Get your new DSN by creating a project in Decipher

Log in to Decipher with your work email. On the Settings page, choose a project name and click “Create New Project”.
We auto-create a Decipher-only project called “FirstFrontendProject” when your organization registers with Decipher, but that is separate from the Sentry project you’re about to add.
On the following screen, decide where you want to send data. We recommend choosing Decipher only to avoid double charges.
Sending data only to Decipher is the recommended option for many as it:
  • Avoids duplicate charges from multiple providers
  • Provides all the functionality you need in one place
  • Simplifies your monitoring footprint
Decipher will give you a new dsn to copy and paste in the following step.

I want to send data to Decipher and Sentry

Sending data to both Decipher and Sentry requires your existing Sentry DSN and may result in charges from both services.To get your existing Sentry DSN, look for the value of the dsn parameter in your codebase’s call to Sentry.init.
On the next screen, enter your Sentry DSN. Then click “Add this project”.
Your Sentry DSN is only used to compute your Decipher DSN which you’ll use in the next step, and while your Sentry DSN is public, Decipher never stores it.Decipher will create a new project with a dedicated new DSN for you. Using this new DSN will result in data being sent to both Decipher and Sentry.

Update your Sentry initialization to use the new DSN and configuration

Update your instrumentation-client.ts to use your new dsn and make sure replayIntegration and replaysSessionSampleRate are set.Additionally, update sentry.edge.config.ts, and sentry.server.config.ts files to use your new dsn.
On older @sentry/nextjs versions update your sentry.client.config.ts instead of instrumentation-client.ts.
Sentry.init({
  dsn: "YOUR_DSN_FROM_DECIPHER", // Get this at https://app.getdecipher.com/settings
  integrations: [
      Sentry.replayIntegration({
          maskAllText: false,
          blockAllMedia: false,
          maskAllInputs: true,
          networkDetailAllowUrls: [/^.*$/],
      }),
      // You can optionally specify log levels (see further docs)
      Sentry.captureConsoleIntegration(),
      Sentry.browserTracingIntegration(),
  ],
  replaysOnErrorSampleRate: 1.0,
  replaysSessionSampleRate: 1.0,
});
In your codebase, update the line that sets the dsn field of your existing Sentry initialization to use the new value you got from Step 1, and ensure that replayIntegration and replaysSessionSampleRate are set. For example:
    Sentry.init({
    dsn: "YOUR_DSN_FROM_DECIPHER", // Get this at https://app.getdecipher.com/settings
    integrations: [
        Sentry.replayIntegration({
            maskAllText: false,
            blockAllMedia: false,
            maskAllInputs: true,
            networkDetailAllowUrls: [/^.*$/],
        }),
        // You can optionally specify log levels (see further docs)
        Sentry.captureConsoleIntegration(),
        Sentry.browserTracingIntegration(),
    ],
    replaysOnErrorSampleRate: 1.0,
    replaysSessionSampleRate: 1.0,
  });

Identify Users

If you aren’t already doing this, make sure to identify users where user information is available in your application frontend, typically after authentication or login.
// Set user information in Decipher via the Sentry TypeScript SDK
Sentry.setUser({
  "email": "jane.doe@example.com",  // Recommended identifier to set
  "id": "your_internal_unique_identifier", // Optional: use if email not available
  "username": "unique_username", // Optional: use if email not available
  "account": "AcmeCo",  // Recommended: Which account/organization is this user a member of?
  "created_at": "2025-04-01T15:30:00Z", // Recommended: date this user signed up.
  // You can add more user information here as key/value pairs.
});
Once you’re done, simply use your website to validate that Decipher is collecting session replay data (and that Sentry is too, if you selected that option).
