Boost Insurance Endorsements API

  title: Boost Insurance API
  description: >-
    Partial, factual OpenAPI description of the Boost Insurance Policy Admin
    System (PAS) API. Boost exposes a JSON REST API for the embedded /
    insurance-as-a-service lifecycle: quote, bind/issue, endorse, cancel, and
    claims (FNOL), with outbound webhook notifications. Authentication uses the
    OAuth 2.0 Client Credentials grant; partners exchange a Client ID and Client
    Secret for a bearer token at the authentication endpoint and send it on each
    request. Only endpoints that are publicly documented at the time of writing
    are modeled here. The full request/response schemas, endorsement paths, and
    webhook payloads are published in Boost's partner documentation
    (https://learn.boostinsurance.com/docs and https://docs.boostinsurance.io)
    and are not reproduced here to avoid fabrication.

      description: >-
        Submit FNOL data tied to a Policy. Boost stores the claim against the
        relevant Policy and begins adjudication in-house or via a TPA partner,
        acting as the single source of truth for claim status. Claim updates are
        delivered back to the partner via webhook.
