Each transaction represents an immutable change set (new business, endorsement, cancellation, reinstatement, or renewal). Use this endpoint to see the full transaction history of a policy. For detailed per-field deltas, retrieve a single transaction via the Get Policy Transaction endpoint. **Related:** The Bordereau APIs provide a similar transaction-level view across all policies, with the ability to include additional columns for full-term policy fields. Use this endpoint when you need per-field deltas for a single policy; use the Bordereau APIs when you need a flat, reportable listing across policies. **Required permission:** `company.policy:read` ## OpenAPI ````yaml /openapi/generated-external-api.yaml get /api/v1/external/companies/{companyId}/policies/{policyId}/transactions openapi: 3.0.3 info: title: AI Insurance External API description: External API for AI Insurance platform version: 1.0.0 contact: email: support@aiinsurance.io servers: - url: https://app.aiinsurance.io description: Production security: - ApiKeyAuth: [] paths: /api/v1/external/companies/{companyId}/policies/{policyId}/transactions: get: tags: - Field Model Policy Transactions summary: List Policy Transactions description: > Returns a paginated list of all transactions for a policy, ordered by `policyVersion`.
