  When you initialize a BoletoPayment, the entity will not be automatically
  created in the Stark Bank API. The 'create' function sends the structs
  to the Stark Bank API and returns the list of created structs.

  ## Parameters (conditionally required):
    - `:line` [string, default nil]: Number sequence that describes the payment. Either 'line' or 'bar_code' parameters are required. If both are sent, they must match. ex: "34191.09008 63571.277308 71444.640008 5 81960000000062"
    - `:bar_code` [string, default nil]: Bar code number that describes the payment. Either 'line' or 'barCode' parameters are required. If both are sent, they must match. ex: "34195819600000000621090063571277307144464000"

  ## Parameters (required):
    - `:tax_id` [string]: receiver tax ID (CPF or CNPJ) with or without formatting. ex: "01234567890" or "20.018.183/0001-80"
    - `:description` [string]: Text to be displayed in your statement (min. 10 characters). ex: "payment ABC"

  ## Parameters (optional):
    - `:scheduled` [Date or string, default today]: payment scheduled date. ex: ~D[2020-03-25]
    - `:tags` [list of strings]: list of strings for tagging

  ## Attributes (return-only):
    - `:id` [string, default nil]: unique id returned when payment is created. ex: "5656565656565656"
    - `:status` [string, default nil]: current payment status. ex: "success" or "failed"
    - `:amount` [int, default nil]: amount automatically calculated from line or bar_code. ex: 23456 (= R$ 234.56)
    - `:fee` [integer, default nil]: fee charged when a boleto payment is created. ex: 200 (= R$ 2.00)
    - `:created` [DateTime, default nil]: creation datetime for the payment. ex: ~U[2020-03-26 19:32:35.418698Z]
