Plaid React Native SDK

The Plaid React Native SDK provides the client-side component that your users will interact with in order to link their accounts to Plaid and allow you access to their accounts via the Plaid API.

For more information about Plaid Link check out our introduction documentation.

Plaid currently supports two versions of the Plaid React Native SDK v10.x and v11.x. You can find v10 on the master-v10 branch.

Features

The SDK provides:

• A PlaidLink functional component.
• A function to open Link.
• A hook to handle onEvent callbacks.
• A function to dismiss link on iOS.

Getting Started

Get started with our 📝 documentation and the 📱example project, or ↔️ Tiny Quickstart (React Native) which is an end to end example demonstrating a minimal integration with this SDK.

If you're unfamiliar with React Native we recommend starting with the environment setup instructions.

In your React Native project directory:

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

iOS Setup

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

pod 'Plaid', '~> <insert latest version>'

Autolinking should install the CocoaPods dependencies for iOS project. If it fails you can run

cd ios && bundle install && bundle exec pod install

Android Setup

• Android 5.0 (API level 21) and above.
  • Your compileSdkVersion must be 33.
• Android gradle plugin 4.x and above.

AutoLinking should handle all of the Android setup.

Remember to register your Android package name in the Dashboard. This is required in order to connect to OAuth institutions (which includes most major banks).

React Native Setup

• To initialize PlaidLink, you will need to first create a link_token at /link/token/create. Check out our QuickStart guide for additional API information.

Version >= 11.6.0

Starting from version 11.6.0, we introduced the ability to preload part of the Link experience. You can initiate the preloading process by invoking the create function.

function createLinkTokenConfiguration(
  token: string,
  noLoadingState: boolean = false,
): LinkTokenConfiguration {
  return {
    token: token,
    // Hides native activity indicator if true.
    noLoadingState: noLoadingState,
  };
}

const tokenConfiguration = createLinkTokenConfiguration("#GENERATED_LINK_TOKEN#");
create(tokenConfiguration);

After calling create, you can subsequently invoke the open function. Note that maximizing the delay between these two calls will reduce latency for your users by allowing Link more time to load.

function createLinkOpenProps(): LinkOpenProps {
  return {
    onSuccess: (success: LinkSuccess) => {
      // User was able to successfully link their account.
      console.log('Success: ', success);
    },
    onExit: (linkExit: LinkExit) => {
      // User exited Link session. There may or may not be an error depending on what occured.
      console.log('Exit: ', linkExit);
      dismissLink();
    },
    // MODAL or FULL_SCREEEN presentation on iOS. Defaults to MODAL.
    iOSPresentationStyle: LinkIOSPresentationStyle.MODAL,
    logLevel: LinkLogLevel.ERROR,
  };
}

const openProps = createLinkOpenProps();
open(openProps);

Version < 11.6.0

In versions prior to 11.6.0, you can open a link by calling the openLink function.

// Create PlaidLinkProps from the provided token string.
function makeLinkTokenProps(token: string): PlaidLinkProps {
  return {
    tokenConfig: {
      token: token,
      logLevel: LinkLogLevel.ERROR,
      // Hides native activity indicator if true.
      noLoadingState: false, 
    },
    onSuccess: (success: LinkSuccess) => {
      // User was able to successfully link their account.
      console.log('Success: ', success); 
      success.metadata.accounts.forEach(it => console.log('accounts', it));
    },
    onExit: (linkExit: LinkExit) => {
      // User exited Link session. There may or may not be an error depending on what occured.
      console.log('Exit: ', linkExit);
      dismissLink();
    },
    // MODAL or FULL_SCREEEN presentation on iOS. Defaults to MODAL.
    iOSPresentationStyle: LinkIOSPresentationStyle.MODAL,
  };
}

const linkTokenProps = makeLinkTokenProps("#GENERATED_LINK_TOKEN#");
openLink(linkTokenProps);

OAuth requirements

:warning: All integrations must migrate to version 9.0.0 or later of the React Native SDK (requires version 4.1.0 or later of the iOS LinkKit SDK) by January 1, 2024, to maintain support for Chase OAuth on iOS.

Android OAuth Requirements

Register your app package name

1. Log into your Plaid Dashboard and navigate to the API page under the Developers tab.
2. Next to Allowed Android package names click "Configure" then "Add New Android Package Name".
3. Enter your package name, for example com.plaid.example.
4. Click "Save Changes", you may be prompted to re-enter your password.

iOS OAuth Requirements

For iOS OAuth to work, specific requirements must be met.

1. Redirect URIs must be registered, and set up as universal links.
2. Your native iOS application, must be configured with your associated domain. See your iOS set up universal links for more information.

Link Token OAuth Requirements

• On iOS you must configure your link_token with a redirect_uri to support OAuth. When creating a link_token for initializing Link on Android, android_package_name must be specified and redirect_uri must be left blank.

• On Android you must configure your link_token with an android_package_name to support OAuth. When creating a link_token for initializing Link on iOS, android_package_name must be left blank and redirect_uri should be used instead.

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, use the usePlaidEmitter hook in react functional components:

  usePlaidEmitter((event: LinkEvent) => {
    console.log(event)
  })

Upgrading

Plaid releases updates to the SDK approximately every few months. For the best user experience, we recommend using the latest version of the SDK.

Major SDK versions are released annually. SDK versions are supported for two years; with each major SDK release, Plaid will stop officially supporting any previous SDK versions that are more than two years old.

While these older versions are expected to continue to work without disruption, Plaid will not provide assistance with unsupported SDK versions.
