Exports endpoints (v3) find and queue log records that match your search criteria for export. Like Logs, exports 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.
Exports endpoints are limited to a maximum of 2 million records each. If more records are required, please make multiple requests with smaller time intervals to pull the necessary data in "batches".
Note: There are substantial differences between v2 and v3 of the Reporting API Log endpoints. Please reference the Migration Guide for more detail.
