Can I add organization information into Saasu from Zoho-Creator?

I have an account in Saasu. And also have an account in Zoho.

I created an application in Zoho-Creator. In that application I am trying to insert new Organization records in the Saasu account.
How can I do this?

I have the webservice key and fileId of Saasu.

Can any one help me?
