To ensure the Google Analytics system doesn't receive more data than it can
handle, and to ensure equitable distribution of the system's resources across
users, Google Analytics APIs enforce some limits and quotas on your usage.

The following limits and quotas apply to your overall Google Analytics API usage
(excluding Data API calls) at the Google Cloud project level:

- 50,000 requests per *project* per day.
- 10 queries per second (QPS) per *IP address* .
  - In the [API Console](https://console.cloud.google.com/), there is a similar quota referred to as *Requests per 100 seconds per user*. By default, it is set to 100 requests per 100 seconds per user and can be adjusted to a maximum value of 1,000. But the number of requests to the API is restricted to a maximum of 10 requests per second per user.
  - If your application makes all API requests from a single IP address (for example, on behalf of your users), use the [`userIp`](https://docs.cloud.google.com/apis/docs/system-parameters#definitions) or [`quotaUser`](https://docs.cloud.google.com/apis/docs/system-parameters#definitions) parameter with each request to get full QPS quota for each user.

> [!NOTE]
> **Note:** Daily quotas are refreshed at midnight Pacific Standard Time.

Some APIs have additional restrictions. For details on API-specific limits and
quotas, see the following pages:

- [Data API](https://developers.google.com/analytics/devguides/reporting/data/v1/quotas)

## Errors related to limits and quotas

If the quota of requesting a Google Analytics API is exceeded, the API returns
an error code `403` or `429` and a message that the account has exceeded the
quota. See the [terms of service](https://developers.google.com/terms/)
for more information.

for quota usage, see [Monitoring APIs and capping
