Test data

Everything here works in the Kustom playground environment only, and none of it moves money. Use it to complete checkouts end to end while you build. Don’t test with real customer data — these addresses and payment details exist so you never have to.

Sample customer data

Use the row for the market you’re testing. NIN is the national identification number, required only where listed.

Sample business data

For B2B flows, use any customer row above and set the organization number to 556131-2058. B2B purchases settle through Billie, listed under payment data below.

Sample payment data

These complete a payment inside the Kustom widget. All are playground-only.

Card

Field	Value
Credit card number	4242 4242 4242 4242
Debit card number	4000 0566 5566 5556
Card triggering 3-D Secure	4000 0027 6000 3184
CVC	123
Expiry	12/34, or any future date in MM/YY

In the United States the debit card is also what tests financing. When prompted for a Social Security Number, use 123456789.

Direct debit

Use an IBAN-format number. For a German test store, DE11 5205 1373 5120 7101 31 works. In Sweden, use the personal number 19770111-6050.

Direct bank transfer

Choose Demo Bank in the Kustom widget and follow its prompts.

Billie (B2B)

Use the organization number under sample business data above, with any customer row for the market you’re testing.

End-to-end test cases

Run these eight cases end to end in the playground before you ask for production keys, and keep them as your regression suite afterwards. They cover the four stages of the order lifecycle — purchase, pre-shipment, shipment, post-shipment — and between them exercise every money movement your integration can make. Skip any case that doesn’t apply to your store: if you never issue partial refunds, don’t test them.

#	Cart	What you do	Expected status in the Portal
1	1 item	Place, capture in full, refund in full	Fully Captured and Fully Refunded
2	2 items, added in two visits to the checkout	Place, capture in full, refund 1 item	Fully Captured and Partially Refunded
3	2 items	Place, capture 1 item, release the remaining authorization	Fully Captured
4	1 item with a discount code	Place, capture in full, refund in full	Fully Refunded, with the discount visible on the order lines
5	2 items with a gift card	Place, capture in full, refund 1 item	Fully Captured and Partially Refunded
6	1 item	Place, then cancel before capturing	Cancelled
7	1 item, different billing and shipping addresses	Place only	Order created, with two distinct addresses on the Customer panel
8	1 item plus a paid shipping option	Place only	Order created, with a shipping_fee order line

Each run follows the same shape. Add the product or products to the cart, go to the checkout, place the order with the data above and confirm you land on your confirmation page. Then open Orders in the Portal, find the order and check on the Order lines tab that product name, unit price, tax and amount are what you sent. Capture, refund, cancel or release from your own system where you have one, or from the Portal where you don’t — manual Portal steps are only reliable when your integration isn’t linked to an external system, because the Portal status won’t be synchronized with it.

Cases 2 and 4 are worth extra attention: case 2 also checks that the cart stays correct when the customer navigates between the checkout and product pages, and case 4 checks that a late discount doesn’t break tax reconciliation.

Check the order in Developer Logs

Portal statuses tell you the money moved. Developer Logs tell you the order was rich enough to be useful. Open Logs in the playground Portal, search the Kustom order id from the order’s Summary tab and check the requests against this table, with the Checkout API reference open alongside.

Order characteristic	Cases	Expected in the logs
Any placed order	1–8	order_lines entries carry product_url and image_url
A refund	1, 2, 4, 5	The response header carries the refund’s URI and id
A discount code	4	Either a separate order_line of type discount with a negative amount, or total_discount_amount set per line
A gift card	5	A separate order_line of type gift_card with a negative amount
Different billing and shipping addresses	7	billing_address and shipping_address differ, matching what you entered
A shipping fee	8	A separate order_line of type shipping_fee with the correct amount
