Impression Share Reporting Automation

Hello,

I have been automating our daily ASA reporting via the Apple Search Ads Campaign Management API and have not found a solution for automating the impression share reporting. Is this data available in this API or a in different Apple API?

I looked into scraping the scheduled custom reports but it appears that would violate the terms of service. We are currently manually extracting this data as a custom report for each app every day (weekends and holidays included) and it eats up a lot of time.

Thank you in advance!
