Starting on October 3, 2025, users will be able to set both the gclid and gbraid fields in their ClickConversion messages when importing to the Google Ads API using the UploadClickConversions method.
Previously, attempting to set both fields resulted in a partial failure error with the code FieldError.VALUE_MUST_BE_UNSET for the gclid field. After this update, the error will be resolved, and users will receive successful import responses.
