Version: 1.0
Security: bearer, bearer

## Path parameters:

    ID of the Contract

  - `siteId` (string, required)
    Site identifier

## Response 200 fields (application/json):

  - `resourceType` (any, required)
    This is a Contract resource
    Enum: "Contract"

  - `id` (string)
    Any combination of letters, numerals, "-" and ".", with a length limit of 64 characters.  (This might be an integer, an unprefixed OID, UUID or any other identifier pattern that meets these constraints.)  Ids are case-insensitive.

    Example: "https://example.org/resource"

  - `_implicitRules` (object)
