Oh, that's assuming you did calculate the headers right of course - test with a balance query first.
As you can see in my original posting, I tested that.
Topic: Crypto X Change: "payload invalid" (Read 1421 times)
As you can see in my original posting, I tested that.
Have you tried emailing their support and asking instead of just posting here?
Yes, often. I get much faster replies here.
It's the order of parameters - it needs to be precisely the right order
well that's stupidYes, it is. I'm using Apache HttpClient, which doesn't let me change the order of the parameters (since their order isn't supposed to matter, I'm guessing it stores them internally in an unsorted data structure like a hash table).
What am I supposed to do, roll my own HTTP implementation just so I can trade on CryptoXChange?
Not likely.

The order of the POST parameters should not matter. Have you tried emailing their support and asking instead of just posting here?

Per the documentation here, I am sending:
POST https://cryptoxchange.com/api/v0/account/placebid/
amount=0.1&price=5.5&market=BTCUSD&stamp=1325395860020
I get back:
{
"oid":"0",
"bids":[],
"ReturnCodes":3,
"err":"payload invalid ",
"stamp":""
}
I know I'm computing the cryptokey/cryptopayload headers and "stamp" properly because I can check my balance via the API.
The message "payload invalid" is pretty unhelpful. CryptoXChange, please give more helpful error messages.
Curiously, if I omit any of the "amount", "price" or "market" fields it will complain that that field is missing instead of "payload invalid".
