class Invoice(Resource):
    """# Invoice object
    When you initialize an Invoice, the entity will not be automatically
    sent to the Stark Bank API. The 'create' function sends the objects
    to the Stark Bank API and returns the list of created objects.
    To create scheduled Invoices, which will display the discount, interest, etc. on the final users banking interface,
    use dates instead of datetimes on the "due" and "discounts" fields.
    ## Parameters (required):
    - amount [integer]: Invoice value in cents. Minimum = 0 (any value will be accepted). ex: 1234 (= R$ 12.34)

    - discounts [list of dictionaries, default []]: list of dictionaries with "percentage":float and "due":datetime.datetime or string pairs
    - rules [list of Invoice.Rules, default []]: list of Invoice.Rule objects for modifying invoice behavior. ex: [Invoice.Rule(key="allowedTaxIds", value=[ "012.345.678-90", "45.059.493/0001-73" ])]
    - tags [list of strings, default []]: list of strings for tagging
    - descriptions [list of dictionaries, default []]: list of dictionaries with "key":string and (optional) "value":string pairs
