# Overview

## Important information

* Reports are requested and retrieved via **asynchronous endpoints**.
* Most reports are generated at a **daily granularity**, except for the Attributed Transactions report, which is provided at an **hourly granularity**.
* The report date range supports a maximum window of **100 days**, with data retained for up to **3 years**.
* 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,
  * Rate limits for resource-sensitive endpoints may be lower than the standard limit of **250 calls per minute**.
* Report attribution windows and time-zones are fully configurable.
* **Data latency**: please refer to [this section of our Troubleshooting guide](/retail-media/docs/api-troubleshooting-guide#/is-the-issue-that-my-data-is-late) for data latency details.
* 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.
