Integrate Off-Ramp using our SDKs
Build a working MoonPay crypto-to-fiat off-ramp integration with your test API key.
- Sign in to your MoonPay dashboardand navigate to the Developers section to access your test API keys.
- Personalize your widget using the options available on our off-ramp parameters page.
- Don't forget to include the domain where the off-ramp will be displayed in your allowed domains list.
Our Web SDK is available for desktop use, while mobile users can opt for our React Native, iOS, or Android SDKs.
To integrate our Web SDK, simply add it as a script in your HTML file. After incorporating this script, your application will be set to initiate our JavaScript Web SDK, complete with customizable options for flow, environment, variant, as well as Buy, Sell, or Swap-related parameters.
<!--Adds the MoonPay SDK as a script to your HTML file-->
<script defer src="https://static.moonpay.com/web-sdk/v1/moonpay-web-sdk.min.js"></script>
<!--Initialize the SDK in your application with the flow, environment, variant, and any parameters related to Buy, Sell or Swap.-->
<script>
window.onload = function() {
const moonpaySdk = window.MoonPayWebSdk.init({
flow: 'sell',
environment: 'sandbox',
variant: 'overlay',
params: {
apiKey: 'pk_test_key',
theme: 'dark',
quoteCurrencyCode: 'usd',
baseCurrencyAmount: '.01',
defaultBaseCurrencyCode: 'eth'
},
debug: true
});
}
</script>
Launch the MoonPay widget in Overlay, New Tab, New Window modes, or as an Embedded iFrame.
Legacy integration
To benefit from our latest features we strongly advise using our SDKs. However, if your technology stack is incompatible, you can opt for our legacy browser based widget URL integration.
You can use the below pre-written code to quickly get started on adding a 'Sell Crypto' button that opens the MoonPay widget in a new browser tab.
<!--Opens the MoonPay widget in a new browser tab-->
<body>
<div class="container">
<button onclick="window.open('https://sell-sandbox.moonpay.com/?apiKey=pk_test_123', '_blank')">Sell with MoonPay</button>
</div>
</body>
.container {
background-color: #392a54;
padding: 20px;
text-align: center;
}
button {
background-color: #7d00fe;
border: none;
color: white;
padding: 15px 50px;
font-size: 16px;
cursor: pointer;
border-radius: 4px;
background-image: url('https://images.crunchbase.com/image/upload/c_lpad,h_170,w_170,f_auto,b_white,q_auto:eco,dpr_1/jglje7ar0xc6j5lvai6t');
background-repeat: no-repeat;
background-position: right center;
background-size: contain;
}
Here's an example. Give it a try!
