Hello,
Currently, the Top of Page bid (low range, high range) is currently not supported through the API. You will be able to use the
TargetingIdeaService by selecting the
requestAttributeType as AVERAGE_CPC. These stats will be similar to the stats in the old UI. Please take a look at
this guide on how the API results
map with the Keyword Planner tool.
Let me know if you have any other question.
Regards,
Bharani, AdWords API Team
