How to add document in DocuSign

I have following request to be sent to DocuSign API,

"emailSubject": 'DocuSign API - Signature Request on Document Call',
                    "documents": [{
                        "name": test.pdf,
                        "documentId": 1,
                    }]

What I dont understand is, where should the documents name be present and what about the documentId.

I got an error as follows:

{ errorCode: 'INVALID_REQUEST_PARAMETER',
  message: 'The request contained at least one invalid parameter. A document was defined without setting the \'name\' field.' }
Error calling webservice, status is:  400

I think it cannot find the pdf.
