## What Fibr Sends to the GTM Data Layer

Once connected, Fibr pushes events to the data layer each time a visitor sees a variantt. These events allow you to route important personalization and experiment data into platforms like GA4, Meta Ads, Mixpanel, and more via GTM.

Event Name: **fibr\_track\_event**

| Variable                    | Description                                     |
| --------------------------- | ----------------------------------------------- |
| fibr\_session\_id           | User session information ID                     |
| fibr\_user\_id              | Fibr unique user ID                             |

| fibr\_variation\_name       | Fibr experience name                            |
| fibr\_campaign\_type        | Personalization or Experiment                   |
