# Creating a user consent application using the Node SDK

## Set up your Node.js application

### Creating the project

Now, we'll create a Node.js project using npm. This creates a `package.json` file and the core dependencies necessary to start coding.

To create the project:

1. Navigate to the folder in which you'd like to store your project.
2. Create a folder called `sinch-user-consent`.
3. Create the following directory structure:

```shell
  sinch-user-consent
    index.js
```
4. Run the command:



```shell
npm init
```

This command adds the `node_modules` folder and the `package.json` file. You will be prompted to provide values for the fields. For this tutorial, you can simply accept the default values and press enter at each stage.

### Installing the SDK

You can install the Sinch Node.js SDK using either [NPM](https://www.npmjs.com/) or [Yarn](https://yarnpkg.com/):

NPM

```shell
npm install @sinch/sdk-core
```

Yarn

```shell
yarn add @sinch/sdk-core
```

### Fastify

Fastify is a lightweight webserver that we will use to respond to webhooks. Install Fastify with the command:


```shell
npm install fastify
```

### Installing ngrok

If you successfully completed the *Receive an SMS Message* guide, you'll have used ngrok to set up a tunnel to your local server. Install ngrok with the command:


```shell
npm install ngrok -g
```

If you haven't already, set up a free account with ngrok. Now we've installed everything we need, we can start creating the application.

### Collecting information to initialize the client

On the next page, you'll need to intialize the SDK.

Before initializing a client using this SDK, you'll need three pieces of information:

- Your Project ID
- An access key ID
- An access key Secret


These values can be found on the [<b>Access Keys</b>](https://dashboard.sinch.com/settings/access-keys) page of the Sinch Build Dashboard. You can also [create new access key IDs and Secrets](https://community.sinch.com/t5/Conversation-API/How-to-get-your-access-key-for-Conversation-API/ta-p/8120), if required.
