## Before Starting

The following information is important to know regarding Demand Side Analytics.

### Asynchronous Workflow

Reports are requested and retrieved using **asynchronous endpoints**.

### Granularity

Most reports are generated at a **daily granularity**, except for the Attributed Transactions report, which is provided at an **hourly granularity**.

### Report Date Range

The report date range supports a maximum window of **100 days** for campaign and line-item reports, and **31 days** for account-level reports, with data retained for up to **3 years**.

### Report Row Limits

Reports are limited to **100,000 rows**. If a report reaches this limit, the data may be incomplete due to truncation. To avoid this, consider reviewing the following parameters for bulk requests:

- Number of campaign or line item IDs
- Start and end date range
- Report type

### Report Attribution

- Report attribution windows and time-zones are fully configurable.
- Data is processed and batched **hourly**. Same-day data may be partially available.
- While reports with an end date of today or yesterday are cached for 1 hour, reports with an end date older than yesterday are cached for **24 hours.**
- The exact expiration time is provided in the `expiresAt` field of the /status response.

### Rate Limits

You can find more details about rate limits on [this page](https://developers.criteo.com/criteo-apis/docs/rate-limits).

- **Initial attribution data** is available within **7–9 hours** of the sale.
- **Final attribution data** is processed and posted within **74 hours** after the sale.
