# `prefect.server.api.task_runs`



Routes for interacting with task run objects.


## Functions

### `create_task_run` <sup><a href="https://github.com/PrefectHQ/prefect/blob/main/src/prefect/server/api/task_runs.py#L52" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

```python
create_task_run(task_run: schemas.actions.TaskRunCreate, response: Response, db: PrefectDBInterface = Depends(provide_database_interface), orchestration_parameters: Dict[str, Any] = Depends(orchestration_dependencies.provide_task_orchestration_parameters)) -> schemas.core.TaskRun
```


Create a task run. If a task run with the same flow_run_id,
task_key, and dynamic_key already exists, the existing task
run will be returned.

If no state is provided, the task run will be created in a PENDING state.

For more information, see https://docs.prefect.io/v3/concepts/tasks.
