## Send NULL values to a Dataset

Lots of our customers use the Datasets API to pull data into Geckoboard from their own database, so I'm pleased to say we now support sending NULL values to a Dataset.

Any of the numeric field types (number, percentage, or money) can accept NULL values. You'll need to specify in your schema that you want a field to accept NULL values by setting the _optional_ parameter:

```
"fields":{
  "customers":{
    "type": "number",
    "name": "Customers",
    "optional": true
  }
}
```
