Crypto Withdrawals

Web Application

Example using React:

import React from 'react';
import ZeroHashSDK, { AppIdentifier } from 'zh-web-sdk';

const App = () => {
  const sdk = new ZeroHashSDK({
    zeroHashAppsURL: "https://web-sdk.cert.zerohash.com",
    cryptoWithdrawalsJWT: "<JWT_TOKEN_HERE>" 
  });

  sdk.openModal({appIdentifier: AppIdentifier.CRYPTO_WITHDRAWALS})
  return <></>;
}

export default App;

Mobile Application (WebView)

To use our SDK on mobile apps, you don't need to install or include zh-web-sdk as a dependency in your project. We use a proxy server that calls the SDK internally to make it work for mobile applications.

Events

We forward events from the UI to the native app using the postMessage API. You can handle these events from the WebView component. Currently, these are the events we have:

Message	Meaning
SDK_MOBILE_READY	The SDK is ready to receive postMessage events (e.g OPEN_MODAL)
CRYPTO_WITHDRAWALS_APP_LOADED	The SDK is loadedSDK loaded and is visible to the customer.
CRYPTO_WITHDRAWALS_CLOSE_BUTTON_CLICKED	The close (X) button was clicked in the top right corner of the UI.
CRYPTO_WITHDRAWALS_COMPLETED	The flow was completed and internal calls were made successfully. Note: “completed” does not equate to “approved” or “success”. The flow can be successfully completed, but the participant status could be “rejected”, for example.
CRYPTO_WITHDRAWALS_FAILED	The customer encountered an error that cannot be rectified in their current session.

Messages

To control the WebView, you can also send messages using the postMessage API after receiving SDK_MOBILE_READY from WebView. Currently, the accepted messages are:

Open Modal

Opens the modal with the JWT provided for identifier provided.

{type: "OPEN_MODAL", payload: {jwt: "<JWT_HERE>", appIdentifier: "crypto-withdrawals"}}

Close Modal

Closes the modal for identifier provided.

{type: "CLOSE_MODAL", payload:{appIdentifier: "crypto-withdrawals"}}
