Request using Curl (Windows 10) in Matlab gives error message

I am sending a curl command to a server, but get an error message which I do not understand.



The request I need to send to the server is



body=$(cat << EOF
{
"order": {
"units": "100",
"instrument": "EUR_USD",
"timeInForce": "FOK",
"type": "MARKET",
"positionFill": "DEFAULT"
}
}
EOF
)

curl
-X POST
-H "Content-Type: application/json"
-H "Authorization: Bearer TOKEN>"
-d "$body"
"https://api-fxtrade.oanda.com/v3/accounts/<ACCOUNT>/orders"


What I do is that I translate this into a curl command like :



curlcmd = 'curl -s -X POST -H "Content-Type: application/json" -H "Authorization: Bearer " -d "{"order": {"units": "100", "instrument": "EUR_USD", "timeInForce": "FOK", "type": "MARKET", "positionFill": "DEFAULT" }}" "https://api-fxpractice.oanda.com/v3/accounts/AccountID/orders"'



I send the command via resp = system (curlcmd) via Matlab to the server. What I get as an error message is :



errorMessage: 'Invalid JSON, ParseErrorCode: 4, Message: Missing a name for object member.'



Any idea what this means and how I can solve this ? I am using Matlab on Windows 10, so curl is part of Windows 10.



Response should be a placed order and response data of the trade.

          The JSON doesn't seem to be properly quoted.



          Try this:



          curl -s -X POST -H "Content-Type: application/json" -H "Authorization: Bearer " -d "{"order": {"units": "100", "instrument": "EUR_USD", "timeInForce": "FOK", "type": "MARKET", "positionFill": "DEFAULT" }}" "https://api-fxpractice.oanda.com/v3/accounts/AccountID/orders" 


          Test with Proxy



          With the appropriate escape of the JSON quotes, as shown in the above CURL command line, the JSON looks correct when viewed in an HTTPS proxy:
