Can you somehow configure a test account in the PayPal Sandbox testing environment to return a credit card declined failure message when that user tries to submit a payment or trigger a failure message on an individual transaction?
I've looked around on the Internet for way to do this, and some of the suggested solutions included:
- Altering the test user account address to trigger address verification failure (which did not work, but it was seven-year-old documentation).
- Turn on negative testing and fire off requests to the sandbox to get a failure message according to the amount you send in (which won't work for me, as I'm trying to test this from the user's perspective by creating the transaction through the Web site and submitting for PayPal payment, and seeing how the system processes the response).
- Submitting a transaction over $1000 (which won't work as our transactions do not exceed $100 in value).
I know you can fail an eCheck payment while it's pending, but I don't see any way to do the same with credit card payments. Is there a means?
