| `dateFrom` (query) | string | yes | — | Period start, `YYYY-MM-DD`. |
| `dateTo` (query) | string | yes | — | Period end, `YYYY-MM-DD`. |

## Known specifics

If `complete` is `false`, run the next step by [repeating the POST request with the same period](/docs/entities/crm-tracking/ad-expenses-start). Reading progress alone does not continue building the report.
