Custom Webhook Processing for SharePoint List Events Using Azure Functions

Use Case

When an item is added, updated, or deleted in a SharePoint Online list, an Azure Function processes the event and updates an external system (e.g., a CRM, database, or sends notifications via Teams/Email)


Solution Architecture

  1. SharePoint Webhook: Subscribes to list events (item added, updated, deleted).
  2. Azure Function (HTTP Trigger): Receives the webhook notification.
  3. Graph API / SharePoint REST API: Retrieves item details.
  4. External System Update: Pushes data to SQL, CRM, or sends notifications.

Steps to Implement

Step 1: Create an Azure Function App

  1. Go to Azure Portal → Function App → Create
  2. Choose Runtime Stack → .NET / Node.js / Python (as per your preference)
  3. Select Hosting Plan → Consumption Plan (Pay-as-you-go)
  4. Deploy and get the Function URL

Step 2: Create an Azure Function to Receive Webhook Events

C# Code for Azure Function (HTTP Trigger):
