+# jambonz Node.js SDK
+
+The jambonz Node.js SDK is one of the simplest and most powerful ways to build jambonz applications.  
+
+The video below provides a walk-through of how to create an application using the [create-jambonz-app](/docs/client-sdks/create-jambonz-app) utility, and then gives examples of building various webhooks applications that include collecting speech or dtmf input as well as integration with Google [Dialogflow](https://developers.google.com/learn/pathways/chatbots-dialogflow) and AWS [Lex V2](https://aws.amazon.com/blogs/aws/amazon-lex-enhanced-console-experience/).

+
+#### Up and running
+As mentioned above, the [create-jambonz-app](/docs/client-sdks/create-jambonz-app) will scaffold you an [express](https://expressjs.com/)-based app that provides a great starting point.
+
+If you prefer to use a different http server, or you need to integrate the jambonz webhooks into an existing Node.js application, then you simply need to install [@jambonz/node-client](https://www.npmjs.com/package/@jambonz/node-client) in your application.
+
+```bash
+npm install --save @jambonz/node-client
+```
+
+If your application just needs to respond to [webhooks](/docs/webhooks/overview/), you can include it like this:
+```js
+const {WebhookResponse} = require('@jambonz/node-client');
+```
+
+If your application also needs to make [REST API calls](/docs/rest/overview/), you can include it like this:
+```js
+const jambonz = require('@jambonz/node-client');
+const {WebhookResponse} = jambonz;
+const client = jambonz('your-account-sid', 'your-api-key', {baseUrl: 'https://jambonz.us'});
+```
+> Note: if you are running a self-hosted system, replace `https://jambonz.us` in the above with the appropriate URL of your own jambonz system.
+
+#### How to use it - Webhooks
+Responding to webhooks is quite simple:
+
+```js
+router.post('/', (req, res) => {
+  const app = new WebhookResponse();
+  app
+    .pause({length: 1.5})
+    .say({
+      text 'hi there, and welcome to jambonz!'
+    });
+  res.status(200).json(app);
+```
+
+The WebhookResponse instance offers methods corresponding to each of the [jambonz verbs](/docs/webhooks/overview/), so for the example above you can see the possible options for the `pause` verb [here](/docs/webhooks/pause/), and for the `say` verb [here](/docs/webhooks/say/).  After adding all of the verbs that you want to execute, in the order that you want them to happen, simply return the `app` object in the 200 OK to the HTTP request.
+
+
+#### How to use it - REST API
+To making a REST API call simply use the `client` object we showed how to create earlier:
+```js
+await client.calls.update(req.body.call_sid, {mute_status: 'mute'});
+```
+Documentation for the REST API can be found [here](/docs/rest/overview/).
