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. This is the stable identifier of the data point config, not the version 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 material sourcing step.

A material sourcing step execution as returned in responses.

​
id
string
required

Cula-assigned TypeID.

Example:

"stp_01kqzcjrpxf27tge33jwvjhkff"

​
config_id
string
required

Root step config ID.

Example:

"stc_01kqzcjrpyf27tgeeekpvvx0zt"

​
config_version_id
string
required
read-only

Resolved config version used at creation time.

Example:

"scv_01kqzcjrpyf27tgefhb58rc9d4"

​
site
object
required

A resolved resource reference as returned in responses.

​
executed_at
string<date-time>
required

When the step was executed. Stored and returned in UTC.

Example:

"2026-05-01T19:30:00Z"

​
data_points
object[]
required

Step-level resolved 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"

​
output
object[]
required

Output material containers with resolved data points and computed contents.

​
external_id
string | null

Partner-assigned external identifier.

Example:

"GC-HARVEST-2026-001"

​
display_key
string | null

Human-readable display identifier.

Example:

"GC-HARVEST-2026-001"

​
location
object

Override location. If the step was executed at a different physical location than the site, this field captures those coordinates. Cula attributes additional transport emissions for the distance between the site and this location.
