An **event** is a claim or incident reported against a [policy](/entities/policy). When something happens to an insured risk — a loss, a claim, an incident — it's recorded as an event tied to the policy it falls under. Event detail page showing status Open, coverage type General Liability, an event ID, a description, and the multiple exposures the event references. Working in the app? See the [Events feature reference](/app/features/events) for the list view, detail tabs, and actions. ## How its data works An event is a set of **fields configured per company**, and events are the most open-ended of the entities: beyond the platform's required fields, **you can add and edit any fields you like, with essentially no constraints**. The platform requires a type, a status, an auto-assigned reference id, and a name (which it derives for you), and your configuration defines everything else — dates, amounts, coverage details, and any custom fields. An event's status starts *open* by default, and its name is generated by the platform from the exposures and claimant involved. In the app, the **Actions** menu at the top right of an event collects the lifecycle operations — closing and re-opening, converting between claim and incident, renaming, generating forms, and deleting. See [Event actions](/app/features/event-actions). ## What it connects to | Connects to | How | | ------------------------------- | -------------------------------------------------------------------------------------------------------- | | [Policy](/entities/policy) | Each event is reported against **one** policy. A policy can have many events. | | [Exposures](/entities/exposure) | An event references the **exposures** it touches (many-to-many) — a single incident can involve several. | ## Files, Notes & Contacts Events support all three shared tabs: **upload files**, record **notes**, and attach **contacts** (people from the directory, such as the claimant or adjuster). **API.** Managed through the unified entity CRUD surface as `event`. See the [Entities API overview](/api-reference/entities/overview). **Framework-required fields.** | Field | Notes | | --------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | `eventName` | Derived by the platform (`DERIVE_EVENT_NAME(referencingExposures, claimant)`). | | `eventType` | Option Set (e.g. Claim / Incident). | | `eventStatus` | Defaults to `open`. Settable when the event is created (a historical import can load an already-closed claim), but changing it afterwards goes through the close / re-open actions rather than a field update — they move the status and append to the log together. | | `eventReferenceId` | Auto-generated. | | `eventCoverageType` | Option Set. | | `eventDate`, `reportDate`, `closedDate` | Dates. | | `eventOpenCloseHistory` | List of Objects — the event's open / close / re-open log. Each entry carries `actionTakenDate`, `effectiveOnDate` and `action` (`open`, `close` or `reopen`). The platform appends an entry when an event is created, closed or re-opened; it stays writable so a historical import can supply a claim's full log. | | `openedOn` | Date, read-only — the effective date of the first `open` entry in the log. | | `reopenedOn` | Date, read-only — the effective date of the most recent `reopen` entry; empty when the event has never been re-opened. | | `previousClosedOn` | Date, read-only — the effective date of the last `close` that preceded that re-open; empty when the event has never been re-opened. | | `isReopened` | Boolean, read-only — whether the event has ever been re-opened. Empty (rather than `false`) on an event that has not been written since these fields were added. | | `referencingPolicy` | The policy this event is reported against (**singular**; reverse-read). | | `referencingExposures` | Exposures this event touches (tenant-defined expression). | | `contacts` | People linked as contacts (join to Person). | Additional fields are configured per company; discover them via the `/entities/event/configuration` endpoint.
