upload a pdf file using XML

upload a pdf file using XML

I'm trying to upload a PDF that's hosted on our server, but for the life of me I can't figure this thing out! Please help!

I see that it can be done with the uploadFile Method, but "agreementURL" only attaches a link to the file. The URL doesn't seem to work with "Content". What exactly do I need to enter for the File Input Stream?

https://crm.zoho.com/crm/private/xml/Potentials/uploadFile?authtoken=[auth_token]&scope=crmapi&id=[potential_ID]&content= http://www.[MY_URL].pdf


Or is there an easy way to do it with the updateRecords or insertRecords methods... ie:

https://crm.zoho.com/crm/private/xml/Potentials/updateRecords?authtoken=[auth_token]&scope=crmapi&id=[potential_ID]&xmlData=<Potentials><row no="1"><FL val="Attachment"> http://www.motifator.com/storage/support/motifese1.pdf</FL></row></Potentials>
