$response

This object is used for filling in system responses.

$response.replies is a list of responses made while processing chatbot reactions. It is an array containing strictly typed elements and utilized in order to transfer chatbot replies to platform-specific chat adapters, such as Telegram, Google Assistant, etc.

replies supports objects of the following types:

• text is a regular text response. Every element of this type is printed out as a separate message. The tts parameter should contain the same text with special markup rendered by speech synthesis systems. The markup parameter determines text formatting style.

{
    "type": "text",
    "text": "....",
    "tts": "....",
    "markup": "html|markdown|plain"
}

• buttons — renders a regular button.

{
    "type": "buttons",
    "buttons": [
        {
            "text": "button" // All the remaining attributes will be directly passed on to the messenger.
        }
    ]
}

• inlineButtons — renders an inline button. If a url attribute is present, then the specified link will be opened upon pressing the button.

{
    "type": "inlineButtons",
    "buttons": [
        {
            "text": "button",
            "url": "https://example.com"
        }
    ]
}

• image — renders an image.

{
    "type": "image",
    "imageUrl": "http://..."
}

• raw — is used for passing on methods specific to a particular channel. The mandatory body parameter contains the response body transferred into the chat system. Parameters used for user identification are set up automatically.

{
    "type": "raw",
    "body": {...},
    "method": "sendMessage"
}

• switch — switches the dialog from the bot to a customer service agent.

{
    "type": "switch",
    "firstMessage": "...",
    "closeChatPhrases": ["..."],
    "ignoreOffline":true|false,
    "oneTimeMessage": true|false
}

• location — prints out geographic coordinates. Its attributes are lat and lon.

{
    "type": "location",
    "lat": 59.934280,
    "lon": 30.335099
}

• timeout — makes a transition to a specified state if the user gives no response.

{
    "type": "timeout",
    "interval": 10,
    "targetState": "/timedout"
}

• dtmf — is a DTMF message signal (containing figures and characters typed on a touch-tone keypad). Intended for calls only.

script:
    $response.replies.push({
        type: "image",
        imageUrl: "https://testimageurl.jpg",
        text: "Image" // This field is optional.
    });

$response.replies = $response.replies || [];
$response.replies .push({

    closeChatPhrases: catchAll.closeChatPhrases,
    firstMessage: $client.history,

});

• Changing the reply in the post-process if the bot tries to give the same reply for the third time in a row.

init:
    bind("postProcess", function(){
        var $session = $jsapi.context().session;
        var $response = $jsapi.context().response;
        var answer = $response.replies ? $response.replies.reduce (function (answers, current) {
            answers += " " + current.text;
            return answers;
        }, "")  : "";
        if ($session.lastAnswer && (answer == $session.lastAnswer)) {
            $session.answerRepetition = $session.answerRepetition || 0;
            $session.answerRepetition += 1;
        } else {
            $session.answerRepetition = 0;
        }
        if ($session.answerRepetition == 2) {
            $response.replies = [{
                "type": "text",
                "text": "We are going in circles. Could you ask me something else?"
            }];
        }
        $session.lastAnswer = answer;
    });
