Plaid Link for React Native

Getting Started

In your react-native project directory:

npm install --save react-native-plaid-link-sdk

Updating from previous versions.

When upgrading from a previous major version of this library, see the notes here for additional instructions.

iOS

Add Plaid to your project’s Podfile as follows (likely located at ios/Podfile). The current minimum version supported is 1.1.27.

pod 'Plaid', '~> 1.1.27'

Then install your cocoapods dependencies:

cd ios && pod install && cd ..

Add a Run Script build phase (after the [CP] Embed Pods Frameworks step) to your target as described in Plaid Link for iOS documentation. This strips simulator symbols from App Store release builds.

That's it if using a recent react-native version with autolinking support.

Manual Integration

If using a version of react-native without autolinking support, then you will need to:

`react-native link react-native-plaid-link-sdk`

followed by

1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
2. Go to node_modules ➜ react-native-plaid-link-sdk ➜ ios and add RNLinksdk.xcodeproj
3. In XCode, in the project navigator, select your project. Add libRNLinksdk.a to your project's Build Phases ➜ Link Binary With Libraries
4. Run your project (Cmd+R)<

Android

To register your app id:

1. Log into your Plaid Dashboard at the API page
2. Next to Allowed Android package names click "Configure" then "Add New Android Package Name" (for example com.plaid.example)
3. Click "Save Changes", you may be prompted to re-enter your password

android/app/src/main/java/<AppName>/MainApplication.java

Add import com.plaid.PlaidPackage; on the imports section

Add packages.add(new PlaidPackage()); in List<ReactPackage> getPackages();

android/app/build.gradle

Add implementation project(':react-native-plaid-link-sdk') and implementation 'com.plaid.link:sdk-core:1.0.0' in the dependencies block

android/settings.gradle

Add:

include ':react-native-plaid-link-sdk'
project(':react-native-plaid-link-sdk').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-plaid-link-sdk/android')

PlaidLink

In your app:

import Text from 'react-native';
import PlaidLink from 'react-native-plaid-link-sdk';
 
const MyPlaidComponent = () => {
  return (
    <PlaidLink
     // Replace any of the following <#VARIABLE#>s according to your setup,
     // for details see https://plaid.com/docs/quickstart/#client-side-link-configuration
 
      publicKey='<# Your Public Key #>'
      clientName='<# Your Client Name #>'
      env='<# Environment #>'  // 'sandbox' or 'development' or 'production'
      product={['<# Product #>']}
      onSuccess={data => console.log('success: ', data)}
      onExit={data => console.log('exit: ', data)}
      onCancelled = {(result) => {console.log('Cancelled: ', result)}}
 
      // Optional props
      countryCodes={['<# Country Code #>']}
      language='<# Language #>'
      userEmailAddress='<# User Email #>'
      userLegalName='<# User Legal Name #>'
      userPhoneNumber='<# User Phone Number #>'
      webhook='<# Webhook URL #>'
    >
      <Text>Add Account</Text>
    </PlaidLink>
  );
};

To receive onEvent callbacks:

The React Native Plaid module emits onEvent events throughout the account linking process — see details here. To receive these events in your React Native app, wrap the PlaidLink react component with the following in order to listen for those events:

import React from 'react';
import { Text, NativeEventEmitter, NativeModules } from 'react-native';
 
class PlaidEventContainer extends React.Component {
 
  componentDidMount() {
    const emitter = new NativeEventEmitter(Platform.OS === 'ios' ? NativeModules.RNLinksdk : NativeModules.PlaidAndroid);
    this._listener = emitter.addListener('onEvent', (e) => console.log(e));
  }
 
  componentWillUnmount() {
    if (this._listener) {
      this._listener.remove();
    }
  }
 
  render() {
    return (
      <PlaidLink
        clientName='##YOUR CLIENT NAME##'
        publicKey='#YOUR PUBLIC KEY##'
        env='sandbox'
        onSuccess={data => console.log('success: ', data)}
        onExit={data => console.log('exit: ', data)}
        onCancelled = {(result) => {console.log('Cancelled: ', result)}}
        product={['transactions']}
        language='en'
        countryCodes={['US']}
      >
        <Text>Add Account</Text>
      </PlaidLink>
    );
  }
}

Customizing the PlaidLink component

By default, PlaidLink renders a TouchableOpacity component. You may override the component used by passing component and componentProps. For example:

      <PlaidLink
        clientName = "Component Test"
        publicKey = "##YOUR PUBLIC KEY##"
        products = {["transactions"]}
        env = "sandbox"
        component= {Button}
        componentProps = {{title: 'Add Account'}}
        onSuccess = {(result) => {console.log('Success: ', result)}}
        onError = {(result) => {console.log('Error: ', result)}}
        onCancelled = {(result) => {console.log('Cancelled: ', result)}}
        product = {["transactions"]}
        language = "en"
        countryCodes = {["US"]}
