# Trigger Run

`POST /api/v1/steps/project/{project_id}/run`

Trigger a new run for a project.

- root_step_id=None → run all active steps (Run All).
- root_step_id=<id> → refresh that output: runs its ancestor closure back to roots.
  The target must be a ``database`` step.

## Path parameters

- `project_id` string, uuid, required

## Request body

- RunCreate — Trigger a new run. ``root_step_id`` is the target output (a database step). Null ``root_step_id`` means Run All — run every active step in the project. Project runs intentionally expose execution controls only. Runtime parameters belong to an App-invoked Automation; rejecting unknown fields prevents obsolete clients from silently submitting ignored ``input_data``. ``force_full`` bypasses the AI Lambda's content-addressed cache / the custom Lambda's api_action ledger for this run only — used for manual replays after schema changes or bug fixes. Cascade-created runs leave this False (see spec §7d — force_full does not propagate through cascade).
  - `root_step_id` string, uuid, nullable
  - `force_full` boolean
