The
AD_PERFORMANCE_REPORT and
KEYWORDS_PERFORMANCE_REPORT won't show you your URLs with parameter values substituted, since the
FinalUrls fields on those reports simply reflect the current state of the final URLs on ads or keywords, with the
ValueTrack and custom parameters shown in brackets. However, the
EffectiveFinalUrl field on the
new FINAL_URL_REPORT should provide this info.
Please give that a try and let me know if that solution doesn't work for you.
