title: Update Project info
description: Update General Translation Project-level settings from automation. API reference for updating Project information.

method: POST
---

Updates Project-level settings such as the default locale. The Project ID in the path must match the authenticated Project.

## Overview [#overview]

```http
POST https://api2.gtx.dev/v2/project/info/:projectId
```

**Permission** `project:write` · **Rate limit** Default (200/min)

Change a Project's settings using your own automation. To read the current settings, use [Get Project information](/docs/platform/openapi/reference/project/project-info).

## How it works [#how-it-works]

* The `projectId` in the path must match the Project the API key is authenticated for. A missing or mismatched ID returns `400`.
* When `defaultLocale` is provided, it is validated and set as the Project's default locale. Omitting it leaves the default locale unchanged.
* The response confirms success.
