# Rename a project

> PATCH /v1/projects/:id — rename a project owned by your account.

<Info>**PATCH** `https://api.craftkit.dev/v1/projects/{id}`</Info>

Rename a project. The slug is not recomputed — renaming never changes `slug` or breaks existing
project-key integrations.

## Authorization

<ParamField header="Authorization" type="string" required>
  `Bearer ck_acct_…` — must own the project.
</ParamField>

## Path

<ParamField path="id" type="string" required>The project id (UUID).</ParamField>

## Body

<ParamField body="name" type="string" required>New display name (1–200 chars).</ParamField>

## Response

`200` — the full project, `slug` unchanged:

<ResponseField name="id" type="string" />

<ResponseField name="slug" type="string">Unchanged — renaming never recomputes the slug.</ResponseField>
<ResponseField name="name" type="string">The new name.</ResponseField>

<ResponseField name="createdAt" type="string" />

<ResponseField name="updatedAt" type="string" />

## Errors

Ownership is resolved **before** the body is read, so an id you don't own returns `404` even if the
body is also invalid.
