Hi,

I’m trying to update the records in a data group via the REST API, but when I use the following BODY in the PUT

```tcl
{
    "records": [
        {
            "name": "test",
            "data": "data"
        }
    ]
}

```

I get the following error

```tcl
{
    "code": 400,
    "message": "0107074b:3: Unable to change data group (/Common/testdg) type.  Must remove existing entries first.",
    "errorStack": [],
    "apiError": 3
}

```

Any thoughts appreciated.

Cheers,

Simon

I would try this

Thanks, Dario

That was very useful

I managed to get the records to add using the PATCH method described in the article

To add a string record I had to use the following querystring, where test is the name of the record and stuff being the value

```tcl
/mgmt/tm/ltm/data-group/internal/~Common~testdg?options=records add { test { data stuff } }

```

That returned the expected result

```tcl
{
    "kind": "tm:ltm:data-group:internal:internalstate",
    "name": "testdg",
    "partition": "Common",
    "fullPath": "/Common/testdg",
    "generation": 184,
    "selfLink": "https://localhost/mgmt/tm/ltm/data-group/internal/~Common~testdg?options=records+add+%7B+test+%7B+data+stuff+%7D+%7D&ver=14.1.0.3",
    "type": "string",
    "records": [
        {
            "name": "test",
            "data": "stuff"
        }
    ]
}

```

Would still be interested to hear if using the PUT method is a known issue??

Cheers,

Simon

Looks like I should have paid more attention to the error.

I noticed it was complaining about trying to change the type, so adding the type:string to the JSON body resolved my issue.

```tcl
{
    "type":"string",
    "records": [
        {
            "name": "test",
            "data": "stuff"
        },
        {
            "name": "testing",
            "data": "more stuff"
        }
    ]
}

```

The behavior of PUT/PATCH was changed lastly (new releases).

The relation between tmsh and icontrol is similar to this:

GET - list/show

POST - create

PUT - update

PATCH - modify

DELETE - delete
