aid: whitespace-london url: https://raw.githubusercontent.com/api-evangelist/whitespace-london/refs/heads/main/apis.yml name: Whitespace kind: company description: >- Whitespace Software Limited is a London-based digital placing platform for the Lloyd's and London (re)insurance market, and one of only two electronic placing systems given fully recognised status by Lloyd's. Acquired by Verisk (via Sequel), Whitespace lets brokers and underwriters create, negotiate, quote, firm-order, line, sign and endorse fully digital subscription-market contracts in place of the traditional slip, across property and casualty, specialty, marine, aviation, energy and reinsurance business written in the United Kingdom and internationally. Its API posture is unusually strong for the insurance sector but only half open: the reference documentation is genuinely public and unauthenticated at apidocs.whitespace.co.uk, with a complete OpenAPI 3.0.0 description of 113 endpoints served through Swagger UI at swagger.whitespace.co.uk, yet there is no self-serve signup. Sandbox and production service tokens are issued by Whitespace Support to contracted broker, carrier and vendor organisations, are IP-allowlisted and expire within a year, so the integration surface itself is partner-gated. Whitespace is ACORD-native rather than merely ACORD-aware: it authored the JSON Market Reform Contract (JMRC) standard and donated it to ACORD for incorporation into the Global Reinsurance and Large Commercial data standards, and its Defined Data API returns contract values tagged with an ACORDGPM tagset alongside MRC headings. Event integration is delivered as per-client Azure Service Bus queues rather than webhooks, and no AsyncAPI, GraphQL or public Postman workspace is published. image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg tags: - Insurance - United Kingdom - Reinsurance - Property and Casualty - Insurtech - Broker - Underwriting - Placing Platform - London Market - Lloyd's of London - ACORD - Market Infrastructure created: '2026-07-25' modified: '2026-07-25' specificationVersion: '0.19' apis: - aid: whitespace-london:whitespace-platform-api name: Whitespace Platform API description: >- The Whitespace Platform API is a REST/JSON API over the full London-market subscription placing lifecycle, publicly described by an OpenAPI 3.0.0 document covering 113 endpoints across Risks, Data, Attachments, Documents, Activities, Comments, Labels, Lookup, Endorsements, Lines, Questionnaire, Summary, User and MI Report. It genuinely exposes QUOTE (quoteOnRequest, saveQuoteDetails, getQuoteDetails, showQuoteToBroker, declineQuoteRequest, markAsIndicative, notTakeUpQuotation) and BIND (createBindableQuote, draftToFirmOrder, markAsFirmOrder, writeLine, recordLine, requestWrittenLineSets, acceptWrittenLine, signSets, reSignSets) and ISSUE of the contract document (getExtendedMRC, export/pdf/{riskID}, documents/{docID}), plus post-bind endorsement handling. It does NOT cover FNOL or claims — Whitespace is a placing platform, not a claims system. The embedded Defined Data API (/api/v22.04/data and /api/v23.09/data) returns and verifies structured contract values tagged against MRC headings and an alternative ACORDGPM tagset. Documented servers are the Sandbox, Tess, Beta and Staging environments; production access is arranged separately with Whitespace Support. Authentication is HTTP bearer JWT using a service token issued by Whitespace Support to a contracted organisation, restricted to allowlisted IP addresses and expiring within one year — there is no self-serve key. humanURL: https://apidocs.whitespace.co.uk/ baseURL: https://sandbox.whitespace.co.uk/ tags: - Insurance - Placing - Risks - Quote - Bind - Endorsements - Defined Data - ACORD properties: - type: OpenAPI url: openapi/whitespace-london-platform-openapi.yml - type: APIReference url: https://swagger.whitespace.co.uk/ - type: Documentation url: https://apidocs.whitespace.co.uk/ - type: Documentation url: https://apidocs.whitespace.co.uk/Getting_Started_with_the_Whitespace_API.pdf - type: Documentation url: https://apidocs.whitespace.co.uk/Obtaining_and_Using_a_Service_Token_for_the_API.pdf - type: Documentation url: https://apidocs.whitespace.co.uk/Refresh_Token_Guide_v1.0.pdf - type: Documentation url: https://apidocs.whitespace.co.uk/How_does_API_versioning_work.pdf - type: Documentation url: https://apidocs.whitespace.co.uk/An_Introduction_to_Defined_Data.pdf - type: Documentation url: https://apidocs.whitespace.co.uk/Defined%20Data%20API%20and%20JSON%20Notes.pdf - type: Documentation url: https://apidocs.whitespace.co.uk/JMRC%20ACORD%20Specification%20V0.5%20-%20Defined%20Data.pdf - type: Documentation url: https://apidocs.whitespace.co.uk/Queues_and_the_Whitespace_Platform_v1.2.2.pdf - type: Documentation url: https://apidocs.whitespace.co.uk/Integrating_with_Whitespace_via_Queues_3.1.pdf common: - type: AgenticAccess url: agentic-access/whitespace-london-agentic-access.yml - type: DomainSecurity url: security/whitespace-london-domain-security.yml - type: Authentication url: authentication/whitespace-london-authentication.yml - type: Website url: https://www.whitespace.co.uk/ - type: Documentation url: https://apidocs.whitespace.co.uk/ - type: APIReference url: https://swagger.whitespace.co.uk/ - type: Integration url: https://www.whitespace.co.uk/integration/ - type: Support url: https://www.whitespace.co.uk/support-training/ - type: Blog url: https://www.whitespace.co.uk/news-events/ - type: ContactUs url: https://www.whitespace.co.uk/contact-us/ - type: TermsOfService url: https://www.whitespace.co.uk/interchange-agreement - type: PrivacyPolicy url: https://www.whitespace.co.uk/privacy/ - type: LinkedIn url: https://www.linkedin.com/company/whitespace-software-limited - type: Twitter url: https://twitter.com/WhitespaceEC1 - type: ParentCompany url: https://www.verisk.com - type: Packages url: packages/whitespace-london-packages.yml - type: CLI url: cli/whitespace-london-cli.yml - type: Conventions url: conventions/whitespace-london-conventions.yml - type: ErrorCatalog url: errors/whitespace-london-problem-types.yml - type: Lifecycle url: lifecycle/whitespace-london-lifecycle.yml - type: Deprecation url: https://apidocs.whitespace.co.uk/How_does_API_versioning_work.pdf - type: ChangeLog url: changelog/whitespace-london-changelog.yml - type: ChangeLog url: https://www.whitespace.co.uk/release-notes - type: Sandbox url: sandbox/whitespace-london-sandbox.yml - type: Conformance url: conformance/whitespace-london-conformance.yml - type: DataModel url: data-model/whitespace-london-data-model.yml - type: AsyncAPI url: asyncapi/whitespace-london-queues-asyncapi.yml - type: AgentSkill url: skills/_index.yml - type: MCPServer url: mcp/whitespace-london-mcp.yml - type: LLMsTxt url: llms/whitespace-london-llms.txt - type: Overlay url: overlays/whitespace-london-platform-overlay.yaml - type: DeveloperPortal url: https://apidocs.whitespace.co.uk/ - type: GettingStarted url: https://apidocs.whitespace.co.uk/Getting_Started_with_the_Whitespace_API.pdf - type: GitHubOrganization url: https://github.com/whitespace-software - type: Login url: https://www.whitespaceplatform.com/ maintainers: - FN: Kin Lane email: kin@apievangelist.com
