  description: >-
    OpenAPI description of the BigChange DX REST API (the modern REST interface to
    the BigChange / JobWatch field service and job management platform).


    Grounded: the base URL (https://api.bigchange.com), the path templates, the
    HTTP methods, the Bearer JWT security scheme, and the required Customer-Id
    header are all taken directly from BigChange's own published Swagger/OpenAPI
    documents:
      - https://api.bigchange.com/swagger/v1/swagger.json (BigChange DX, 108 paths)
      - https://api.bigchange.com/swagger/asset-management/v1/swagger.json
      - https://api.bigchange.com/swagger/webhooks/v1/swagger.json


    Modeled: this document is an API Evangelist-authored, representative SUBSET of
    the full published specification. Request and response BODY schemas are
    summarized as generic objects here rather than reproduced field-by-field -
    consult the upstream swagger.json documents above for the complete,
    authoritative request/response models. Every path and method listed below
    exists in the published BigChange spec.
