# Post Component

`POST /components`

Creates a component in the Isometric system

## Headers

- `x-client-secret` string, required — A secret token identifying the client connecting to the API

## Request body

- CreateComponentRequest
  - `supplier_reference_id` string, required — A string that must be unique for all resources created by a specific supplier. It can be used by a client to identify the correct objects in their system.
  - `project_id` string, required — The project in which to create the component
  - `component_blueprint_key` string, required — The key of the blueprint which we are deriving this component from.
  - `display_name` string, required
  - `description` string, nullable — A description of the component. Must be at most 2000 characters long.
  - `activity_completed_at` string, date-time, required — The date at which the physical activity related to this component started
  - `activity_started_at` string, date-time, required — The date by which the physical activity related to this component finished
  - `inputs` union[], required — A list of component inputs. This must match the list of inputs on the component blueprint. See the component-blueprints endpoint.
    - union
      - CreateComponentListInput
        - `__typename` 'CreateComponentListInput' — Contains the name of the model (formally, OpenAPI Schema Object). Used to determine the type of data, for example when two different types are unioned.
        - `input_key` string, required — An input key from the component blueprint.
        - `datapoint_ids` string[], required — The Isometric IDs of the datapoints that will be used to populate the value of this input
      - CreateComponentScalarInput
        - `__typename` 'CreateComponentScalarInput' — Contains the name of the model (formally, OpenAPI Schema Object). Used to determine the type of data, for example when two different types are unioned.
        - `input_key` string, required — An input key from the component blueprint.
        - `datapoint_id` string, required — The Isometric ID of the datapoint that will be used to populate the value of this input

MANUAL - No automatic amortization. All GHG Statement and GHG entry attributions are performed manually. CUSTOM_TIME_PERIOD - Automatic amortization ensuring full amortization by a specified target date. ESTIMATED_PROJECT_LIFETIME - Automatic amortization ensuring full amortization over the project's estimated lifetime.
