Rest API Zimbra 8

Hello,
I am French I ask you to forgive my use of the English ...

I try to wear my Zimlet (version 7) to Zimbra 8.

I have no problems until I try to export an email with the Rest API.

Here is what I did in Zimbra 7 and does not work on Zimbra 8:

https://serveurZimbra/home/ ~ /? id = 356 (356 is the identifier of the Zimbra mail export.)

I get this error:



Unfortunately I can not find the API documentation for zimbra 8.

Sincerely,
aetuo
