Statistic count not working with API call There isn't much info around it, but when I'm using Statistic module to get the views per node it's only working when I'm visiting the page of the specific node. When I'm using an API call to a specific node, the statistic module doesn't increase with 1...

Is there a way to solve this?
Node views are only counted when node_view() is invoked (i.e. when the node is actually viewed).

When retrieving a node via services you're not, conceptually, "viewing" it, so you shouldn't expect the view count to increase.

In order to get your desired workflow, you'll probably need to implement a custom services resource which updates the statistics manually when a node object is requested. See How to create a custom resource with Services-3.x for more info.
