# update\_feature

Update a feature's Gherkin and/or rename it. Both body fields are optional — send what you want to change.

{% hint style="warning" %}
Rejected with `409 conflict` while the feature is `generating`. Updating the Gherkin does **not** regenerate tests — follow up with [`generate_feature`](/testvibe-api/api-reference/generation/generate_feature.md).
{% endhint %}

## Request

PATCH /api/v1/ops/projects/{project}/features/{feature}
```

| `feature` | path | string | yes      | Feature id or name.      |
