# Sell a NFT

The following sample will show you how to sell a NFT using the Hedera Hashgraph and Filecoin to store the media. We will first generate a request for the end user. Once validated, you will get notified for the NFT's selling success.

{% hint style="info" %}
In order to guarantee the process, the NFT will be transferred on an escrow account. User could withdraw anytime and get NFT back.
{% endhint %}

{% content-ref url="getting-started" %}
[getting-started](https://xact.gitbook.io/xact/sdk/javascript/getting-started)
{% endcontent-ref %}

## Step 1: Import the following modules <a href="#step-1-import-de-following-modules" id="step-1-import-de-following-modules"></a>

Let's continue building on the *index.js* from the previous example ([Environment Set-up](https://xact.gitbook.io/xact/sdk/getting-started#step-1-set-up-your-node-js-environment)) and add the following modules:

```javascript
const { Client, CategoryNFT } = require("@xact-wallet-sdk/client");
require("dotenv").config();
```

## Step 2: Initializing

When initializing a NFT's selling, a request will be sent to the end user

```typescript
/* Update the fields with your informations */
const fromAccountId = '' /* Account Id of the Seller */
const hbarAmount = 10 /* Unit Price per NFT in Hbar */
const nftIds = ['1@0.0.123456'] /* Array of nftIds to sell */
/* You can specify a quantity if you prefer to let us choose randomly for you */
/* But nftIds field cannot be set with quantity */
const tokenId = ''; /* token Id of the NFT */
const isCollection = ''; /* Sell the nftIds under one QR Code */
/* Optional NOT YET AVAILABLE - The NFT could only be sell to accountId present on that list */
const accountIds = ['', ''];
/* Optional - Add a middle men in order to collect fees */
const middleMen = {
    middleManAccountId,
    middleManTypeOfFees: MiddleManFeesType.HBAR,
    middleManFees: 10
};

/* If you're selling by nftIds replace quantity by ndtIds */
await client.sellNFT({fromAccountId, nftIds, hbarAmount, tokenId, accountIds, isCollection, middleMen});
```

## Step 3: Listen for the NFT's sell <a href="#step-3-listen-for-the-token-transfer" id="step-3-listen-for-the-token-transfer"></a>

Finally get notified when your NFT has been successfully set in sale !

```javascript
/* Subscribe to new sale NFT Validation */
client.sellNFTValidation().subscribe(nft => {
    console.log('NFT successfully set in sale', nft);
});
```

## Code Check ✅ <a href="#code-check" id="code-check"></a>

Your *index.js* file should look like this:

```javascript
const { Client, CategoryNFT } = require("@xact-wallet-sdk/client");
require("dotenv").config();

async function sellNFT() {

    //Grab your api key from your .env file
    const apiKey = process.env.API_KEY;


    // If we weren't able to grab it, we should throw a new error
    if (apiKey == null) {
        throw new Error("Environment variables API_KEY must be present");
    }
    /* Create a new instance of Client */
    const client = new Client({apiKey});
    
    /* Init the connexion */
    await client.initConnexion();
    
    /* Update the fields with your informations */
    const fromAccountId = '' /* Account Id of the Seller */
    const hbarAmount = 10 /* Unit Price per NFT in Hbar */
    const nftIds = ['1@0.0.123456'] /* Array of nftIds to sell */
    const tokenId = ''; /* token Id of the NFT */
    
    /* If you're selling by nftIds replace quantity by ndtIds */
    await client.sellNFT({fromAccountId, hbarAmount, tokenId, nftIds});
    
    /* Subscribe to new sale NFT Validation */
    client.sellNFTValidation().subscribe(nft => {
        console.log('NFT successfully set in sale', nft);
    });
}

sellNFT();
```
