API - List order with filter DATE_ADD

[LMPG]

Hello,

 

I have a problem retrieving orders from a specific date in PHP using this :

 

$opt = array(

'resource' => 'orders',

'display' => 'full',

'filter[date_add]' => '[2017-01-16,2017-01-17]',

'date' => '1'

);

 

When I remove the filter, my script is working, but not with the filter "date_add".

I've been looking everywere for 2 days without finding any answer

 

If I use the same filter in an URL : myshop/api/orders?filter[date_add]='[2017-01-16,2017-01-17]&date=1 it's working
