Create Order Request Body

[unk1911]

thanks, that was precisely the issue. once i wrapped the numeric values as strings, i was able to create the order. this is the JSON that worked:

{ 
  "client_order_id": "6556d745-7c3a-4a1e-8f41-623b51beb269", 
  "product_id": "BTC-USD", 
  "side":  "BUY", 
  "order_configuration": {  
        "limit_limit_gtc": {  
             "base_size": "0.01",  
             "limit_price": "15000.0",  
             "post_only": false  
        }  
  }  
}
