SharePoint via Microsoft Graph API

Challenge

Many organizations rely on SharePoint for data management, but integrating that data into modern cloud environments is harder than it should be. Manual processes are inefficient, error-prone, and expose sensitive data along the way. The team needed a secure, automated ingestion pipeline that moves SharePoint data into Azure Storage with no manual handoffs and no exposed credentials.

Approach

We built an automated pipeline using Microsoft Graph API and Azure Data Factory. Authentication is end-to-end secure: a service principal secret is retrieved from Azure Key Vault to mint a bearer token for Graph API access — credentials never touch source code, config files, or process logs.

With the token in hand, the pipeline queries Graph API for the relevant SharePoint drive ID, then Azure Data Factory copies the files into an Azure Storage Account. The whole flow is reproducible: same secret rotation, same Graph API contract, same ADF pipeline — no manual steps to remember.

Outcomes

• Enhanced security: authentication via Azure Key Vault and short-lived bearer tokens
• Automated end-to-end data flow — manual SharePoint extraction eliminated
• Reliable, scalable pipeline via Azure Data Factory
• Reusable pattern for any SharePoint site or document library
• Auditable file movements with no exposed credentials
