Our R&D team encountered the following problems during the development process using the Amazon Advertising API and hoped to get your help. We get a different value of Impressions when we get a report for a specific date on different dates.
A typical scenario is as follows: (The format and content of the parameters of the interface request meet the restrictions listed in the API documents.)
1. Request search term report of 01-JAN-2019 on 03-JAN-2019
2. Request search term report of 01-JAN-2019 on 04-JAN-2019
3. Request search term report of 01-JAN-2019 on 05-JAN-2019
4. Value of Impressions for same search item is different in these reports
I guess Amazon may updates the report every day for a date in history？This may be unreasonable because Impressions should be fixed after that day. Unfortunately, we didn't find any documents related in API.
BTW we used following APIs to get reports:
Could you please give us more information about this?
Thanks a lot for your help.
