Thank you !
I didn't see these parameters.
I'm trying to modify my code.
To get the attached files, it's a bad news

!!!
But I see when I get answer in JSON, someting like this :
[{"title":"test","comment":"","size":"304.944","name":"Capture%20d%E2%80%99e%CC%81cran%202017-03-24%20a%CC%80%2009.03.07.png","filename":"fu_xtv8dwcdmbu8t2e","ext":"png" }]
Maybe we can acces to the file, with a secure access.....
What do you think about it ?
