  + https://developer.greencheckverified.com/guides/integration-overview (published token response
  showing the scope array returned to a service provider)
docs: https://developer.greencheckverified.com/guides/integration-overview
summary: >-
  Green Check Access is an OAuth 2.0 client-credentials API whose access token carries a scope array.
  The OpenAPI declares scopes per operation under the `access_auth` scheme; ten distinct scopes appear
  across the 49 operations. Note the spec models the scheme as `apiKey` in the Authorization header
  rather than as an oauth2 securityScheme, so the automated oauth2 derivation finds nothing — the
  scopes below were read out of the per-operation security blocks by hand and cross-checked against
  the docs.

scopes:
  - name: service-provider:read
    operations: 12
    description: Read the calling service provider's own organization record, its connected CRBs, POS credential schemas, license search, onboarding templates and CRB profiles.
  - name: service-provider:write
    operations: 1
    description: Create a CRB under the calling service provider (POST /service-providers/{sp_id}/crbs).
  - name: point-of-sale:read
    operations: 22
    description: Read POS-sourced operational data for a connected CRB — sales, products, inventory, inventory locations, customers and documents.
  - name: point-of-sale:write
    operations: 1
    description: Applied to the CRB customer-search operation (GET .../customers-search). Note this is a read in HTTP terms but is scoped as a write in the contract.
  - name: crb:read
    operations: 3
    description: Read a CRB directly by crb_id, and list/read that CRB's documents, on the CRB-scoped (non service-provider) routes.
  - name: ein:read
    operations: 1
    description: Search existing CRBs by EIN (GET /service-providers/{sp_id}/ein-search).
  - name: connect-crb-to-sp:write
    operations: 1
    description: Connect an existing CRB to the calling service provider by CRB_ID.
  - name: create-crb-api-key:write
    operations: 1
    description: Generate Green Check Access credentials on behalf of a CRB so the service provider can operate that CRB's document-management calls.
  - name: trace
    operations: 6
    description: Use the Trace proxy pass-through to state contracted track-and-trace systems (all HTTP methods on /trace/*).
  - name: admin
    operations: 48
    description: >-
      Present as an alternative on every operation except the token endpoint. A token carrying `admin`
      satisfies the requirement on all 48 secured operations, including every Trace write. This is the
      one scope an integrator should never accept if a narrower one will do.
published_scope_example:
  source: https://developer.greencheckverified.com/guides/integration-overview
  scope: [ServiceProviderRead, ServiceProviderWrite]
  note: >-
    The docs' example token response shows human-readable scope names (ServiceProviderRead /
    ServiceProviderWrite) that do NOT match the colon-delimited scope strings in the OpenAPI
    (service-provider:read / service-provider:write). Recorded verbatim from both sources rather than
    reconciled — an integrator should expect one naming or the other and confirm with Green Check
    which the issued token actually carries.
