hello vladimir , thank you for your example, the contents is for design studio, i don't find the .js attached to see what it's look like (perhaps i'm too noob to find it)

edit:  ok i find the way to edit the script attached, sorry for my poor knowledge

after a quick look, the authentication is embelded in the yahoo dialog and couldn't be setted as a template.

hello, thank you for your quick reply, i just took a look at the post mentionned, but i don't see anything complete about the exchange.

The only thing i have understood is that i have to code the entire protocole by myself on javascript document, so my next question is there anybody who have already done that ?

I so (write my onwn program) i don't now if there is a simple solution to trigger the expiration_time that should execute another program to renew the access_token with the refresh_token. Is that part also need to be developped manually by my own ?
