Question details

User needs to include resource identifying data in Microsoft Graph webhook change notifications for a OneDrive root drive.

Fix Microsoft Graph Webhook Notification Missing Resource Data

Product: Microsoft Graph API
Device & OS: not provided
Scenario: Setting up a Microsoft Graph API subscription to monitor changes in a OneDrive drive root and receiving notifications.
Observed behavior: The webhook successfully sends change notifications, but the payload lacks the resourceData object required to identify which specific file was changed.

Before you start

Verify that your application has the correct permissions configured in Azure Active Directory (Azure AD) and that you have access to your subscription creation request payload.

Solution 1Recommended

Configure Subscription for Rich Notifications

Configure your Microsoft Graph subscription to include resource data by enabling the includeResourceData property and providing an encryption certificate.

By default, Microsoft Graph change notifications do not include resource data for security reasons. To receive 'rich notifications' that include the resourceData payload, you must explicitly configure your subscription to encrypt the data.

Enable includeResourceData

In your subscription creation POST request, set the 'includeResourceData' property to 'true'.

Provide an encryption certificate

Add the 'encryptionCertificate' and 'encryptionCertificateId' properties to your subscription request. Microsoft Graph uses this public key to encrypt the resource data before sending it to your webhook endpoint.

Verify endpoint decryption

Ensure your webhook endpoint is programmed to parse and decrypt the incoming payload using the corresponding private key associated with the encryption certificate.

Configure Subscription for Rich Notifications

Important Note: Not all Microsoft Graph resources support rich notifications. Refer to the official Microsoft Graph change-notification documentation to confirm if the specific OneDrive resource supports the includeResourceData flag.

Solution 2

Consult the Microsoft Graph Developer Community

If your subscription is configured correctly but resource data is still missing, post your specific payload and API version to the Microsoft Q&A forum for advanced troubleshooting.

Frequently Asked Questions

Why do my Microsoft Graph webhook notifications only show basic information?

For security and privacy reasons, Microsoft Graph notifications only send basic state change alerts by default. To see exactly what changed (resource data), you must request rich notifications by configuring encryption parameters.

What parameters are required to include resourceData in Microsoft Graph notifications?

You must set the 'includeResourceData' property to true, provide a valid base64-encoded public key in the 'encryptionCertificate' property, and specify an 'encryptionCertificateId' in your subscription creation request.

Are rich notifications supported for OneDrive drive root changes?

Support for rich notifications varies by resource endpoint. You must check the latest Microsoft Graph API documentation for 'driveItem' or 'drive' resources to see if they currently support the includeResourceData property. If they do not, you must use the basic notification to trigger a separate GET request to fetch the changes.
