Module APIs

The folder /docs/htmlcontains HTML rendered documentations for all available API endpoints.

Swagger / OpenAPI 3.0.0

You can find Swagger documentation files in the /docs/swagger directory of this module.


/docs/postman contains a PostMan collection with all available requests.

API development


To completely adapt the API documentation after a change, the following steps are necessary.


The Swagger documentation is located in the folder /docs/swagger, you need to rebuild the html documentation at /docs/html which is based on the Swagger YAML files.

To create a HTML documentation you need to install the redoc-cli NPM package.

Build HTML documentation:

cd docs/swagger


Also add examples to the PostMan API request collection located in the folder: /docs/postman.

Other module support

To append endpoints from another module:

1) Add event in the file config.php of your module the following line:

['class' => 'humhub\modules\rest\Module', 'event' => 'restApiAddRules', 'callback' => ['humhub\modules\your_module\Events', 'onRestApiAddRules']],

2) Implement humhub\modules\your_module\Events::onRestApiAddRules like this:

public static function onRestApiAddRules()
    /* @var humhub\modules\rest\Module $restModule */
    $restModule = Yii::$app->getModule('rest');
        ['pattern' => 'your_module/<objectId:\d+>/user/<userId:\d+>', 'route' => 'your_module/rest/user/add', 'verb' => 'POST'],

3) Create a new controller, for example, here protected/modules/your_module/controllers/rest/UserController.php:

namespace humhub\modules\your_module\controllers\rest;

use humhub\modules\rest\components\BaseController;

class UserController extends BaseController
    public function actionAdd($messageId, $userId)
        return [...];

4) Modify your module initialization in order to avoid errors on CLI mode:

public function init()

    if (Yii::$app instanceof \humhub\components\console\Application) {
        // Prevents the Yii HelpCommand from crawling all web controllers and possibly throwing errors at REST endpoints if the REST module is not available.
        $this->controllerNamespace = 'your_module/commands';
