Each user can choose his own data source => is a service provider relevant ?

In your scenario, using a service provider can be a relevant and effective approach, especially if you're working within a framework like Laravel that supports service providers. Here's how you can structure your solution:

Define the Interface: You already have a DataSourceInterface. This is a good start as it defines the contract that all data source services must adhere to.
```
interface DataSourceInterface {
    public function fetchData();
    // Add other methods as needed
}
```

Implement the Interface: Create classes for each data source that implement this interface.

class PipedriveDataService implements DataSourceInterface {
    public function fetchData() {
        // Implementation for fetching data from Pipedrive
    }
}

class GoogleSheetDataService implements DataSourceInterface {
    public function fetchData() {
        // Implementation for fetching data from Google Sheets
    }
}

Use a Service Provider: In Laravel, a service provider can be used to bind the interface to a specific implementation based on the user's choice. This is where the service provider becomes relevant.

use Illuminate\Support\ServiceProvider;

class DataSourceServiceProvider extends ServiceProvider {
    public function register() {
        $this->app->singleton(DataSourceInterface::class, function ($app) {
            // Logic to determine which data source to use
            $user = auth()->user();
            $dataSource = $user->preferred_data_source; // Assume this is stored in the user's profile

            switch ($dataSource) {
                case 'pipedrive':
                    return new PipedriveDataService();
                case 'googlesheet':
                    return new GoogleSheetDataService();
                // Add more cases as needed
                default:
                    throw new \Exception("Unsupported data source");
            }
        });
    }
}

Register the Service Provider: Ensure that your service provider is registered in the config/app.php file under the providers array.

Use Dependency Injection: Now, wherever you need to use the data source, you can inject the DataSourceInterface.

class SomeController extends Controller {
    protected $dataSource;

    public function __construct(DataSourceInterface $dataSource) {
        $this->dataSource = $dataSource;
    }

    public function index() {
        $data = $this->dataSource->fetchData();
        // Use the data as needed
    }
}

By using a service provider, you can dynamically resolve the correct data source service based on the user's choice, making your application flexible and scalable as you add more data sources in the future.
