How to receive the Webhook call for toss in local environment?
I am working on an implementation for Toss Payment SDK. I have implemented the order placement, confirm API and cancel API call. Also, I have configured the Webhook and pointing to my local environment for development & debugging. I am not receiving any webhook calls to my local environment.
Would you be able to assist me on this?

Are you working for Korean company? Did you have our developer center account which connected to your company information?
Yes.
What is your merchantId? If you dont' know what is merchantId plz share your url after you login to your developer center
The Webhooks working fine now, the issue was authentication.
Thanks for sharing. We're glad the problem has been resolved.
I have one more doubt, I am executing cancel API call for one of the order. However, I am getting below error. Could you please confirm why it is happening? I have given proper accountNumber for that order.
Response:
{
"code": "INVALID_REFUND_ACCOUNT_NUMBER",
"message": "ìž˜ëª»ëœ í™˜ë¶ˆ 계좌번호입니다."
}
Request:
{"cancelReason":"Customer wants refund","cancelAmount":"390000","refundReceiveAccount":{"bank":"31","accountNumber":"X600802567548","holderName":"Pankaj"},"taxFreeAmount":0,"currency":"KRW","refundableAmount":"390000","paymentKey":"tmcmk202409031930224rlW8”}
@pankaj.mahapatra@gspann.com First of all,
Please make sure your server uses UTF-8, not ANSI or EUC-KR; your response was:
As you can see the code is INVALID REFUND ACCOUNT NUMBER.
It is sent when accountNumber field on request is malformed.
Why do you send the account number starts with "X"? It should be numbers.
Hi @Ayaan - I am using UTF-8 only and my account number is starts with X because when we place the order and execure Confirm API I get below response for that Order. And for the same order only I am using the account number to refund, please find the below response for the same -

@pankaj.mahapatra@gspann.com You should get accountNumber from your customer.
"X600802567548" is the account number that needs to be transfered(paid) from customer.
On cancel API, Toss needs to transfer back to customer, and refundReceiveAccount is used for this.
Customer means here 'Merchant' or 'End User'?
In the above Confirm API response, how do I get to know the Customer Account number in order to initiate Cancel API?
Ok, let me explain to you step-by-step.
First, the store receives payment from the customer (end user).
When calling the Confirm API, an accountNumber is received. ("X600802567548")
The payment is completed when the customer deposits the money with this account number, "X600802567548".
When canceling/refunding, the exact opposite happens.
When calling the Cancel API, the customer(end user)'s accountNumber is sent to the refundAccountNumber.
You can request this separately from the customer, or if you use a payment widget, you can create a UI that receives the input when the payment is first received.
After the cancellation is completed, the money is deposited to the refundAccountNumber entered by Toss Payments, and the refund is completed.
At this point, you can see why you received that error.
You need to pass the customer's account number to receive the refund, but you are sending the account number of the merchant where the customer should pay(which is accountNumber transmitted on confirm API, "X600802567548"), so that is why you received that error.
@pankaj.mahapatra@gspann.com
We are in Development phase of Confirm and Cancel API. So, in test environment, can we use any random account number in order to successfully refund?
Also, I have one more doubt, you mentioned, The payment is completed when the customer deposits the money with this account number, "X600802567548".
So, once customer deposit the amount, how Toss will get to know and complete the payment? Is it through Webhook the integrated platform will get to know that payment is completed successfully and we can now proceed to export the order.
@Ayaan - Yes, we do have a Korean employee. However, I was wondering why do we need original account number for testing the refund flow on Test Environment. We have not release the feature yet. So, there should be some dummy account number where we can generate refund for testing as we are in Implemetation & testing phase.
@pankaj.mahapatra@gspann.com Can you provide random number on refundReceiveAccount.accountNumber?
I checked that any dummy accountNumber that fits on Korean bank account numbering rule can be used for test env.
@Ayaan - I just tried with below random 11 digit Account number but getting same error -
Request:
{
"cancelReason": "Customer wants refund",
"cancelAmount": "930000",
"refundReceiveAccount": {
"bank": "45",
"accountNumber": "98765432101",
"holderName": "Pankaj"
},
"taxFreeAmount": 0,
"currency": "KRW",
"refundableAmount": "930000",
"paymentKey": "tmcmk202409032033069Wbd7"
}
Are you still getting INVALID_REFUND_ACCOUNTNUMBER?
Are you using the secret key that starts with test(gsk|sk) right?
Yes, we are getting same error. Yes, secret key starts with "testgsk"
I am not quirte sure why it doesn't work. If so, we need to forward to Toss Team as it still doesn't work.
I tried with below and it worked.
Bank code 31
1600802567580
@pankaj.mahapatra@gspann.com Is that number is real number? or random generated number?
Random
I have one more question, if we cancel from the toss console manually when payment is waiting for Deposit then we don't need to execute Cancel API right. FYR, PFA.
Yes. You don't need to call API if it is canceled manually.
FYI, if you call API when it is waiting for deposit, it invalidates the virtual account number.
In this case, you don't need to send refundAccountNumber as it's not paid.
Thanks for all the information, I have one last question, for payments like Easy payment or Card payment the payment capture will be upfront right. It won't need all these procedure like Virtual Account for Bank Transfer.
I don't understand your question.
Payment capture is automatic for most of merchants
I meant to say, for Card Payment and Easy Payments when we initiate Confirm API, we don't see "Deposit Processing" options.
Yes, deposit process/waiting for deposit is only for virtual accounts
@pankaj.mahapatra@gspann.com
@Ayaan - Could you let me know for a Bank Transfer payment how many days the order will be in "Waiting for deposit" until end user deposit the amount in Bank? When it will be expired and auto cancel by Toss?
@pankaj.mahapatra@gspann.com Default is 7 days from the time that you requested confirm API.
However, you can adjest it if you needed. Maximum is 30 days.
@Ayaan - Could you point me to the document please? Also, after 7 days, for the expired order, toss will automatically cancel the transaction and make a Webhook call right.
yes. it changes to "EXPIRED" status.
It will be PAYMENT_STATUS_CHANGED webhook issued.
@pankaj.mahapatra@gspann.com Are you using payment widget?
yes
@Ayaan - Could you point me to the document please where it is mentioned for Default is 7 days and how to change it to Maximum 30 days?
if so, the due date of deposit is managed by on Admin Backoffice in Toss website, so there's no documentation.
This is what is going to be look like on Backoffice page.
https://consumer.tosspayments.com/ex/payment-widget?device=mobile&preference=function&menu=method-settings
word-by-word translation:
"가상계좌 입금기한" -> "Deposit due-date"
"7일" -> 7 days
"0시간" -> 0 hours
"0분" -> 0 minutes
"최대 30일까지 설정할 수 있어요." -> "You can set this option to maximum 30 days."
Thank you for the information.

Hi @Ayaan - When do we get the below payment status "interruption" for Web-hooks and how to reproduce it?
Hmm, Can you screenshot without translating please? I am not quite sure about the error message you got.
Thank you for confirm it.
I think, I should pass this issue to Toss team to check the log. As it's friday night in Korea, response might be delayed until Monday.
@Ayaan - One last question, we are trying to partially cancel one order which is placed with two qty same item. Order placed with "NAVERPAY" . Below is the request and response for the same -
Request:
{
"cancelReason": "Customer wants refund",
"cancelAmount": "374000.00",
"taxFreeAmount": 0,
"currency": "KRW",
"paymentKey": "tmcmk20240927210734DWkU8"
}
Response:
{
"code": "NOT_CANCELABLE_PAYMENT",
"message": "This is a non-cancelable payment."
}
Can't we partially cancelled 1 qty for an order of same item?
@pankaj.mahapatra@gspann.com - Please make sure that Korea doesn't supports float amount to pay/cancel. Only integer is supported
Change "374000.00" (float-typed string) to 374000 (integer) and try again.
If integer is also doesn't work, please give us the orderId, then Toss Team will check the log and assist you, as well as Interrupted payment that you shared before.
Below is the request and response for the interuppted status.
Request:
{
"paymentKey": "tmcmk20240927150837JtNc6",
"orderId": "F48823437",
"amount": 964000
}
Response:
{
"code": "FAILED_INTERNAL_SYSTEM_PROCESSING",
"message": "Internal system processing operation has failed. Please try again in a few minutes."
}
Thanks, well-noted.
Just for confirm,
tmcmk20240927210734DWkU8 is for NOT_CANCELABLE_PAYMENT error,
and tmcmk20240927150837JtNc6 or F48823437 is for FAILED_INTERNAL_SYSTEM_PROCESSING error and interruppted status in webhook, right?
@pankaj.mahapatra@gspann.comYes, that is correct.
Hi @Ayaan - I am seeing the payment status is not getting updated in toss when we initiate the cancel request even though we are getting the proper response from service.
Request:
{
"cancelReason": "Customer wants refund",
"cancelAmount": "1150000",
"refundReceiveAccount": {
"bank": "31",
"accountNumber": "1600802567580",
"holderName": "Test"
},
"taxFreeAmount": 0,
"currency": "KRW",
"paymentKey": "tmcmk2024093017543818Vd9"
}
It was working till yesterday.
Hi @pankaj.mahapatra@gspann.com - I sincerely apologies for the inconvenience.
However, your error needs to be investigated by the Toss team using the appropriate logs saved by Toss, so please give us some time to investigate.
cc @이실장 Please check the logs and f/u to them 😄
Oh just for you know @pankaj.mahapatra@gspann.com - tomorrow is public holiday in Korea. Investigation might be delayed due to this.
ok
How to forward to @이실장 ?
He will check this thread when he available
ok
@Ayaan - Please let me know ASAP if you find the root cause. Also, do you think it could be a glitch because we have configured 3 different instances Web-hooks:
Test payment history is a feature provided for development convenience. Therefore, some errors may occur. Please focus on checking the status retrieved from the API.
I don't think it is caused by multiple webhooks, as Toss sends SAME RESPONSE for all webhooks
