Getting Notes from CRM

Hello, I am new to Zoho, so my question may have been answered, but I cant find anything. I am trying to do a getrecords for Notes. I keep having an error. See below

{"response":{"error":{"code":"4600","message":"Unable to process your request. Please verify whether you have entered proper method name,parameter and parameter values."},"uri":"/crm/private/json/Notes/getRecords"}}

Can anyone please point me to the solution?

Thank you.
