Get the metadata for a configuration element type

get

/rest/{version}/configuration/elementTypes/metadata

Retrieves the metadata (schema) for the specified configuration element type. The metadata enables the client to know the characteristics of each attribute/sub-element that comprises the element type, so the client can self-validate its instance data before submitting a POST or PUT request. Note that the values for certain metadata tags may vary based on the platform or entitlements of the target system, as certain attribute ranges depend on the platform. The metadata returned for a given element type by one system may not be identical to the metadata returned by a different system.

Request

Path Parameters
  • REST API version string.
    Available values: v1.2
Query Parameters
  • Specifies the configuration element type whose metadata is being requested.
Header Parameters
  • The value in the Authorization header must be the string "Bearer {access token}", where {access token} is a valid, unexpired token received in response to a prior /rest/{version}/auth/token request.
