# Monitor the integration status

> When you are building a new integration or making changes to an existing one, you may want to monitor the requests sent via the Integration API.

> For the complete documentation index, see [llms.txt](https://docs.talon.one/llms.txt).

## Monitor Application health

Application health is measured by the recency of API requests, and the
percentage of requests that failed (returned a `4xx` status code, for example, `400` or `404`).

To display the **Health** section, open your Application, and select <Settings className="icon" />
**Settings** > **Integration API Keys**.

The health status can be one of the following:

- `NONE`: During the last five minutes, the Application hasn't recorded any Integration API requests.
- `OK`: The Application received only successful API requests in the last five minutes.
- `WARNING`: The Application received at least one failed request in the last 50 minutes.
- `ERROR`: More than 50% of received requests failed.
- `CRITICAL`: All received requests failed.

## Monitor API requests

To see the Integration API requests received by your Application, use the [Integration API logs](/docs/product/account/logs/integration-api-logs.md).
