Confirm Payment

toss_client.confirm(payment_key: str, toss_order_id: str, amount: int, idempotency_key: str = None)

• request body

      "orderId":"ORDER_ID_THAT_YOU_CREATE",  -> need to create when creating your payment data
      "paymentKey":"PAYMENT_KEY_FROM_FRONT_END",  -> We receive it from the front-end.
  }
  

Cancel Payment

toss_client.cancel(payment_key: str, cancel_data: dict, idempotency_key: str = None)

• request body

    cancel_data = {
        "cancel_reason": "단순변심",  -> required
        "cancel_amount": 1000,
        "curreny": "KRW",
        "divided_payment": "True",

            "bank": "13",
            "holder_name": "test" 
        },
        "tax_amount": 100,
        "tax_exemption_amount": 0,
        "tax_free_amount": 0,
    }
  

  • Because we send our payment_key in the headers, we can simply add the required data when posting to the cancel API.
    • cancel_reason, refund_receive_account (case of virtual_account)
    • If you want to include the remaining data, you are allowed to do so.
