  description: Record that this document is an API Evangelist assembly of the per-operation OpenAPI documents
    Kissmetrics publishes on each reference page, and that the API is self-declared beta.
  update:
    x-assembled-by: API Evangelist enrichment pipeline
    x-assembled-from: https://support.kissmetrics.io/reference/ (.md twin of each endpoint page)
    x-lifecycle-stage: beta
    x-lifecycle-statement: Kissmetrics states the REST API is "still under heavy development and subject
      to regular changes" that "could result in breaking changes for developers."
- target: $.components.securitySchemes.basicAuth
  description: Kissmetrics publishes two different Basic-auth credential forms. Record both rather than
    choosing one.

    - form: 'API_KEY: (empty password)'
