Tag API

Last updated June 17th, 2026

The Tag API is a unified device tagging solution for all Knox cloud services. It enables you to assign and manage common tags, which are cross-service device labels that let you filter and organize devices more efficiently across your organization.

Audience

This guide is primarily intended for the following audiences:

  • Enterprise customers who need to categorize and manage devices across multiple Knox cloud services.
  • Managed Service Providers (MSPs) who need to provide tagging capabilities across Knox cloud services to their customers.
  • UEM partners who need to integrate tagging capabilities across Knox cloud services for their enterprise platforms.

Typically, enterprise customers and MSPs integrate using 2-legged authentication, while UEM partners use 3-legged authentication.

Difference between common tags and service tags

Common tags are different from service tags, which are specific to a single Knox cloud service such as Knox Mobile Enrollment or Knox Configure, and can’t be used to filter devices across services.

Common tags and service tags don’t appear in the same list in Knox Admin Portal.

  • Common tags can be managed from the COMMON TAGS tab on the common Devices page.
  • Service tags can be managed from service-specific Devices pages, such as for Knox Manage.

Additional differences are listed in the following table.

Aspect Common tags Service tags
Scope All Knox cloud services Single service only
Filtering Filter devices across multiple services Filter devices within one service
Console access Devices > COMMON TAGS in Knox Admin Portal Service-specific Devices page in Knox Admin Portal
API access Yes (Tag API) No
