These are added to URLs to pass relevant campaign, placement, ad ID details to a third-party measurement system.

Tokens are small pieces of information appended to URLs (often as query parameters) to transmit specific data points, such as campaign ID, placement ID, or ad ID, to third-party measurement systems. This allows for detailed tracking and attribution of ad performance. Aggregated reports provide summarized data after collection, not the mechanism for passing individual data points. API integrations facilitate direct communication between systems but are a broader method of data exchange, not the specific URL-based mechanism for passing tracking parameters.
