There are two cases when you might need this:
1) You want to upload historical data from your tracker into your SearchAdsHQ account;
2) You see a significant difference in the number of installs and events you see in your SearchAdsHQ account and MMP.
For both of these cases, we will need raw data reports from your MMP (2 CSV files - one for installs, the other one for events). The CSV reports must have the click/tap time column.
Please contact your MMP to obtain these files.
Some comments depending on the MMP you use:
1) AppsFlyer - please see the details on how to download this report here:
How to download raw data report from AppsFlyer
Make sure to apply Apple Search Ads media source filter.
Also, please note that raw data exports from AppsFlyer have a limitation of 200,000 rows. If there are over 200,000 events for the date range you are using, you will need to export several reports selecting a narrower date range.
To check beforehand how many Apple Search Ads events you have for the time period you need a report for, go to the Activity dashboard and apply Apple Search Ads media source filter.
If you do not have access to AppsFlyer raw data reports, please contact AppsFlyer support at firstname.lastname@example.org.
2) Adjust - please contact Adjust support to help you. They usually store only 1-2 weeks of information and provide help to get this data.
