Checkbox update

Checkbox update

Hello Zoho

I just created a script to update a contact profile.
Everything is okay for updating text fields, but for changing checkbox fields, i have a problem.

Here is my xml :
<Contacts> <row no="1"> <FL val="Id"> 294189000000684059 </FL> <FL val="Rejet des mails"> true </FL> </row> </Contacts>

Please note that my field isn't locked in the CRM.

Any idea ?

Best
