We try to create a product.category from external api. 

The code was: 

$id = $models->execute_kw(oddo_db, oddo_uid, oddo_password, 'product.category', 'create', array("name"=>"hola"));

The problem is not with the connection because if I do a search it works correctly

This instruction does not create anything for me and the return value is blank and I do not get any error.

Anyone can help me?
