Tax , Promocodes and extraData

Tax

The first is a tax field which is optional and can be used to add a fixed amount of tax.
If your site has already calculated the tax for an order, this field can be used. The tax field will accept a float value representing the tax amount.

Set the tax field with the following format

JSON

"tax" : {
    "amount" : 10.00,
    "rate" : 0.1,
    "shipping_inclusive" : true
}

Variable	Type	Description	Default Value
amount	Decimal	Tax Amount	0.00
rate (Optional)	Decimal	Tax rate in decimal. 10% is 0.1	0.00
shipping_inclusive	Boolean	if set to true shipping is also counted as tax	FALSE

Another important field in the order is the extraData field which is used to store any additional information about the order.
Since it is a required field, if you have no extra data that needs to be added to the order you can simply store your website URL within the field.
