# How to Build a Token Approval & Revoke Dashboard (Revoke.cash-Style)

> Learn how to build a dashboard to view and revoke token approvals using the Moralis API.

## Introduction

In this tutorial, you'll learn how to build a token approval dashboard similar to Revoke.cash using the Moralis API. Users can view all their ERC20 token approvals and identify potentially risky unlimited approvals. This is an important security tool for managing DeFi permissions. We'll use the following Moralis API endpoint:

* [Get Token Approvals](/data-api/evm/wallet/approvals) - Fetch all token approvals granted by a wallet

## Prerequisites

* Node.js v18+ installed
* A Moralis API key ([get one free](https://admin.moralis.io))

## Step 1: Set Up Your Project

Create a new directory for your project and initialize it:

```bash theme={null}
mkdir revoke-dashboard && cd revoke-dashboard
npm init -y
```

## Step 2: Create the Script

Create a file called `index.js` and add the following code:

```javascript theme={null}
// index.js
const API_KEY = 'YOUR_API_KEY';
const WALLET_ADDRESS = '0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045';

async function getTokenApprovals() {
  const response = await fetch(
    `https://deep-index.moralis.io/api/v2.2/wallets/${WALLET_ADDRESS}/approvals?chain=eth`,
    {
      headers: {
        'X-API-Key': API_KEY,
      },
    }
  );

  const data = await response.json();
  console.log(JSON.stringify(data, null, 2));
}

getTokenApprovals();
```

Replace `YOUR_API_KEY` with your actual Moralis API key.

## Step 3: Run the Script

```bash theme={null}
node index.js
```
