Hi,  
The documentation doesn’t talk about filters on collections (or in general for that matter)?  
[https://getcockpit.com/documentation/api/collections](https://getcockpit.com/documentation/api/collections)

I am trying to build a wiki using Cockpit (thanks @artur for sharing this project). I want to listCollections but only those matching Group: wiki (or any other alternative).

Possible or not?  
Thanks!

It’s not possible by default, but you can write your own api endpoint and return the filterered collections. Create a file in `/cockpit/config/api/collections/myOwnEndpoint.php`

```php
$collections = $this->module('collections')->getCollectionsInGroup();
// check the array
return $collections;

```

That’s the original function:

@raffaelj Thank you so much for replying so fast! I was looking at this method too (in RestApi.php) and I was wondering if it was possible to use the getCollectionsInGroup (as user)?

I’m not quite sure, what you mean. The function `getCollectionsInGroup()` returns only collections with the user group permissions. But if you don’t care about user groups, than do

```php
<?php
$collections = $this->module('collections')->collections();
$filtered = [];
foreach($collections as $collection) {
    if (isset($collection['group'] && $collection['group'] == 'wiki') {
        $filtered[] = $collection;
    }
}

```

or something similar.
