Unable to add new task via API - Input Parameter Missing

Unable to add new task via API - Input Parameter Missing

I'm following the spec at  http://www.zoho.com/projects/developers/tasklists-api.html#7 to Add a new task to a Project Task list - I think I have all of the required form items populated based on the provided sample,but I'm getting an error:

{"code":6831,"message":"Input Parameter missing"}

https://projectsapi.zoho.com/portal/{PortalName}/api/private/xml/task/add?apikey={ApiKey}&ticket={Ticket}

projId=f8044dc4a76d2d98e298090ee4ab5d05b3711e3d6848763c, 
personresponsible=aee2293d0f655f48, 
listId=f8044dc4a76d2d986e2974ab7fd72a8b6755b1c1035e80e0, 
todotask=Create me, 
taskdate=08-21-2012, 
pcomplete=0, 
duration=1, 
priority=None


I noticed that the documentation is inconsistent between the  Parameters to be passed and the   Sample Call

listid vs listId
percentcomplete vs pcomplete
personresponsible is show in the Sample Call but not in the Parameters to be passed.

I tried different combinations but still can't successfully create a task :-(

Could you please confirm the exact parameters required to create a task.

Thanks.

                    • Announcing the Zoho Projects API

                      Today we're excited to announce the API for Zoho Projects where any developer can extend the project management and collaboration capabilities through our APIs and can build their own customized applications for their business needs. We've tried to make the API follow the REST (Representational State Transfer) principles and generate a XML/ JSON object which allows you to access / read / write Zoho Projects data from third-party systems like Google/Yahoo gadgets, web sites, billing & invoicing systems,
                    • Have you moved to REST API?

                      Dear API Users, The Documentation of our Rest API is available here . All future development will be done to this version. We are deprecating the older API today. Its documentation will no longer be available and we will also be stopping the calls to this API soon. Thanks, Prasanna
