  title: D&B Authenticate And Match Company
  summary: Obtain a Direct+ token, resolve a candidate record to a D-U-N-S Number, and pull its company information block.
  description: >-
    The canonical Direct+ identity-resolution flow. The workflow exchanges
    client credentials for an OAuth 2.0 bearer token, submits a candidate
    business record to cleanseMatch to obtain a ranked list of D-U-N-S
    matches, and then retrieves the Company Information Data Block for the
    top-ranked candidate. Each step spells out its request inline so the flow
    can be read and executed without opening the underlying OpenAPI
    description.
