`internal_event_id`	String	Unique identifier calculated using xxHash64 of the composite key (`app_token`, `event_type`, `event_name`, `user_id`, `company_id`, `inserted_at`).
`hostname`	String	Hostname where the event took place.

`metadata`	Object	The attributes object varies depending on the `event_type` (see below).

Internal Event ID

The internal_event_id is a unique identifier for each event, calculated using the xxHash64 algorithm on a composite key consisting of the following fields:

app_token
event_type
event_name
user_id
company_id
inserted_at

This identifier provides a deterministic way to uniquely identify events based on their core attributes, which is useful for deduplication and event tracking across systems.

Event Name & Type

The event_name field tracks the name of the event and varies depending on the event_type:

For identify_user, identify_company, session_start, and page_view events: This field will be empty.
For track events: The value will represent the name of the event being passed programmatically or through the button-tracking feature.
For track_feature events: The value will contain the id of the tracked feature tag.
For interaction events:
- The format is {entity_type}:{entity_id}:{entity_interaction_status}
- Example: checklist:2:SEEN, experience:448:DISMISSED, resource_center:1:ENGAGED, experiment:9:SEEN.
When a flow is part of an experiment, both experiment:* and experience:* events are generated to track experiment participation and flow interaction respectively.

Source

The source field indicates where the event was captured. The default value is web-client, but it can vary depending on the source of the event:

web-client: Captured through the web SDK.
backend-http: Captured via HTTP endpoints.
backend-hubspot: Captured through the HubSpot integration.
backend-salesforce: Captured through the Salesforce integration.
backend-segment: Captured through SegmentIO integration.

Attributes Schema

The metadata field varies depending on the event type:

For identify_user, identify_company, and track events: This field will contain custom attributes passed during the event tracking.
For page_view, session_start and track_feature events: This field will be an empty object.
For interaction events: Attributes vary based on the engagement entity type and provide specific interaction details (see below).

Flows in Experiments: When a flow is part of a test experiment, the system generates BOTH experiment:* and experience:* events:

experiment:* events track experiment participation and variant assignment
experience:* events track flow interaction

Experiments (`experiment` events)

When flows are used testing experiments, Userpilot tracks experiment participation through dedicated experiment events. These events capture which variant (test group) a user was assigned to.

Attribute	Type	Description
`interaction_id`	String	Unique ID of the experiment (e.g., `experiment_9`).
`is_dismissed`	String	Indicates whether the experiment interaction was dismissed by the user (`1` for yes, `0` for no).
`never_show_again`	String	Indicates if the user chose to never see this again (`1` for yes, `0` for no).
`status`	String	Current status of the experiment interaction (e.g., `SEEN`, `COMPLETED`, `DISMISSED`).
`total_dismissed`	String	The total number of times the experiment was dismissed by the user.
`variant`	String	The experiment group the user was assigned to. Contains the variant name (A, B, or C).

Variant Values: The variant attribute indicates which test group the user was assigned to. Possible values are “A”, “B”, or “C” depending on the experiment type (Controlled A/B Test, Head-to-Head A/B Test, or Controlled Multivariate Test). For more details on experiment types and how variants are assigned, see the Experiments documentation. Example:

{
  "event_name": "experiment:9:SEEN",
  "attributes": {
    "interaction_id": "experiment_9",
    "is_dismissed": "0",
    "never_show_again": "0",
    "status": "SEEN",
    "total_dismissed": "0",
    "variant": "B"
  }
}

Schema EvolutionUserpilot may add new properties or event types over time. Your data processing pipelines should be designed to handle such changes gracefully (e.g., by not breaking if new, unexpected fields appear).
