Data obtained by setting the line ID is passed to third-partiesvia:

When setting a line ID in Amazon Ad Server, the data associated with that line ID is passed to third parties through tokens that are automatically added to the placement tag. These tokens are dynamic parameters appended to the ad tag URL, allowing the third party to receive and process the specific data points linked to the line ID. This method ensures that the data is transmitted efficiently and accurately with each ad impression. The "Special instructions section in the exported placement tag.txt file" is for human-readable notes or manual instructions, not for automated data transmission to third parties.
