You can specify attributes in the audience data that can be used to describe individuals in the audience data. The values of the attributes that you define here do not typically relate to only one individual in the audience data and therefore cannot be used as an identifier.

Specifying audience attributes is optional, but you can define or more attributes that describe at least some of the individuals that are present in an audience. In general, the more descriptive attributes that you can provide that more useful your endpoint becomes to Acoustic Exchange users who look to combine information from various endpoints to address their business objectives.

If you specify audience attributes, you must provide an attribute name and specify the data type of the attribute value.

Because audience attributes can sometimes reveal personally sensitive information, Acoustic Exchange supports various hashing algorithms to obscure the data.
