Action

An action contains the business logic to handle a request and produce a response. Fusio contains already many actions for common tasks i.e. to execute database operations or push data to a message queue.

Async​

It is possible to execute an action in async mode which means that the action directly returns a 202 accepted response and the request gets executed later on in the background. To enable the async feature you need to setup a cronjob, please take a look at the cronjob section for installation instructions.

Development​

To develop a custom action you need to create a class which implements the interface Fusio\Engine\ActionInterface. Then you can add this class to the provider.php file. Through this it is possible to select this action at the backend. Beside selecting an action you can also click on the edit button to manually enter a class name.

In the following an example action:

<?php

namespace App\Action;

use Fusio\Engine\ActionAbstract;
use Fusio\Engine\ContextInterface;
use Fusio\Engine\ParametersInterface;
use Fusio\Engine\RequestInterface;

class HelloWorld extends ActionAbstract
{
    public function handle(RequestInterface $request, ParametersInterface $configuration, ContextInterface $context): mixed
    {
        return $this->response->build(200, [], [
            'hello' => 'world'
        ]);
    }
}

If you add a constructor to your action Fusio will try to resolve the dependencies based on the DI container.
