GET/groups/{group_id}/pipeline-components/{component_id}

Read one component, its draft body and its published versions

get_group_pipeline_component
  • pipeline:read
    A token needs the pipeline:read scope: View pipeline runs and definitionsGranted by read_api, read_repository, write_api, write_repository.Every operation this scope unlocks

Returns the component with its draft body, advisory diagnostics for that draft, and every version it has published, newest first. A component can be read from the scope that owns it and from any scope beneath it; anywhere else it is not found. Anyone who can read the pipelines here may call it.

Parameters

Path
  • group_idGroupId (string · uuid)The group's id
  • component_idComponentId (string · uuid)The component's id

Responses

200The component, its draft body and every version it has published, newest firstapplication/json
  • bodyComponentBodyThe draft: what the next published version will contain.
    • The ComponentBody schema
    • component_instancesarray of NestedComponentInstanceoptionalOther components this component uses. Always empty in a published version, where they have already been expanded into steps.
      • The NestedComponentInstance schema
      • component_idComponentId (string · uuid)
      • idNodeId (string)
      • namestring
      • versionComponentVersionRef (string)
      • component_refstring or nulloptional
      • paramsobjectoptional
      • stage_mapobjectoptionalBinds every slot the referenced component declares to a slot of the containing body.
    • edgesarray of EdgeoptionalConnections between the component's own steps; both ends must be steps of this component.
      • The Edge schema
      • idEdgeId (string)
      • source_node_idNodeId (string)
      • target_node_idNodeId (string)
      • source_portPortName (string) or nulloptionalAbsent on a dependency-only edge.
      • target_portPortName (string) or nulloptionalAbsent on a dependency-only edge.
    • inputsarray of ComponentInputPortoptional
    • nodesarray of ComponentNodeoptional
      • The ComponentNode schema
      • nodeNode
      • stage_slotStageSlot (string)Which of the component's stage slots this step is placed in.
      • param_slotsComponentNodeParamsoptionalStep fields whose values come from the component's parameters rather than from the step.
    • outputsarray of ComponentOutputPortoptional
    • parametersarray of ComponentParameteroptional
      • The ComponentParameter schema
      • nameComponentParamName (string)
      • param_typeComponentParamTypestringnumberbooleanobjectarrayThe JSON shape a parameter's value must have.
      • allowed_valuesarray of object or nulloptionalThe only values this parameter accepts. Absent means any value of its type. On a published parameter, adding this list or removing a value from it is a major version change; adding a value is a minor one.
      • defaultobjectoptional
      • descriptionstring or nulloptional
      • requiredbooleanoptionalWhether a pipeline using the component must supply a value. A required parameter cannot have a default.
    • stage_slotsarray of StageSlot (string)optionalThe positions the component's steps occupy, in order. A pipeline using the component maps each slot to one of its own stages.
  • created_atstring
  • created_byActorSummary
  • idComponentId (string · uuid)
  • nameComponentName (string)
  • scopeScopeRef
  • updated_atstring
  • version_countinteger · int640–∞
  • descriptionstring or nulloptional
  • diagnosticsValidationSummary or nulloptionalProblems found in the draft. A draft is saved even when it is invalid.
    • The ValidationSummary schema
    • validboolean
    • violationsarray of ValidationViolation
    • warningsarray of ValidationWarningoptionalThings worth knowing that do not make the definition invalid, such as a deprecated component version. A violation stops a published definition from being saved; a warning never does. Left out when there are none.
  • latest_versionComponentVersion (string) or nulloptional
  • versionsarray of ComponentVersionSummaryoptionalPublished versions, newest first. Present on a single-component read.
    • The ComponentVersionSummary schema
    • capability_requirementsarray of CapabilityId (string)The provider capabilities the version's steps use.
    • contract_digeststringA SHA-256 fingerprint, in hex, of what a pipeline using the version must satisfy: its parameters, its ports and the variables it reads. It changes only when that contract does.
    • depthinteger · int320–∞How many levels of components the version spans: 1 when it uses no other component.
    • expanded_node_countinteger · int320–∞How many steps the version expands into.
    • lifecycle_stateComponentLifecycleStateactivedeprecatedsunsetWhere a published version sits in its retirement. A deprecated version still resolves for an exact reference and still runs, but no floating reference selects it — which is what makes deprecating the safe way to retire one. A sunset version refuses to resolve at all, exact reference included.
    • published_atstring
    • published_byActorSummary
    • variable_requirementsarray of EnvironmentVariableName (string)The variables the version's steps read from the pipeline that uses it. Each must be declared on the environment those steps run in, or on a group or repository above the pipeline, or a run is refused when it starts.
    • versionComponentVersion (string)
    • changelogstring or nulloptional

  • errorErrorBody
    • The ErrorBody schema
    • codestringThe coarse category, tied to the status: NOT_FOUND, CONFLICT, INSUFFICIENT_SCOPE. Every error has one; the API reference's error catalogue lists them all.

    • fieldstring or nulloptionalOn a 400 that refused one field's value, the field, as its JSON path: email, items[0].name. Put the message under that input. Absent on every other error.
    • reasonstring or nulloptionalThe specific code, when the error has one: LAST_ORGANIZATION_OWNER, BRANCH_PROTECTED. The message starts with it too. Match on this when it is present, and on code otherwise.
