# Delete a Determining Attribute

You can delete determining attributes one at a time using this method. The call is defined as ‘DELETE’ instead of ‘POST’ or ‘PATCH’.

The determining attribute ID shown above is for the ‘data\_block\_based’ seen below.

Prior to deletion, you can see the determining attribute in TDO.

The body of the message is the same as for ‘get details’ API’s.

```
{
    "context": {
        "user": "mbj_test",
        "password": "xxxx",
        "project": {
            "name": "imp_payments_demo",
            "version": "1.0"
        }
    }
}
```

When run, the message only shows the successful completion of the call.

Checking the determining attributes list in TDO, this attribute is no longer present.

Remember, only users with administrative credentials can delete objects in TDO.
