I'm developing a drupal site, and I chose ubercart to support our membership feature, but I've problems to let it work.
So my configuration and problem is below.
I'm using credit card
Gateway is paypal wpp.
settings for gateways is like this:
sandbox mode
complete sale
and the sandbox business account is comfirmed to be set up right.
and I think API creditial is true too.

API Credentials:
ruyang_1209890988_biz_api1.ethos.com.cn
1209890996
ANHhHe6zEZ2o.U4fMfWm9.Jsl73FAKWDy.rp5B7sCWPI0THtOtP4iS9l

I'm using a fake credit card with the CVV 000 to buy goods from my website, but I contiues to get an error: "You do not have permissions to make this API call"...
and sometimes I got the 502 proxy error, do you have any idea how to resolve this problem? Thank you so much.

I think you're going to have to get support through PayPal to figure out why they won't let your sandbox account make that API call. It can be tricky to get everything setup right.

this is the watchdog message in my drupal site:

Payment failed: Payment failed.
:
Address: An unknown error occurred.
CVV2: Not checked

why the second line is empty?

Hmm... the second line should actually have your error message from PayPal in it. I'm wondering if they've changed the API somehow. Puzzled

EDIT: I tried finding a solution to no avail... giving up for the time being to work on other stuff.
