# Tags (with Sentry)

> Add custom tags to your sessions for better filtering and organization. Tags can also be used to track events from other platforms like Segment.

## Overview of Tags

Tags in Decipher allow you to add custom metadata to your sessions, making it easier to filter, search, and organize session replays. By using the `setExtras` method from the Sentry SDK, you can attach key-value pairs to your sessions that will be available for filtering within Decipher.

These key-values can be arbitrary and you will be able to filter replays by these tags in Decipher.

## Why Tags?

* **Targeted Analysis**: Focus on specific user segments or feature implementations
* **Issue Prioritization**: Quickly identify which segments are most affected by issues
* **Customer Support**: Filter sessions by company to assist specific customers
* **Feature Adoption**: Track which segments are using new features

## Adding Tags to Your Sessions

To add custom tags to your sessions, use the `setExtras` method from the Sentry SDK. This method accepts an object containing key-value pairs that will be attached to the current session.

```javascript theme={null}
import * as Sentry from "@sentry/browser";

// Add custom tags to this session (example tags)
Sentry.setExtras({
  feature_enabled: true,
  customer_tier: "premium",
  experiment_group: "A",
});
```

## Integrating with Segment

If you're using [Segment](https://segment.com) for analytics, you can easily integrate it with Decipher to enrich your session data:

```javascript theme={null}
import * as Sentry from "@sentry/browser";
import { analytics } from "@segment/analytics-next";

// Initialize Segment
analytics.load("YOUR_SEGMENT_WRITE_KEY");

// Track an event with Segment and add the same properties to Sentry
function trackWithSegmentAndSentry(eventName, properties) {
  // Track with Segment
  analytics.track(eventName, properties);

  // Add the same properties as tags in Sentry
  // Include the event name as `segment_event_name`
  // to ensure it's available in Decipher
  Sentry.setExtras({
    segment_event_name: eventName,
    ...properties,
  });
}

// Example usage
trackWithSegmentAndSentry("Feature Used", {
  featureName: "dashboard",
  userType: "admin",
  companySize: "enterprise",
});
```

## Best Practices

* **Avoid sensitive data**: Don't include PII or sensitive information in tags
* **Combine with user identification**: Use tags alongside `setUser` for the most comprehensive session data

That's it! With just a few lines of code, you can add powerful filtering capabilities to your use of Decipher.
