Common Guidelines for POST APIs

• idempotency_key
  • An idempotency_key can be used for the POST API (at headers).
    • If you want idempotence, add idempotency_key. (not required)
    • max_length = 300
  • The remaining APIs automatically guarantee idempotence.
  • reference

Confirm Payment

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

• request body

  {
      "amount":"1000",
      "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",
        "refund_receive_account": {   -> When a user pays with a virtual account, it is mandatory
            "account_number": "1234567",
            "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.
