How to test Toss Payment Widget in test environment without a real bank account?
Hello Toss team,
I'm currently integrating Toss Pay using your payment widget and would like to test the payment flow in the test environment. However, it seems like I’m being asked to enter a real domestic bank account even in test mode (as shown in the screenshot attached).
I have reviewed your documentation, but couldn't find any information about test accounts or sandbox data for simulating the payment process using Toss Pay (especially for methods like quick transfer, credit card, etc.)....

How can I check "client key" and "secret key" for my other MID?
Hello, I have 2 MID, one for Korean cards and other one for overseas credit card.
For payment widget, I can check "client key" and "secret key" for "yamallevwi" but not for MID "yanolj5c95".
I can only check for the API, not PAYMENT WIDGET. Could you help me to find "client key" and "secret key" for Payment widget MID yanolj5c95 In addition, is the error shown in the image supposed to be shown so it doesn't charge you....

want to confirm about lastTransactionKey in payment object
If I send two cancel requests in a short time, say that Toss receive both requests before I get any response, will the lastTransactionKey correctly refer to the exact cancel from the request I sent. Or it is not guaranteed?

Where is this error coming from?
Some credit selection is throwing this error. This happened when I selected VISA from this link. https://developers.tosspayments.com/sandbox/fail?code=COMMON_ERROR&message=%EC%B2%98%EB%A6%AC%20%EC%A4%91%20%EC%98%A4%EB%A5%98%EA%B0%80%20%EB%B0%9C%EC%83%9D%ED%96%88%EC%8A%B5%EB%8B%88%EB%8B%A4&orderId=MC43ODA5MjgwNDE4NzM5
Can I test with virtual credit card? Thanks....

question about transactionKey format in cancel
I need to find a way to separate between 「transactionKey of a cancel record」 and 「the order id from my side」.
Example id from my side: ARYAeLMaTLw1wUzlhrxsUjlhq1k7

want to confirm cancel status categories
I serached in the api docs and found that for a single cancel, "DONE" means the cancel is successful(pic1). What are the status for failure, or processing, and any other status?
I've also found some status flow chart from webhook page (pic2), so just want to confirm is this the same for api response?...

SDK payment window test environment: cannot get success url after execution
Our codebase use api v1, and the code snippet is in pic 1, so after loading the snippet in browser, the window is automatically redirected to google.com.
It's different result from the api docs:
"If the method execution is successful, the selected card company or simple payment company's own window will open as shown above. To complete the payment,Request payment authorization.
If the method execution fails, the rejected error can be handled in the catch block of the Promise.Error CodeTake a look at ."

PayPal Integration - refusing money
We have integrated PayPal into our webshop and are already using the live key. When customers pay for a product, the order is marked as paid in the webshop, and the money is deducted from the customer. However, 15 minutes later, the amount is refunded with the reason "Denied." On the Toss Dashboard, there are no transactions visible at all.
Payco integration questions
1. Does PAYCO support refunds?
- if yes, is there a time limit (e.g. 1 year?)
- if yes, is there a max/min amount for refund?
2. Does PAYCO support cancel?...
