Action

An action contains the business logic of your API endpoint. Fusio provides out of the box predefined actions which handle common tasks like selecting data from a table or proxy a request to an internal API. You can discover all existing actions at the action index.

Worker​

Besides these available actions which can be configured Fusio provides Worker actions which allow you to specify the action logic directly at the backend using a specific programming language. These worker actions can be used to implement custom backend logic.

The following pages provide a first insight how you can solve common tasks.

Take a look at the PHP API for a complete reference of the internal API.

Development​

Internally every action is always a PHP class which handles the actual logic. Instead of using the Worker actions you can also directly implement your action as PHP class which implements an ActionInterface. Take a look at the custom action guide, this is intended for developers who like to build OOP systems using PHP classes and dependency injection.
