v1, "Missing or empty parameters:" when using `addOrder`

[GalGreenfield]

Hello,

I'm trying to use the addOrder method of the following data:

• URL: https://api.coinigy.com/api/v1/addOrder

• Content-Type: application/json
  X-API-KEY: <my_api_key>
  X-API-SECRET: <my_api_secret>
  

• auth_id: 332719,
  exch_id: 15,
  mkt_id: 5110,
  order_type_id: 2,
  price_type_id: 3,
  limit_price: 5678,
  order_quantity: 1
  

And I'm getting the error:

"Missing or empty parameters:"

The full response is:

{
 "error_num": "1057-33-01"
 "err_msg": "Missing or empty parameters"
}

without any parameter stated.
I don't know if there's anything wrong with my request.
All the data that I inserted to it seems to me like it shouldn't make the request unacceptable by your API.

Can someone please help me?

Similar issue here.
using in my API call:
values = json.dumps({'exchange_code': exchange[1]})
to get markets works perfectly, but:
values = json.dumps({ 'exchange_code': exchange[1], 'exchange_market': market[2], 'type': 'history' }).encode('utf-8')
to get market_data history returns:
{u'err_msg': u'Missing or empty parameters:', u'err_num': u'1057-14-01'}
but if I print values I get:
{"exchange_market": "XRP/USD", "type": "history", "exchange_code": "BITS"}
can someone help me here..
I also tried to remove the json.dumps() function with same result.
Thank you for your help.

NOTE: obviously that exchange and market variables return exch_name and mkt_name.

Solved it.
The problem was that I was creating a dictionary that didn't fit the required parameters, that hold the correct one dict. By expand this dictionary parameters fit.
Sorry for the inconvenience.
