Connect to Viant

Go to the Destinations overview page and click the Add destination button. Select Viant and click Continue. You can then authenticate Hightouch to Viant.

For the Authentication method, select Log in to Viant and log into your Viant account. Once successful, you will be redirected back to Hightouch to enter a descriptive name for your destination and complete setup.

Sync configuration

Once you've set up your Viant destination and have a model to pull data from, you can set up your sync configuration to begin syncing data. Go to the Syncs overview page and click the Add sync button to begin. Then, select the relevant model and the Viant destination you want to sync to.

Syncing audiences

Sync data from any source to Viant audiences.

Record matching

You can match rows from your model to audiences in Viant on any column in your model and any field in Viant. Ensure the data types of the model column and Viant field you select match. Refer to the record matching docs for more information.

Accepted ID formats

Each Viant Audience Segment has a specified dataType that gets set when creating a new segment for the first time. If using an exsiting segment, the label will show what dataType the segment has. Viant supports the following dataTypes:

  • Email (sha_256)
  • Address (sha_256)
  • IP address
  • Cookie
  • Mobile ID

If using Email (sha_256) or Address (sha_256), Hightouch can auto apply hashing if selected. To use Address (sha_256), please refer to Viant's docs on preparing your user data for formatting and standardizing your physical addresses before hashing.

Field mapping

Hightouch lets you sync audience fields via field mapping. You can map data from any of your model columns to the default audience fields. Ensure your model's columns have the same data types as the fields you want to sync to.

Split retries

Viant counts all audiences in a batch as rejected if the request contains a single invalid audience. To pinpoint which audiences are getting rejected with which errors and reduce the number of valid audiences that get retried, you can enable split retries.

Syncing conversion events

Send online and offline conversion event data to Viant's DSP (Adelphic) platform.

To ensure syncs send each event, your event model must use a truly unique primary key. See the events syncs documentation for more information.

Account configuration

User identifiers

  • Email (SHA256)hashed_email
  • Address (SHA256)hashed_physical_address
  • IP address

  • Mobile ID (IDFA/GAID)

If using Email (SHA256) or Address (SHA256), Hightouch can auto-apply SHA256 hashing if selected. To use Address (SHA256), refer to Viant's docs on preparing your user data for formatting and standardizing your physical addresses before hashing.
