n8n workflow replicates them inside the corporate SharePoint instance, where the client’s internal compliance teams can access and review them without requiring access to the agency’s private Google folders.

Pro Tips

To prevent the system from getting stuck in an infinite synchronization loop, use metadata tags or custom file prefixes. For instance, when n8n uploads a file to Google Drive, it can prefix the name with [Sync] or append a specific property. Configure your triggers to immediately filter out and terminate any execution where this flag is present, keeping the synchronization stable and reliable without generating duplicate execution costs.
