Since M8465 r204, it is possible to add your configured data definition as an additional return parameter for a REST Process.

By default, REST Processes return the return values from the Architect Process.

Additionally, you can add two types of manual return parameters.

1. Single expressions / values (e.g. string, int)
2. A (filtered) data definition, like with GET Rest Data Definition End points

## Adding single values to return values

Go to REST Process return values. Here, you can add a parameter to give a result:

This adds, next to the already-available return parameters, my custom value:

```auto
{
    "success": true,
    "error": null,
    "response": {
        "user": 9,
        "given_username": "my_username@novulo.com"
    },
    "httpcode": 200
}

```

## Adding Data definitions to REST Processes

To add data definitions, go to more \> POST process return values. (They also work with PUT, PATCH, DELETE).

This gives you these two additional grids:

Here, for the Data defintion return values, you can add a Data definition. In this example, the data definition represents the just-added CMS user:

With the result being the part in `dd_user`.

```auto
{
    "success": true,
    "error": null,
    "response": {
        "user": 11,
        "dd_user": [
            {
                "id": 11,
                "username": "my_username3@novulo.com"
            }
        ],
        "given_username": "my_username3@novulo.com"
    },
    "httpcode": 200
}

```
