# Rollback Content Type Version

> Rollback to a previous version of a content type

Restores a content type to a previous version's configuration. This creates a new version with the historical configuration, rather than overwriting history.

## Path Parameters

<ParamField path="organizationId" type="string" required>
  Organization ID
</ParamField>

<ParamField path="projectId" type="string" required>
  Project ID
</ParamField>

<ParamField path="id" type="string" required>
  Content Type ID
</ParamField>

<ParamField path="version" type="number" required>
  The version number to rollback to
</ParamField>

## Response

Returns the updated ContentType object with a new version number containing the rolled-back configuration.

```json theme={null}
{
  "id": "ct123",
  "name": "Article",
  "status": "published",
  "version": 4,
  "lastPublishedVersion": 4,
  "rootComponentId": "c123",
  "config": {
    "allowedComponents": ["c124", "c125", "c126"]
  },
  "packageVersion": "1.0.0",
  "schema": { ... },
  "templateContentIds": ["cont123"],
  "permissions": { ... },
  "metadata": {
    "author": "admin@metabind.ai",
    "tags": ["article"],
    "publishedAt": "2024-03-23T10:00:00Z",
    "publishedBy": "user123"
  },
  "createdAt": "2024-03-20T10:00:00Z",
  "updatedAt": "2024-03-23T10:00:00Z"
}
```

<Note>
  Rollback creates a new version (e.g., rolling back from v3 to v2 creates v4 with v2's configuration). This preserves the complete version history.
</Note>
