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
}
}
