Issue with the Zoho Project API

Issue with the Zoho Project API

I am issuing a Get all Activities request at the URL  http://projects.zoho.com/portal/{myporta}/api/private/xml/dashb?[mydata]

and receiving an error code 6501 - 'inpurt parameter doesn't match'

The parameters I am sending are:
"projId": [valid id],
"auditIndex": "",
"range": "",
"username": "all"

Is there a reason this is wrong?

Additionally, the get milestone request fails for requests where flag = 'allflag' but works for 'external' and internal.


Can this be fixed?  Am I doing something wrong?
