Authorizations

​
Authorization
string
header
required

API key passed as a Bearer token. Keys are scoped to one organisation and a set of permitted sites. Two keys per scope (primary + secondary) are issued to support zero-downtime rotation.

Authorization: Bearer <api-key>

Path Parameters

​
id
string
required

Cula-assigned resource ID in TypeID format (e.g. stp_01kqzcjrpxf27tge33jwvjhkff). Alternatively, pass your external ID prefixed with ext- (e.g. ext-MY-STEP-001). The ext- prefix is unambiguous because TypeIDs use _ separators and never start with ext-.

​
config_id
string
required

Root data point config ID. Discover available config IDs through the parent resource's config version endpoint.

Body

application/json
​
input_value
required

The value of a data point. The accepted type depends on the data point config's type:

Config typeValue typeExample
short_text, long_textstring"George"
multi_textstring[]["wind", "solar"]
number, percentage, durationnumber15.7
booleanbooleantrue
amountAmount object{ "value": 840.71, "unit": "bushel" }
timestampstring (ISO-8601)"2026-03-15T09:00:00Z"
material_id, container_type_idResourceRef{ "id": "mat_..." } or { "external_id": "corn-no2" }

Response

Data point updated. Returns the full periodic emission log. Recalculation triggered.

A periodic emission log as returned in responses. After creation, the server triggers a background emission calculation. The status field reflects the calculation state and emissions_in_kg_co2e contains the result once calculation completes.

​
id
string
required

Cula-assigned TypeID.

Example:

"eml_01kqzcjrpyf27tgebyhvvmf20z"

​
config_id
string
required

Root emission log config ID.

Example:

"elc_01kqzcjrpyf27tgekeyq3qzm7d"

​
site
object
required

A resolved resource reference as returned in responses.

​
period_start
string<date>
required

Start of the measurement period.

Example:

"2025-10-01T00:00:00.000Z"

​
period_end
string<date>
required

End of the measurement period.

Example:

"2025-10-31T00:00:00.000Z"

​
status
enum<string>
required

State of the background emission calculation.

  • calculating — calculation is in progress.
  • completed — calculation finished, emissions_in_kg_co2e is populated.
  • failed — calculation failed (contact support).
Available options:
calculating,
completed,
failed
Example:

"completed"

​
data_points
object[]
required

Resolved emission measurement data points.

​
file_ids
string[]
required

IDs of linked files.

Example:
[]
​
created_at
string<date-time>
required
read-only
Example:

"2026-05-06T19:34:00Z"

​
updated_at
string<date-time>
required
read-only
Example:

"2026-05-06T19:34:00Z"

​
external_id
string | null

Partner-assigned external identifier.

Example:

"GC-ELEC-2025-10"

​
display_key
string | null

Human-readable display identifier.

Example:

"GC-ELEC-2025-10"

​
emissions_in_kg_co2e
number | null
read-only

Total emissions for this period in kg CO2 equivalent. Null while status is calculating. Populated once calculation completes.

Example:

8942.37
