Hi

I am trying to insert a lead. I am following the examples, even using the same xml. 


Here is the xml I am using (it probably looks familiar);

  2. <Leads>
  3. <row no="1">
  4. <FL val="Lead Source">Web Download</FL>
  5. <FL val="Company">Your Company</FL>
  6. <FL val="First Name">Hannah</FL>
  7. <FL val="Last Name">Smith</FL>
  8. <FL val="Email">testing@testing.com</FL>
  9. <FL val="Title">Manager</FL>
  10. <FL val="Phone">1234567890</FL>
  11. <FL val="Home Phone">0987654321</FL>
  12. <FL val="Other Phone">1212211212</FL>
  13. <FL val="Fax">02927272626</FL>
  14. <FL val="Mobile">292827622</FL>
  15. </row>
  16. </Leads>
And here is the POST url I am using (with token obfuscated):
https://crm.zoho.com/crm/private/xml/Leads/insertRecords?authtoken=qwerty23423423&scope=crmapi


I can use the getRecords method, and it works, so I know the token is correct.

What could be wrong?
