How to withdraw dollars from MtGox to dwolla?

Question

I am trying to use the following API to withdraw dollars from MtGox to DWOLLA. The code I already implemented successfully handles authentication. From the write-up it seems to me that I need to post something like that:

group1=DWUSD&btca=XXX-XXX-XXXX&amount=XXX.XX

However, I'm getting an error in response, which says:

{"error":"Amount too low or invalid Dwolla account"}

Anyone here has an idea what the proper calling convention is? I am a little hesitant to play around, fear the money will get lost if I do something incorrect.

Answer 1

I found the resolution by examining HTML on MtGox site. Must use dwaccount= instead of btca= when withdrawing to dwolla
