Where can I get this variables?

• Login at https://dialogflow.cloud.google.com/
• Create NewAgent (or use an existing one)
• Click on "Settings" icon (1)
• Copy your project id (2) into .env file
• Click on project id (2)

• After that you will find "Service accounts" section (click (1) or (2))

• Click on "Create service account", fill "name" field and click "Create"

• On the next step you have to add two roles, "DialogFlow API Admin" and "DialogFlow API Client" and click "Done"

• Now, go to the page "Manage keys"

• Create new key in .json format

• Move downloaded file into project root directory
• Add path to file in .env

Code example

$dialogflow = \BotMan\Middleware\DialogFlow\V2\DialogFlow::create('en');
$botman->middleware->received($dialogflow);
$botman->hears('smalltalk.(.*)', function ($bot) {
    $extras = $bot->getMessage()->getExtras();
    $bot->reply($extras['apiReply']);
})->middleware($dialogflow);

smalltalk.(.*) - there is action name pattern

If you create actions with different prefixes, you can use ->ignoreIntentPattern()

$dialogflow = DialogFlow::create('en')->ignoreIntentPattern();
