Common Conventions
IDs
All entity identifiers are UUIDs (RFC 4122):Timestamps
Timestamp conventions differ between the unified entity endpoints and the policy / task / file endpoints:-
Unified entity endpoints (exposure, event, quote, submission, person, organization) return
createdAt/updatedAtas epoch-second integers inside the entity envelope: -
Policy versions/transactions, tasks, files, and reporting return timestamps such as
transactionTimestamp,createdAt, anddeadlineas ISO 8601 strings in UTC:
Dates
Date-only fields (startDate, endDate, effectiveDate, policyStartDate, policyEndDate) use ISO 8601 date format:
Nullable Fields
Fields that may be absent are typed asT | null. For example, policyId: string | null means the field is always present in the response but may be null.
Pagination
Pagination differs between the unified entity list endpoints and the notes / tasks / files list endpoints.Unified entity list endpoints
The entity list endpoints (exposure, event, quote, submission, person, organization) return:
Query parameters:
Notes, tasks, and files
The notes, tasks, and company-files list endpoints use 1-basedpage / pageSize query parameters (page=1 is the first page). See each endpoint’s reference for its exact response shape.
fieldModelV1Data
Most V1 entities store their custom field data in afieldModelV1Data object. The shape of this object is defined by your company’s field configuration — call the entity’s /configuration endpoint to discover available fields, types, and validation rules.
Keys in fieldModelV1Data are field reference IDs (the stable identifiers you define when configuring fields).
Field Value Types
Date Fields
Date fields infieldModelV1Data are represented as objects with individual components:
API parameters that accept dates directly (such as
policyStartDate, effectiveDate, and other endpoint-level fields) use ISO 8601 date strings ("2026-01-15"), not the component object format. The component format is specific to custom field data inside fieldModelV1Data.Option Set Fields
Option set values are stored as string keys (not labels). Use the/configuration endpoint to map keys to human-readable labels.
Single-select:
oneOf to enumerate valid options:
Configuration Schema
All entity types have a/configuration endpoint that returns a JSON Schema (Draft 2020-12) describing valid field data, wrapped under a top-level fields key:
exposures) within the same fields schema, not returned as a separate top-level key. Calculated values, server-populated fields, and lifecycle fields are excluded.
Schema Format Values
Theformat property indicates the semantic type of a field:
Entities
Entity envelope
The unified entity endpoints (exposure, event, quote, submission, person, organization) all return the same generic envelope. All entity-specific field values live insidefieldModelV1Data, keyed by field referenceId — there is no top-level companyId, policyId, or submissionId.
See the Entities overview for the parametric CRUD surface shared by every entity type (exposures, events, quotes, submissions, persons, organizations), and discover each type’s framework-required fields via its configuration endpoint.
Cross-entity links are expressed as Join fields inside
fieldModelV1Data (for example quoteSubmission on a quote, or eventPolicy on an event), not as separate top-level keys. Calculated and lifecycle fields (e.g. quoteStatus, quoteNumber, submissionNumber) are resolver-populated and cannot be set via the API./configuration response shape is documented under Configuration Schema above.
Directory entities (Persons & Organizations) and custom objects
Persons and Organizations are built-in Directory entities backed by the custom-object model; both use the entity envelope above and thecompany.fmv1_custom_object:* permission family. Configurable relationships between objects use these cardinality values:
Relationship cardinality values: one_to_one, one_to_many, many_to_one, many_to_many
Policy Model
Policies use a transaction-based, temporally-versioned data model. Rather than directly editing policy fields, you submit transactions (new business, endorsement, cancellation, etc.) that produce immutable versions. For a deep dive, see Policy Concepts.Policy Version
Each transaction produces a new policy version containing one or more segments — date ranges where the policy state is identical.Policy Segment
A segment is a date range within the policy term where the policy state is constant. Segments are derived from final state — they are not one-per-transaction.Policy Transaction
Transactions are the immutable record of changes to a policy.
Transaction action values:
NEW_BUSINESS, ENDORSE, CANCEL, REINSTATE, RENEW
