Macro	Description
AUCTION_ID	This macro inserts the unique ID of the auction into the URL. This number will be unique each time the macro is loaded. Note: This macro is not supported by Protocol buffer for Authorized Buyers
CACHEBUSTER	String representation of a random unsigned 4 byte integer.
CLICK_URL_ESC	The escaped click URL for the ad. Use this instead of CLICK_URL_UNESC if you need to first pass the value through another server that will then return a redirect.
CLICK_URL_ESC_ESC	Allows two redirects.
CLICK_URL_UNESC	The unescaped click URL for the ad. In the snippet, an escaped version of the third party click URL should directly follow the macro.
SCHEME	Resolves to http: or https:, depending on the inventory type. Only the HTML tag’s text provided to Authorized Buyers will be adapted, so fourth-party calls outside the HTML tag’s text will not be adapted by this macro. This macro is not supported for VAST in-stream video.
SITE	The URL-escaped domain of the content URL.
TZ_OFFSET	Timezone offset.
VERIFICATION	This macro is used to differentiate creative pings that come from the verification process versus serving. Note: For all ad formats, this macro can be appended in the impression_tracking_url, burl, or link assets.
WINNING_PRICE	The encoded impression cost (that is, CPI rather than CPM) in micros of the account currency. For example, a winning CPM of $5 USD corresponds to 5,000,000 micros CPM, or 5,000 micros CPI. The decoded value of WINNING_PRICE in this case would be 5,000. The winning price is specified in CPI.
WINNING_PRICE_ESC	URL-escaped WINNING_PRICE.

AMPHTML Ads

Macro	Description
