@robintrson_14069 - Billing key Error NOT_SUPPORTED_METHOD
Original message by @Truong Thanh Son (#)
I am currently testing Toss Payment using the billing key add card method. After going through the steps of adding card information and the verification phone number, I encountered the following error: "인증만 지원하는 상점이 아닙니다." In the past, when testing, there was no step for verification via phone number, and I could add test card information normally. However, today I noticed that the interface has added a step requiring verification via OTP. Could you please support me with what I need to register next?

@Truong Thanh Son , You seems to trying the billing-key add card method.
However, the API key you used does not support billing-key payment.
Have you or your Korean colleague made the contract with us by any chance?
Or, what Client Key have you used?
I am using a test API key. The account has not registered for business verification.
My app is currently in development. About 1-2 weeks ago, the add card feature via billing method was working fine. Today, when the tester retested this part, they noticed changes in the interface (an added OTP verification step), and afterwards, this functionality can no longer be used.
Could you share the client key you used?
?
The key looks something like this
const clientKey = "test_ck_D5GePWvyJnrK0W0k6q8gLzN97Eoq";
YEP
Did you used same key that I sent you?
No, I am not using that key. I am using the key from my test account.
Due to the recent policy change
The key from your test account will not work for billing unless you contracted with us and associated with the business
Use this instead
const clientKey = "test_ck_D5GePWvyJnrK0W0k6q8gLzN97Eoq";
const secretKey = "test_sk_zXLkKEypNArWmo50nX3lmeaxYG5R";
Oh let's me try it, Thank you!
It seems that my API key has some limitations or something, after using your API key, everything returned to normal.
I guess I need to remind my boss to register the business with Toss 😄
It’s great to hear the issue was solved.
After contract with us, you will get the key with no limitations.
Just keep in mind that, the key I have shared can only be used for developing and cannot be used when you contract
I get it, Thank you
