UK test Credit Card

I’m testing the C# Razor Sample in the UK
I have everything setup with a sandbox location in the UK I try and use the test cards but it asks for a ZIP code? (4111 1111 1111 1111)
What do I enter here to get it to process?
Can I test with UK postcode?

Thanks

At this time the test value 4111 1111 1111 1111 is a US based card which is why the Web Payments SDK is asking for a zip code. The Card payment method of the Web Payments SDK automatically infers whether to display the ZIP code, postal code, or postcode based on the issuing country of the buyer’s credit card. Depending on the card that’s used, the SDK automatically removes the postal code if the card’s issuing country doesn’t require the postal code for the payment. If you use the test value 5248 4800 0021 0026 it will show Postcode. :slightly_smiling_face:
