[2hUI887TdKeTE]

I am unable to do payment with this Discover test credit card 6011000000000012. On clicking of Submit button I am redirecting to the same page and my cart is getting empty. Please let me know the reason of this and also let me know am I using the correct credit card. If not then please provide me the another Discover credit card for testing purpose

What cart? are you using the SDK? or you own code? what response it is returning?

And for testing it really don't matter which card you use for testing.
