Using Tealium Functions for Acxiom Identity Resolution | Industries |Preview of Tealium Docs

We recommend using a visitor function to capture the data from Acxiom. For more information on visitor functions, see Event and Visitor Functions.

The visitor function does the following:

Requests the additional data from Acxiom.
Sends an event containing the additional data and tealium_visitor_id to Tealium Collect.

The EventStream attributes and visitor attributes are enriched by the event sent from the function.

Prerequisites

Tealium EventSteam and Tealium Functions.
The Tealium Collect API as a data source.
Visitor attributes to store the additional information.
An event specification titled acxiom_function_event with the attributes required to enrich the visitor attributes.
An enrichment to set the visitor attributes to the value of the event attributes.

The function works best when the Acxiom Real Tag tag is installed. This identifier increases the confidence rating for the visitor.

Creating a function to process the event

To create the function:

Navigate to Functions.
Click Add Function.
Enter a name for the function.
Enter notes to describe the function.
Select the Processed Event trigger.
Select the event feed for the trigger.
Click Continue.
Enter the sample code below into the Code box.
Customize the code as necessary for your configuration.
Save the function.

You can test the function with the Test feature and a tool such as Postman API Workbench.

For more information on creating a function, see Managing Functions.

Example function code

The test example function included below attempts to match a visitor profile based off of the attributes you send to it:

Attribute	Description
`acxiom_function_event`	Event Spec name
`realId`	Acxiom rTag
`address`	User’s address
`phone`	User’s phone number
`email`	User’s email address
`fullName`	User’s full name

The function returns any additional user data for profile enrichment.

This code is currently in beta.
