Retrieve a process impact

Fetch a single impact row on a process. Useful when you only care about one (method, indicator) pair and don't want to download the full process payload.

GET/public/processes/:id/impacts/:impactId

Companion to GET /public/processes/:id — same masking, but returns only the named impact row. If the impact doesn't belong to the given process, you get a clean 404Not Found instead of silently returning an impact from a different process.

Path parameters

Parameter	Type	Description
idrequired	string (uuid)	The process id.
impactIdrequired	string (uuid)	The id of the impact row to retrieve.

Response

200OK

If revealed is false, every sensitive numeric field (value, mean, standardDeviation, …) is masked to null. Purchase access via POST /processes/:id/impacts/pull.

Errors

404Not Foundwhen the process doesn't exist, the impact doesn't exist on this process, or either record is soft-deleted.
