Recording Custom User Traits

If you want to view any other custom user traits in the Marketing Campaigns list dashboard, you must create a Custom Field inside Marketing Campaigns’s UI of the traits in your identify calls. Note that you do not need to map all user.traits you are sending inside Marketing Campaigns. You only need to create Custom Fields of the traits you want to see in your list view.

Custom Fields

To send custom fields/user traits to Marketing Campaigns you need to create the field first in Marketing Campaigns for each trait you want sent to Marketing Campaigns. Then when you call identify with keys that match those traits they will appear in your Marketing Campaigns list.

For any other custom traits just add a Custom Field inside of SendGrid with a tag that matches the key you are using in your identify call.

Recording userId

To record a Segment userId in SendGrid, you must pass the userID as a trait on your identify() calls. SendGrid does not automatically map the Segment userID to any Marketing Campaigns properties.

SendGrid API Key

The Upsert Contact Action requires the SendGrid API Key to have the following scopes:

  • Marketing: full
