didn't find the add card and save card ID flow
We would like to add Card from the mobile App (developed in Flutter) and save card ID in backend database, from backend we will charge customer from that saved card when needed, so how do we do that?
We have checked this already, checked almost whole document but didn't find the execat flow to add card and save card in backend.
We find remove card api, charge customer api, but didn't find the add card and save card ID flow.

Good afternoon @jason, thank you for reach us.
Which product are you trying to use? Is it paymentWidget? billing payment? brandpay?...
It's brand pay @Ayaan
Got it.
First, just for clarify, you cannot save the card number because of the Korean law.
Why do you want to save card information on your service?
Hi @Ayaan , We not want to save card info, we want to save card on payment gateway and want to save card ID on our server, so later on we can charge customer using that card id
Yes, Toss saves card data with CustomerKey that you sent on our SDK.
So you dont need to get any card information including card ID data, just simply save the customerKey and query to Toss API with the customerKey params.
Hi @Ayaan thanks, can you share document if it is avialble, I will check it and try
Only Korean version is available. But I hope you can use in-browser google translate feature in Chrome Browser.
If you are using Brandpay with PaymentWidget SDK which is newly deployed: https://docs.tosspayments.com/guides/payment-widget/integration-brandpay

Hi @Ayaan , Thanks, let me check it
Hi @Ayaan , I have checked it,
What I need is automatic payment using billing key.
I am not able to find How can I add card from Flutter App and get "authKey", can you please let me know this?
Or is there any other mode available where I can use Featue like "automatic payment using billing key"
authKey should be returned on your redirectUrl(if you are using webview to implement this) or return event(if you are using SDK directly).
@sunil008
I am not able to find it in SDK, can you share me the document url if possible? Also In webhook I am not able to find webhook for "Add Card" response
Which document did you found that information?

This is not brandpay, this is billing payment which is completely different product.
okay
Are you actually want to use BrandPay? I want to clarify this first.
Can you help me with the flow which one I should use?
I want automatic payment with Billing key
Automatic Payment?
Yes
Because I want to save card referenceId (BillingKey) to server and want to charge using that
Our automatic product is designed for case of regularly over a set period of time.
Do you think your business is suitable with this?
No, I want save customer card and I charge after the use of service
So you are going to use automatic payment without any scheduled, regularly payment right?
Yes, automatic payment without any scheduled
Alright. For this case, "BrandPay with BillingPayment" is more suitable I guess.
If you want, you can use normal billingpayment, but you will get very hard screening processes on this case.
There is a document (sadly only Korean supported, but as I mentioned you can use in-browser translation for this) that allows you to look at it.
Sorry, but can you please share link for "BrandPay with BillingPayment" ?
https://docs.tosspayments.com/reference/brandpay-sdk This JS SDK which you need to use on your client web/app.
https://docs.tosspayments.com/reference/brandpay-sdk#requestagreement%EC%95%BD%EA%B4%80-%ED%95%AD%EB%AA%A9 You'll need to call this function before user adds the card.
https://docs.tosspayments.com/reference/brandpay#%EC%9E%90%EB%8F%99%EA%B2%B0%EC%A0%9C-%EC%8B%A4%ED%96%89 This is API which you need to call from your server.

Please note, All Billing Payment products needs extra contract and needs the extra screening process to make contract.

Sorry it seems like Toss doesn't support flutter for brandpay yet.
I suggest you to develop your brandpay system with Web frameworks and use inappwebview to load this.
@sunil008
@Ayaan , instead of that can I use automatic payment?
So from mobile App I can call the API of Add card and send auth key to server. is this a good way instead of web view?
It may has a risk of skipping verification steps, which known as 3DS in overseas.
If you can't use webview and you should use API, yes you can, but it can be cause an issue on screening process by card companies in Korea.
More for this, I suggest you to message to Toss's contract team because I am not Toss Employee and I can't make you sure.
Hi @Ayaan Thank You for your support.
I will check the Flutter flow else will make the webview as you suggested.
혹시 한국어도 가능하신가요? @Ayaan
네 가능합니다. 한국어 영어 가능하고, 저는 베트남어로도 조금 소통할 수 있어 편하신 언어로 문의주시면 됩니다.
Yes, thank you for your understanding. Toss only supports official Flutter library just for normal transactions (not repeated), so please kindly understand that situation.
Please left your message here if you need any further help. I & Toss team will review and reply for you.
