Azure Notification Hubs is implementing a security-focused change set to take effect in October 2024. The key update concerns the expiry duration for the PnsErrorDetailsUri, a generated URI that enables developers to access error details related to their push notifications.

Key Changes

  • Expiry Time Reduction:
    • Current: 10 days
    • New (October 2024): 5 days
  • Scope: This change applies to the PnsErrorDetailsUri returned by Azure Notification Hubs.

Rationale and Benefits

  • Enhanced Security: Shortening the URI expiry window limits the opportunity for unauthorized access in case a URI is accidentally leaked or exposed.
  • Industry Best Practices: Aligns with broader industry trends to minimize the exposure of sensitive or potentially exploitable links.

Implications for Developers

  • Process Updates Needed: Any automated processes or manual workflows that depend on accessing the PnsErrorDetailsUri need to be updated to ensure the information is retrieved within the new 5-day validity period.
  • Documentation: Developers should review and, if necessary, revise their application’s error monitoring and logging procedures to accommodate the expiration change.
  • Notification: This is an advance notice; the change takes effect starting October 2024, giving teams time to adjust.
