So when I try to use the API method to insertRecords for potentials it uploaded all but a few and after much playing around it appears that the reason why they didn't upload (had error 500) was because I had a & (ampersand) in my account name. So i tried the html escape squance of %26 and that didn't work. Example would be

 

<Potentials><row val="1"><FL val="Account Name">AT&T</FL></row></Potentials>. If i send that I get a error 500. if I use the escape squence %26

 

<Potentials><row val="1"><FL val="Account Name">AT%26T</FL></row></Potentials>.

 

Zoho saves my Account Name as "AT%26T" and not AT&T. So how do I post it with a &?
