Updated in 4.93 You can customize the Webchat widget by adding plugins. Find Webchat plugins in the [plugin collection](https://github.com/Cognigy/WebchatPlugins/tree/master) on GitHub or create your own custom plugins. You can implement plugins in: * [The Demo Webchat](#test-plugins-in-demo-webchat) — test plugins from the collection by using the Webchat Endpoint settings. * [In your code](#set-up-plugins-in-your-code) — add custom plugins or plugins from the collection to the Webchat widget in your website. After setting them up, you need to [trigger them in the Flow editor](#trigger-plugins). Plugins created for Webchat v2 are compatible with Webchat v3 but may display a different styling. ## Test Plugins in Demo Webchat To test a plugin from the plugin collection, follow these steps: 1. Open the [Cognigy GitHub repository](https://github.com/Cognigy/WebchatPlugins/tree/master) and select the plugin you want to use. 2. On the [Releases](https://github.com/Cognigy/WebchatPlugins/releases) page, copy the URL of the JavaScript file from the **Assets** section of the plugin you selected. For example, the URL for the Google Firebase Authentication Webchat Plugin is `https://github.com/Cognigy/WebchatPlugins/releases/download/google-firebase-authentication100/google-firebase-authentication.webchat-plugin.js`. 3. In Cognigy.AI, select a Project from the Projects list. 4. In **Deploy > Endpoints**, select an Endpoint or create a new one: 1) Select the **Webchat (v3)** Endpoint. 2) In the Webchat v3 Endpoint settings, paste the URL into the **Webchat Plugins** field under the **Demo Webchat Settings** section. 1. Select the **Webchat** Endpoint. 2. In the Webchat Endpoint settings, paste the URL into the **Webchat Plugins** field under the **Webchat Layout** section. ## Set Up Plugins in Your Code You can set up plugins in your code in the embedding code of your [Webchat v3](/webchat/v3/embedding/hosted-script) or [Webchat v2](/webchat/v2/embedding). To add the plugins in your code, proceed as follows: 1. Open the [Cognigy GitHub repository](https://github.com/Cognigy/WebchatPlugins/tree/master) and select the plugin you want to use. 2. On the [Releases](https://github.com/Cognigy/WebchatPlugins/releases) page, copy the URL of the JavaScript file from the **Assets** section of the plugin you selected. For example, the URL for the Google Firebase Authentication Webchat Plugin is `https://github.com/Cognigy/WebchatPlugins/releases/download/google-firebase-authentication100/google-firebase-authentication.webchat-plugin.js`. 3. Add the plugin using a ` ``` 1. Open the [Cognigy GitHub repository](https://github.com/Cognigy/WebchatPlugins/tree/master). 2. Clone and modify the plugin source code as needed. 3. Build your plugin by running the `npm ci && npm run build` command. 4. Upload your plugin to your cloud storage, for example, Amazon S3. Ensure that the uploaded plugin is accessible to the target audience. Check the availability settings on your cloud storage side. 5. Enter the plugin URL in a ` ``` ## Trigger Plugins Most plugins based on [Cognigy plugin examples](https://github.com/Cognigy/WebchatPlugins/blob/master/examples/) are activated only when specific data is present in a message. The plugin code specifies the `"match": "plugin-name"` condition, which determines when the plugin is triggered. For example, the `"match": "dialog"` condition triggers the plugin when the message contains the word `dialog`. See the [source code](https://github.com/Cognigy/WebchatPlugins/blob/4b472973d94748e93e69d06f0450b2004a428c9a/examples/dialog-example/src/index.jsx#L97). For instance, consider a plugin that displays images in a chat interface, extracting the URL from the message's data. This plugin has two parameters: `match` set to `inline-image`, and `url` which retrieves the image URL from `message.data._plugin.url`. When Webchat receives a message, it triggers the `inline-image` plugin if the condition `message.data._plugin.type === 'inline-image'` is met. Then, the plugin retrieves the image URL from `message.data._plugin.url`. You can trigger plugins using the following components: * [Basic Nodes](#basic-nodes) * [Code Node](#code-node) * [Extensions](#extensions) ### Basic Nodes 1. In the Node Editor, navigate to the **Options** section. 2. In the **Data** field, enter the following JSON to trigger the plugin. Example: ```JSON theme={null} { "_plugin": { "type": "inline-image", "url": "https://placekitten.com/256/256" } } ``` #### Code Node 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. Example: ```js theme={null} api.output('' , { _plugin: { type: "inline-image", url: "https://placekitten.com/256/256" } }) ``` ### Extensions You can build an [Extension](/ai/for-developers/extensions) that sends a message triggering the Webchat plugin, simplifying the process to only include the necessary parameters. Custom module example: ```js theme={null} /** * 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.api.output('', { _plugin: { type: "inline-image", url: "https://placekitten.com/256/256" } }); return input; } ``` ## More Information * [Webchat v3](/webchat/v3/overview) * [Webchat v2](/webchat/v2/overview)
