Add a Payment Field

Add a Payment Field in the project editor.

Enter payment details

Enter the information required for the payment.

Variant key

A unique value that identifies a payment UI. You can find it in the Payment Field via Check Payment UI variant key.
Be careful to distinguish between live and test UIs — live UIs process real payments, while test UIs do not.
If you're just getting started, click the Add UI button to configure various payment UIs.
After clicking Add UI, select Domestic general payment.

Virtual accounts are not supported

Virtual accounts cannot be used. In the payment UI editor, go to [Features] → [Payment Method List] and make sure to uncheck virtual account. Walla records a payment as complete once a response is submitted after the payment request, but virtual accounts don't settle immediately — this can lead to responses marked as paid in the response sheet even though no deposit has actually been made.

Client key / secret key

You can find these under 'My Developer Info' in the Toss Payments Developer Center. Select your store on the left, then copy the client key and secret key for that store.

Order ID

A unique value used to identify each order payment, formatted as 'orderID_randomKey_time'. e.g., red bean bungeoppang → redbean, custard bungeoppang → chouxcream

Product name / price

Enter the name and price of the item the respondent will order.

Order form complete

You can now build your order form using the Payment Field.

Enter the variant key in the payment UI, and enter the client key and secret key in the payment widget.
Enter the order ID, product name, price, and other details, then save to finish.
Test UIs do not process real payments, so be careful to distinguish them from live UIs.
You can use logic to show different Payment Fields depending on the respondent's selections.
