Logs endpoints find and return log records that match your search criteria. Logs contain every single ad click, ad impression, app install, app open, app event, app update, app event item and every postback sent on a per account basis.
Logs endpoints are limited to a 5000 record maximum and should not be used for export queries. To export log data, please use the applicable Exports endpoint.
Note: There are substantial differences between v2 and v3 of the Reporting API Log endpoints. Please reference the Migration Guide for more detail.
