You would probably need to make your own middleware script to request from cockpit, filter, and return.

You do not need a middleware… You can just create api endpoints (which are reflected onto a php-script) a very simple way:

- [How to create custom API Endpoints - #5 by artur](https://discourse.getcockpit.com/t/how-to-create-custom-api-endpoints/202/5)
- A small but concrete example:
  - [How to get quantity number of my entries - #3 by raffaelj](https://discourse.getcockpit.com/t/how-to-get-quantity-number-of-my-entries/1361/3)
  - =\> [cockpit-scripts/count.php at master · raffaelj/cockpit-scripts · GitHub](https://github.com/raffaelj/cockpit-scripts/blob/master/custom-api-endpoints/count.php)

Ok. Thank you! I will try, although I am not php developer 🙂  
I thought it configurable in the cockpit.

Ok. Thanks for modest answer 🙂 I thought, it can be filtering inside “fields” POST body. For example:  
{  
“fields”: {  
“active”: 0,  
“tests.active”: 0  
or  
“tests”: {  
“active”: 0  
}  
},  
“populate”: 1  
}
