Payment

• Reserve a payment

# Proceed sales with capture
params = %{
  amount: 1000,
  confirmUrl: "myapp://line_pay",
  currency: "JPY",
  orderId: "#1",
  productName: "foobar"
}

{:ok, payment} = LinePay.Payments.reserve(params)

# If you want to separate the authorization process, specify `capture` to `false`.
params = %{
  amount: 1000,
  confirmUrl: "myapp://line_pay",
  currency: "JPY",
  orderId: "#1",
  productName: "foobar",
  capture: false
}

{:ok, payment} = LinePay.Payments.reserve(params)

• Confirm a payment

params = %{amount: 1000, currency: "JPY"}

{:ok, payment} = LinePay.Payments.confirm("transaction_id", params)

• Capture a payment

params = %{amount: 1000, currency: "JPY"}

{:ok, payment} = LinePay.Payments.capture("transaction_id", params)

• Refund a payment

{:ok, payment} = LinePay.Payments.refund("transaction_id")

• Partially refund a payment

{:ok, payment} = LinePay.Payments.refund("transaction_id", %{refundAmount: 500})

• Invalidate the authorized payment

{:ok, payment} = LinePay.Payments.void("transaction_id")

• Get payments detail.

# Get payments by transaction id
{:ok, payment} = LinePay.Payments.get(transactionId: 2017101800001000)

# Get payments by order id
{:ok, payment} = LinePay.Payments.get(orderId: "#5")

# You can specify both transaction id and order id
