# Duplicate form data API
## Availability
Since Orbeon Forms 4.7.
## Internal uses
The API is also used internally by the Summary page via the Duplicate button.
## Purpose
The purpose of the `duplicate` API is to duplicate form data, including form data attachments. This API cannot be used to duplicate [autosaved data](https://doc.orbeon.com/form-runner/persistence/autosave), as it doesn't provide a way for the caller to specify whether the data to duplicate was autosaved or not.
## Interface
* URL: `/fr/service/$app/$form/duplicate`
* Method: `POST`
Where:
* `$app` is the form definition's application name
* `$form` is the form definition's form name
Request body:
* `Content-Type: application/xml`
* the element contains the document id to duplicate
Example request body:
```xml
51dfcf49bb4b7f994906a26911003e4a999f1e39
```
Response body:
* `Content-Type: application/xml`
* the element contains the newly created document id
Example response body:
```xml
c0f6dd2e75e94f60b9493768843e3fdef2af6bc0
```
## Permissions
The caller must either call the service internally or have proper credentials to access the data (username, group, roles).
