Install

💡 This package requires react-native-webview to be installed in your project. Although it is listed as direct dependency, some times it is not installed automatically (This is a known npm issue). You should install it manually via following command in this case:

npm install --save [email protected]

# or with yarn
yarn add [email protected]

Connect through linkToken

The connection link token should be obtained from the Get link token endpoint. Request must be performed from the server side because it requires the client secret. You will get the response in the following format: You should use content --> linkToken from this response to run the FrontFinance component.

here is an example http request using request API in JS:

const options = {
  method: 'POST',
  headers: {
    accept: 'application/json',
    'content-type': 'application/*+json',
    'X-Client-Secret': 'XXXX', // replace with your client secret
    'X-Client-Id': 'XXXX' // replace with your client id
  },
  body: '{"userId":"XXXX"}' // replace with your user id (could be user email or phone number)
};

const getLinkToken = async () => {
  const response = await fetch('https://integration-api.getfront.com/api/v1/linktoken', options);
  const json = await response.json();
  return json?.content?.linkToken;
};

You will get a response in the following structure:

{
  "content": {
    "linkToken": "REQUESTED_LINK_TOKEN"
  },
  "status": "ok",
  "message": "",
  "errorType": ""
}

Using the FrontFinance component

import React from 'react';
import {
  FrontFinance,
  FrontPayload,
  TransferFinishedPayload,
  TransferFinishedSuccessPayload,
  TransferFinishedErrorPayload
} from '@front-finance/frontfinance-rn-sdk';

export const App = () => {
  return (
    <FrontFinance
      linkToken={"YOUR_LINKTOKEN"}
      onBrokerConnected={(payload: FrontPayload) => {
        // use broker account data
      }}
      onTransferFinished={(payload: TransferFinishedPayload) => {
        if (payload.status === 'success') {
          const successPayload = payload as TransferFinishedSuccessPayload
          // use transfer finished data
        } else {
          const errorPayload = payload as TransferFinishedErrorPayload
          // handle transfer error
        }
      }}
      onClose={() => {
        // use close event
      }}
      onError={(err: string) => {
        // use error message
      }}
    />
  )
}

export default App;
