# Update Trigger

`PATCH /api/v1/triggers/{trigger_id}`

## Request

- The document declares no server URL.
- Auth: one of:
  - OAuth 2
    - Password
    - Token URL: `api/v1/login`
  - API key in query parameter `x-api-key`
  - API key in header `x-api-key`

## Path parameters

- `trigger_id` string, uuid, required

## Request body

- TriggerUpdate: Partial update. Every field is optional; unset fields are left alone.
  - `binding_target` 'flow' | 'deployment': What a fired event runs. ``flow`` runs the saved flow (or the pinned ``flow_version`` when set) through the background execution service. ``deployment`` is stored but not dispatched in 1.13 — see :class:`BindingUnsupportedError`.
  - `concurrency_limit` integer, nullable
  - `config` object, nullable
  - `connection_id` string, uuid, nullable
  - `deployment_id` string, uuid, nullable
  - `flow_version_id` string, uuid, nullable
  - `max_attempts` integer, nullable
  - `name` string, nullable
  - `session_policy` 'per_event' | 'shared': How a dispatched run derives its session id when the payload has no conversation.
