# GlideTransientDynamicAttribute - Global

# GlideTransientDynamicAttribute - Global {#ariaid-title1}

Release version: Yokohama  
Updated January 30, 2025  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 7 minutes to read  
The GlideTransientDynamicAttribute API provides access to transient dynamic attribute metadata.

This API provides methods that enable you to get transient dynamic attributes values that are added to a DynamicAttributeStore field and not defined in the Dynamic Attribute \[dynamic_attribute\] table. Transient dynamic attributes are
all handled as String data types and have no sys_id. For more details on dynamic attributes, see [Dynamic schema](https://www.servicenow.com/docs/access?context=dynamic-schema&version=yokohama&pubname=yokohama-platform-administration&ft:locale=en-US). The same methods are also available for dynamic attributes in the [GlideDynamicAttribute - Global](https://servicenow-prod.fluidtopics.net/7A_ss0GHBtbAYZs4KkAZOQ#GlideDynamicAttributeAPI "The GlideDynamicAttribute API provides access to dynamic attribute metadata.") API.

To use this API to create dynamic attributes you must have the dynamic_schema_writer role. To read dynamic data using this API you must have the dynamic_schema_reader role.

Transient dynamic attributes are handled as strings and have no sys_id. {#GTDA-isTransient__ul_trp_nxn_b2c} Note: The Dynamic Attribute \[dynamic_attribute\] table is accessible by navigating to AllDynamic SchemaDynamic Attribute Groups, selecting a group, and selecting the Dynamic Attributes tab. |
