PUT /api/v11/workflows/{id}

### Description

Update a workflow. All values should be provided in the request. If not provided any missing values are reverted to default.

### Parameters

Parameter | Description | Type | Parameter Type | Required
--- | --- | --- | --- | ---
id | The id of the workflow being updated | integer | path | Yes
name | The workflow name. Will be compared against other workflows and rejected if not unique | string | body | Yes
owners | A list owners for the workflow. Can be users or group names (prefixed with swarm-group-). Users and group names must exist or the workflow will be rejected | array (of strings) | body | Yes
description | Description for the new workflow | string | body | Yes
shared | Whether this workflow is shared for other users that do not own it. Defaults to not shared | boolean | body | Yes
mode | Workflow rules: Each workflow rule must have a mode parameter. The only valid value for mode is inherit. Global workflow rules only: default applies the workflow rule setting to projects and project branches that don't have an associated workflow. If a project or project branch has an associated Swarm workflow, the global rule is ignored. policy applies a minimum workflow rule setting to all projects and project branches. If a project or project branch has an associated workflow, the global rule is merged with the workflow rule and the most restrictive setting is used. Displayed as Enforce on in the P4 Code Review UI, see Global workflow. | string | body | Yes
on_submit | Data for rules when changes are submitted. Valid values for with_review are no_checking, approved, strict. Valid values for without_review are no_checking, auto_create, reject | array | body | Yes
end_rules | Data for rules when changes are submitted. Valid values are no_checking, no_revision. | array | body | Yes
auto_approve | Data for rules when changes are submitted. Valid values are votes, never. | array | body | Yes
counted_votes | Data for rules when counting votes up. Valid values are anyone, members. | array | body | Yes
tests | A list of test ids for the workflow. Each test id has an event that determines when the test is run and a blocks value that determines whether a test failure blocks review approval. Valid values for event are onUpdate, onSubmit. Valid values for blocks are nothing and approved. | array | body | No
