Paypal Sandbox Do Direct Payment Internal Error 10001 Timeout Processing Request

Question

This is in an MVC2 project, so I'm using C# in ASP. This is what I'm sending to https://api-3t.sandbox.paypal.com/nvp:

VERSION = 65.0
SIGNATURE = AFcWxV21C7fd0v3bYYYRCpSSRl31AxdW2pQp.tWHTjGNcHflR-LJhJ0t
USER = seller_1283487740_biz_api1.gmail.com
PWD = 1283487748
AMOUNT = 50.00
CREDITCARDTYPE = Visa
ACCT = 4031477440127509
EXPDATE = 12/2015
CVV2 =123
IPADDRESS = 127.0.0.1
METHOD = DoDirectPayment

I can GetBalance, I can produce other errors when I intentionally send something wrong, but DoDirectPayment or DoAuthorization returns this:

TIMESTAMP = 2010-12-24T03:35:10Z
CORRELATIONID = 2ca329fdbe3c0
ACK = Failure
L_ERRORCODE0 = 10001
L_SHORTMESSAGE0 = Internal Error
L_LONGMESSAGE0 = Timeout processing request

Why Am I getting this error?

Answer 1

Yeah, I'm getting the same thing. I tested my code on their production URL and it worked just fine.

Given how much they are focused on developers, it's amazing how horrible their API is. I can get points and follow other people on their little social network, x.com, but I CAN'T TELL WHAT THE CURRENT VERSION OF THE API IS!?!
