I'm trying to learn the yodlee developer portal. I have signed up and now going the the Getting Started at the cobrand login. I have tried to do the request like they have in the documentation. What is the correct way to get the cobrand context with the correct params?

➜  perceptor git:(develop) http -f POST https://developer.api.yodlee.com/ysl/restserver/v1/cobrand/login cobrandLogin=sbCobxxxxxxxxxx cobrancdPassword=xxxxxxxxx-xxxxxxxx-xxxxxxxx-xxxxxxxxxx 

HTTP/1.1 401 Unauthorized
Content-Encoding: gzip
Content-Type: application/json;charset=UTF-8

{
    "errorCode": "Y001", 
    "errorMessage": "loginName and password required", 
    "referenceCode": "u1497123885399Y4O27X"
}

Afterwards I thought maybe the params were named wrong and tried changing them but that really does come back as a Bad Request.

➜  perceptor git:(develop) http -f POST 
cobrandLogin=sbCobxxxxxxxxxx cobrancdPassword=xxxxxxxxx-xxxxxxxx-xxxxxxxx-xxxxxxxxxx

Updated info

I was able to get cobrand login to work following @Krithik advice on the json structure.

{ "cobrand": 
    { 
        "cobrandLogin": "xxxxxxxxxxxxx", 
        "cobrandPassword": "xxxxxxxxx-xxxxxxxx-xxxxxxxxxx-xxxxxxx", 
        "locale": "en_US"
    }
}

I am still having trouble finishing the user login portion. I am trying to run this. With the $COBRAND=Authorization: {cobrandSession=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx} and a json structure.

{
    "cobrandName": "Name of the cobrand",
    "loginName": "sbMemxxxxxxxxxxxxxxx", 
    "password": "xxxxxxxxxxxxxxxxxxxx"
}

}

Update Again

Changing the user login structure as below will be a successful login.

{
    "user":
    {
        "cobrandName": "Name of the cobrand",
        "loginName": "sbMemxxxxxxxxxxxxx", 
        "password": "xxxxxxxxxxxxxxx"
    }
}

Please do a cobrand login using-

{ "cobrand": { "cobrandLogin": "xxxxxxxxxxxx", "cobrandPassword": "xxxxxxxxxxxx", "locale": "en_US" } }

CURL command:

curl -X POST \ URL/v1/cobrand/login \

-d '{ "cobrand": { "cobrandLogin": "xxxxxxxxxxxxxxxxx", "cobrandPassword": "xxxxxxxxxxxxxxx", "locale": "en_US" } }'

Hope this helps.
