# Set Output Name for Activation Attributes

When you configure an activation in Data 360, you can customize the attribute names in your output file or stream. Custom attribute names help match the naming conventions required by your activation target. Use the output namefield ( preferred name) to define these values.

By default, the Output Name field shows the API name of the attribute with system prefixes and suffixes removed. To override the default API name, enter a custom preferred value in the Output Name field. Data 360 uses this value as the column header or field name in the activation output.

The output names must be unique across all attributes in the activation, including attributes from different data model objects (DMOs). Output names can contain only alphanumeric characters.
