Cognigy.AI Docs

COGNIGY.AI is the Conversational AI Platform focused on the needs of large enterprises to develop, deploy and run Conversational AI’s on any conversational channel.

Given the arising need of voice interfaces as the most natural way of communicating with brands, Cognigy was founded in 2016 by Sascha Poggemann and Phil Heltewig. Our mission: to enable all devices and applications to intelligently communicate with their users via naturally spoken or written dialogue.

Triggering Webchat Plugins


Many Plugins (e.g. those who use a string as the match value) will only be triggered whenever a message contains specific data.

As an example, let's imagine we have a plugin that displays images in the chat, taking the url from the message's data.
The match field is set to inline-image and it reads the image url from
In order to trigger the plugin, we would need to send a message with the data field set up like this:

  "_plugin": {
    "type": "inline-image",
    "url": ""

When the webchat receives this mesage, it will trigger the inline-image-plugin because of === 'inline-image'. The plugin itself then reads the url from

Usage within regular Flow Nodes

Using regular Flow Nodes (such as the Say Node), you can make use of the data field in order to append a data payload to a message. The Data Field will help you with syntax highlighting to prevent structural errors.

Usage within Code Nodes

If you prefer using a Code Node to send a message, you can pass the structured data payload as a second parameter to the actions.output method.

Usage within Extensions

To get the best user experience for the editors of a Conversational AI, you can build a customized Extension that sends a message triggering the webchat plugin, abstracting away everything but the required parameters.

 * Sends an Image to the user via webchat
 * @arg {CognigyScript} `url` The url of the image
const sendInlineImage = async (input, args) => {
    const { url } = args;

    // if no url is set
    if (!url) {
        // do nothing
        return input;

    // send a message that triggers the 'inline-image' plugin with a url
    input.actions.output('', {
        _plugin: {
            type: "inline-image",
            url: ""

    return input;
