# Trigger a line run

POST https://api.islo.dev/factory/lines/{name}/runs
Content-Type: application/json

Reference: https://docs.islo.dev/api-reference/factory/trigger-factory-line-run

## Authentication

- `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer <token>`, where token is your auth token.

## Request

### Path parameters

- `name` (string, required)

### Body (application/json)

This endpoint expects a LineRunCreate.

- `version_id` (string, optional, nullable) — Deployed line version to run; defaults to latest
- `region` (string, optional, nullable) — Compute region override
- `params` (map from string to any, optional)
- `trigger_payload` (map from string to any, optional)

## Response

### 202

Successful Response

- `id` (string, required)
- `line_name` (string, required)
- `line_version_id` (string, required)
- `workflow_run_id` (string, required)
- `status` (string, required)
- `trigger` (TriggerSummary, required) — What set a run off. `provider`, `event_name`, and `delivery_id` are lifted out of the nested `payload.trigger` object so a list row is readable without walking the envelope. The extracted trigger values are not repeated here; they land in the run's `run_params`. `payload` still carries the whole envelope, minus the raw webhook body on list responses.
- `created_at` (datetime, required)
- `region` (string, optional, nullable)
- `run_params` (map from string to any, optional)
- `result_payload` (map from string to any, optional, nullable)
- `error_message` (string, optional, nullable)
- `iteration_count` (integer, optional, default: 0)
- `budget_used_usd` (string, optional, nullable)
- `compute_cost_cents` (integer, optional, default: 0)
- `inference_cost_cents` (integer, optional, default: 0)
- `total_cost_cents` (integer, optional, default: 0)
- `cost_rated_at` (datetime, optional, nullable)
- `retry` (LineRunRetryAction, optional, nullable)
- `stages` (list of LineRunStageDetail, optional)
- `failure` (LineRunFailure, optional, nullable) — Why a line run ended, and which step surfaced it. Orchestrator classification (``code``, ``domain``) is written into ``result_payload`` on terminal paths. Step diagnostics are enriched in by the API without replacing those fields. Read out of ``result_payload`` rather than carried as its own request field. ``api`` and ``workflow-handlers`` are separate Deployments with no rollout ordering, so a new key on a request body is rejected by whichever old pods are still serving — and on ``LineControlWaitRequest``, which forbids extras, that rejection would finalize a succeeded run as failed. Unknown keys are tolerated for the same reason, in the other direction: a later orchestrator that adds a field here must not make every failure read as unclassified while the rollout is in flight.
- `triggered_by_actor` (map from string to any, optional, nullable)
- `started_at` (datetime, optional, nullable)
- `completed_at` (datetime, optional, nullable)

### LineRunFailure

Why a line run ended, and which step surfaced it. Orchestrator classification (``code``, ``domain``) is written into ``result_payload`` on terminal paths. Step diagnostics are enriched in by the API without replacing those fields. Read out of ``result_payload`` rather than carried as its own request field. ``api`` and ``workflow-handlers`` are separate Deployments with no rollout ordering, so a new key on a request body is rejected by whichever old pods are still serving — and on ``LineControlWaitRequest``, which forbids extras, that rejection would finalize a succeeded run as failed. Unknown keys are tolerated for the same reason, in the other direction: a later orchestrator that adds a field here must not make every failure read as unclassified while the rollout is in flight.
