# Post Datapoint

`POST /datapoints`

Creates a datapoint in the Isometric system

## Headers

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

## Request body

- CreateDatapointRequest
  - `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.
  - `display_name` string, required
  - `type` 'CONSTANT' | 'STANDARD_PUBLISHED_VALUE' | 'REPORTED' | 'ASSUMPTION' | 'DERIVED', required
  - `quantity` DatapointQuantityInput, required
    - `magnitude` number, required
    - `unit` string, nullable, required
    - `standard_deviation` number, nullable — The standard deviation of the datapoint in the same units as the magnitude. Leave null if the datapoint is not to be included in the uncertainty analysis for the removal.
  - `description` string, required — A free-text description of the datapoint. Must be at most 500 characters long.
  - `source_ids` string[], required
  - `project_id` string, required
  - `measured_at` string, date-time, nullable
  - `uncertainty_justification` string, nullable — Provide an uncertainty justification where required for inputs identified as sensitive in sensitivity analysis.

## Response `200`

Successful Response

- Datapoint
  - `id` string, required
  - `supplier_reference_id` string, nullable, 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.
  - `display_name` string, required
  - `type` 'CONSTANT' | 'STANDARD_PUBLISHED_VALUE' | 'REPORTED' | 'ASSUMPTION' | 'DERIVED', required
  - `quantity` ScalarQuantity, required
    - `magnitude` number, required
    - `unit` string, required
    - `standard_deviation` number, nullable
  - `description` string, nullable, required
  - `source_ids` string[], required
  - `measured_at` string, date-time, nullable, required
  - `project_id` string, nullable, required
  - `locked_status` 'not_locked' | 'locked_library_datapoint' | 'locked_time_series_datapoint' | 'locked_measurement_sample_datapoint' | 'locked_forestry_field_measurement_datapoint' | 'locked_model_output_datapoint' | 'locked_model_input_datapoint' | 'locked_material_datapoint' | 'locked_activity_datapoint' | 'locked_used_in_verified_removal', required — Represents the locked status of a Datapoint. Locked Datapoints cannot be updated: if an updated version of a data input is required then a new Datapoint must be created.
