The Trade Desk has announced they’re planning to deprecate a couple of sets of dimensions on April 30, 2026. See this announcement about Fold Property deprecations and this announcement for Supply vendor deprecations.
This change will impact the The Trade Desk data source in Supermetrics and requires us to sunset some of the fields we support due to upcoming deprecations.
Deprecated fields
The following fields will be deprecated on April 30, 2026, and will no longer return results days after that date.
Fold
Fold bid factor
Supply vendor
Supply vendor integer ID
However, as Supermetrics stores historical data for The Trade Desk, you’ll still be able to query these fields for dates before April 30, 2026, if we have that historical data available for your advertisers.
To make this clearer, the deprecated fields will be moved to a LEGACY category. We’ll also update their descriptions to indicate that these fields will work for date ranges before April 30, 2026.
For the Supply vendor fields, there are also upcoming replacements, “Selling party name” and “Selling party ID”. We’ll add these fields as soon as The Trade Desk makes them available in our report templates.
We're here for you
