openapi: 3.0.3 info: title: D&B Direct+ Authentication Multi-Process API description: D&B Direct+ is Dun & Bradstreet's RESTful API platform that exposes the D&B Data Cloud — more than 500 million companies worldwide — for identity resolution, search, enrichment, multi-process (match plus enrich), batch processing, change monitoring, and historical research. All endpoints return JSON, are versioned in the URI path, and require an OAuth 2.0 bearer token obtained from the /v3/token endpoint via client-credentials grant. This profile is an OpenAPI sketch of the public surface based on Dun & Bradstreet's published Direct+ documentation; the canonical operation definitions live behind the gated developer portal at https://directplus.documentation.dnb.com/. version: '3.0' contact: name: D&B Direct+ Support url: https://service.dnb.com/ termsOfService: https://www.dnb.com/utility-pages/terms-of-use.html license: name: Proprietary url: https://www.dnb.com/utility-pages/terms-of-use.html servers: - url: https://plus.dnb.com description: Production tags: - name: Multi-Process description: Combined match plus enrich in a single call. paths: /v1/multiProcess: post: tags: - Multi-Process summary: Match Plus Enrich In One Call description: 'Combine Identity Resolution and Enrich in a single request: supply a candidate input record and the desired data blocks; Direct+ returns the resolved D-U-N-S match together with all requested enrichment payloads.' operationId: multiProcessMatchAndEnrich security: - bearerAuth: [] requestBody: required: true content: application/json: schema: $ref: '#/components/schemas/MultiProcessRequest' responses: '200': description: Resolved match plus enrichment payloads. content: application/json: schema: $ref: '#/components/schemas/MultiProcessResponse' '401': $ref: '#/components/responses/Unauthorized' components: schemas: OrganizationSummary: type: object properties: duns: type: string pattern: ^[0-9]{9}$ primaryName: type: string primaryAddress: $ref: '#/components/schemas/Address' countryISOAlpha2Code: type: string telephone: type: array items: type: object properties: telephoneNumber: type: string registrationNumbers: type: array items: type: object properties: registrationNumber: type: string typeDescription: type: string MultiProcessRequest: type: object required: - inquiryDetail - blockIDs properties: inquiryDetail: type: object properties: name: type: string countryISOAlpha2Code: type: string address: $ref: '#/components/schemas/Address' blockIDs: type: array items: type: string Error: type: object properties: transactionDetail: $ref: '#/components/schemas/TransactionDetail' error: type: object properties: errorMessage: type: string errorCode: type: string errorDetails: type: array items: type: object MultiProcessResponse: type: object properties: transactionDetail: $ref: '#/components/schemas/TransactionDetail' matchCandidates: type: array items: $ref: '#/components/schemas/MatchCandidate' organization: type: object description: Resolved enrichment payload for the top-ranked match.
