I'm not sure what I should add as a payload. I'm trying to get the orderhistory for my account. bittrexPrivateRequest("getorderhistory",). It keeps saying payload needs to be an object and not a string... (when I supply count=50 for example).
Edit:
I figured it out, don't call bittrexprivaterequest from within a cell, but only within the script. Add:

function bittrexGetOrderHistoryV1() {
  var results = bittrexPrivateRequest("account/getorderhistory");
  Logger.log(results);
  return json2array_(results);
};

function bittrexGetDepositAddress(currency) {
  var payload = { "currency" : currency };
  var results = bittrexPrivateRequest("account/getdepositaddress",payload);
 
  if(results.Address && results.Address != null){
    return results.Address;
  }
  else return "";
};

which you can call from within a cell

Hi, met some problems and would appreciate if you can help. The API and connection is success, but when it retrieve the balance, it also retrieve all the coins which the balance are 0. How can I filter those out. Thanks.

I feel a bit lost here I put the code in and I am use to telling it to post results to a set page. What do you put in the Dell for it to use that section

You shouldn't you just in the cell place =bittrexGetbalances and it should go out and download all your balances? Is there more to it. Please let me understand when i do this I get
Error
Unknown range name: 'BITTREXGETBALANCES'

ok so looks like
=bittrexGetbalances()
and
=bittrexGetOrderHistoryV1()

is all that working for this script am I correct. Sorry I am learning

@leejie8008 looks like it pulls everything you have a wallet on BTW

Thanks. Pretty helpful

None of you unfortunately answered, how the sheet itself can be generated? I added the keys to key sheet, but don't get any results being displayed. Please help!

Hey could somebody clarify how I would send a buy order with this code?
Ive tried:
bittrexPrivateRequest("Buy",)
but I do not know what to insert in the field "Payload".
I am aware that i have to insert the currency, the amount and the rate; but do not know in which format
Many thanks!
