# Network logs

Gleap allows you to monitor network requests for a better understanding of what's happening within your app.

### Configure network logs

Managed .NET has **no global HTTP interception**, so — unlike the native SDKs — only traffic routed through a Gleap handler is captured. Add the handler returned by `CreateNetworkLoggingHandler()` to the `HttpClient` instances you want to monitor. `backend` is the `ManagedBackend` returned by the platform attach call (for Windows: `GleapMessenger.Backend`).

```csharp theme={null}
using var http = new HttpClient(backend.CreateNetworkLoggingHandler());

await http.GetAsync("https://example.com");
```

You can toggle capture at runtime:

```csharp theme={null}
Gleap.StartNetworkLogging();
Gleap.StopNetworkLogging();
```

## Filtering network logs

Gleap allows you to strip specific key/value pairs from network logs. This lets you remove sensitive data like `tokens`, `passwords` or `usernames` before anything leaves the client.

Log in to the [Gleap dashboard](https://app.gleap.io), open the visual widget configurator, and enable the `network log filters` option (in the advanced options tab). Every key you add is loaded with the widget configuration; before sending a feedback item the SDK strips all matching key/value pairs from the request headers, JSON header payloads and JSON response bodies.

### Set filter with code

```csharp theme={null}
// Manually set the network log filters.
Gleap.SetNetworkLogPropsToIgnore(new[] { "api-key", "user.password" });
```

## Blacklisting URLs

If a network request matches an entry in the blacklist, it won't be included in the network logs. You can maintain the list in the dashboard under **Developer options**, or set it by code.

```csharp theme={null}
// Manually set the network log blacklist.
Gleap.SetNetworkLogsBlacklist(new[] { "https://api.gleap.io" });
```
