## Rate Limits

The DSP Reporting API is rate limited per the following quota limits:

| **Type** | **POST** | **GET** | **Description** |
| --- | --- | --- | --- |
| Request limit per Min | 20 | 60 | Max number of reporting Requests by Method Type per User per Minute. |
| Request limit per Hour | 100 | 300 | Max number of reporting Requests by Method Type per User per Hour. |
| Request limit per Day | 800 | 12,000 | Max number of reporting Requests by Method Type per User per Day. Limit is for a 24 hour interval starting from the first request from any user. |

If in your normal processing, you hit one of these limits, please reach out to your Account Manager or Product Support.

They can work with you to optimize your requests. If optimizing is not successful in reducing the number of requests, they can request a small increase to the limits.

## Recent Data Limitations

In order to deliver these large reports quickly, the platform must periodically preprocess and consolidate campaign data. Consequently, recent campaign data, data collected from events occurring in the previous six hours may or may not be available in reports.

If you need up-to-the-minute reporting data, you can always run reports in the Yahoo DSP console. To learn more, refer to [Insights](https://sso.admanagerplus.yahoo.com/app/insights).
