I'm trying to use zoho api to synchronize our client in zoho CRM.

We created custom fields.

When i try to update a lead some custom fields are not taken in account

Some are working fine, but most doesn't

I don't know where i can find the name of the field to add it in the object send to zoho

For example :  

custom attribute name : ID JRDM

name of the parameter : id_jrdm

=> work fine

=> doesn't work

I try to make a external form to watch param value

For "Nombre connexions" the name of the param is "LEADCF52"

I try this name param in my ruby script but it's still not working (try "LEADCF52" and "leadcf52")

Any idea about what is wrong ?

Someting in the api ? Or in the ruby gem ?

Thanks
