# Set a per-job task YAML override

> Source: https://docs.clonepartner.com/api-reference/jobs/set-job-task-override/

`PUT /api/jobs/{id}/tasks/{taskKey}/override`

Stores a YAML override for the given DAG node key. The override wins over
the pinned task version at run time for this job only. Validated with the
same task parser/validator as the task library, plus bidirectional connector
slot checks: every slot in the DAG node's connector_mapping must be declared
in the override's `connectors` section, and the override may not introduce
slots that the job has no mapping for. Admin only.

**Operation ID:** `setJobTaskOverride`
