[8.1.0] Webservice filters on't seem to work?

[SparkyRih]

I have written a .NET application which communicates with my PrestaShop webshop. I developed this application for 1.5.x a long time ago.

Now I started working on a new version for 8.0.1, but due to lack of time didn't finish it.

I recently upgrade my webshop to 8.1.0, and started working on the .NET application again, but the filters don't seem to work anymore... I did not make any changes in my application, just fired it up...

 

This is an example of a URL which is used to obtain the products for a specific category:

`https://<url>/api/products?filter[id_category_default]=[10]filter[available_for_order]=[1]filter[active]=[1]filter[online_only]=[0]&display=full`

It just returns all my products (also the inactive ones). When I remove the `&display=full` parameter, it just returns nothing.

 

Even this one, just returns all categories, instead of just (in my case) 3 main categories:

`https://<url>/api/categories/filter[id_parent]=[2]&display=full`

 

Is this a bug, or has something changed in the API (I cannot find Qanything about that in the documentation).
