Braintree - Failed payment looks like the order completed successfully.

[angelleye]

Reported by our PayPal rep certifying our Braintree integration.

I think I found a case where a decline was being treated as a successful transaction. Here are the steps to reproduce:

o Link a PayPal Sandbox account to your Braintree Sandbox account. (If you don’t have this set up, let me know – I can help you with that.)

o On the PayPal Sandbox account, enable Payment Review (from https://developer.paypal.com -- if you don’t know how to do this, let me know – I can help you with that.)

o In the WooCommerce plugin, enable the drop-in UI.

o On the checkout page, click the PayPal button and go through the PayPal checkout.

o Click “Place Order”. The order is accepted, even though Braintree sends back a “2081: PayPal pending payments are not supported” error.

o Here’s what I see as a buyer:

Here is what I see in the WooCommerce checkout when completed.

Here is what Braintree admin panel shows for the transaction...

Here is what the log shows...

Follow up from PayPal rep...

· On the first attempt, I saw two full Braintree payment forms. (One disappeared when I completed the PayPal checkout.)

· On the second attempt, I wasn’t watching – I don’t know what happened there.

· On the third attempt, I saw two “loading” spinners come up (one right below the other). One disappeared before it was able to load completely.

I set up a copy on my personal server (external to PayPal); on that one, this is what I’m seeing:
· Spinner pops up

· Payment form pops up

· Payment form disappears

· Another spinner pops up

· Another payment form pops up
