On-Ramp Integration

How do I change my API Keys?

Go to the Developers > API Keys page of your MoonPay dashboard and hit the roll button next to the API key you wish to replace. You will be given the option to immediately delete the old key or a 12hour rollover before the old API keys expire.

Iframe shows an error instead of the widget

If you see a CSP error that says buy.moonpay.com refused to connect, you’ll need to allowlist your production domain(s). We require this when you embed the MoonPay widget in an iframe or use the overlay, drawer, or embedded options to prevent unauthorized third-parties from embedding the MoonPay widget.

To resolve the issue, add your production domain(s) to the Settings page of your MoonPay dashboard.

Region-based widget error

If you see a widget error that geo-blocks certain users, confirm that these users are in a region supported by MoonPay. Non-supported countries, states, and territories for on-ramp

Sandbox Supported Currencies

Our sandbox environment supports a limited selection of testnet currencies; we recommend testing primarily with Ethereum on Sepolia or the Bitcoin testnet.

Multiple accounts in production

In our production environment, we only allow one account per user. Creating multiple accounts in production may cause your account to be flagged or blocked.

Test credit cards and KYC info in production

Only genuine card and KYC information may be used in our production environment. Do not use test credit card or test KYC information in production, as this will result in your account being blocked.

Using platforms like Flutter

MoonPay does not offer an SDK for Flutter. You'll have to manually embed our widget in a WebView. Consider the following tips:

  • You can create your own HTML that uses our Web SDK to embed our Widget. This will allow you to receive our Widget's events, if you wish. You'll then need to send them out to your Flutter app layer.
  • If you're experiencing camera issues in Flutter's WebView, consider using the Flutter plugin compatible with our Web SDK, available at https://pub.dev/packages/flutter_inappwebview.
  • You can find further guidance on configuring Flutter camera permissions and other related documentation at https://inappwebview.dev/docs/5.x.x/web-rtc/.
  • Custom Origin via baseUrl Property: For specific requirements, you can set a custom origin using the baseUrl property. This serves as the base URL for any relative paths in the HTML and sets the document’s origin.
    Example:
    InAppWebView(
      initialData: InAppWebViewInitialData(
        data: htmlContent,
        baseUrl: Uri.parse("https://your.custom.origin")
      ),
      // ... other configurations ...
    )
    
    This custom origin approach can be advantageous for scenarios involving scripts that validate the document’s origin or for CORS policies. We recommend using https://app_name, capacitor:// or equivalent as your custom origin for the baseUrl property. From here, add the domain to your allowlist in the settings page of your MoonPay dashboard.

App requirements for KYC flow

When not using the MoonPay SDK, you should ensure that the following requirements are met so that users can go through the KYC process.

Web view requirements

When using a web view, ensure the following:

  • The web view is able to access device local storage and initialize camera (for older iOS versions, the camera can be accessed only from Safari browser or WebView with SFSafariViewController)
  • HTML5 video playback is allowed (<video> tags are being used to send instructions): if video-instructions are not played, try using WebChromeClient to enable video playback
  • Autoplay in fullscreen mode is disabled and allowsInlineMediaPlayback is set as true for WebView

Selfie check requirements

  • Feature-Policy header for your webpage/frame or any other container has no restrictions for initializing camera like value camera 'none'.
  • Permissions-Policy header doesn't restrict access to a camera and microphone (for some cases) and if allow is set check for "camera; microphone" values.
  • Your website is being run on a secure https connection.

I'm having trouble adding my credit/debit card to my account?
