React Native Plaid Link V11 Migration Guide

Overview

The upgrade from Plaid Link 9.x/10.x to 11.x introduces several important changes. It's crucial to understand these modifications to ensure your integration remains robust and error-free.

Changes from SDK 9.x/10.x to 11.0

React Native Changes

  1. BREAKING - Authentication Method Changes: Public key authentication support has been removed. It's imperative to migrate to Link Tokens. If your integration uses the public key, use the migration guide for detailed instructions on transitioning to Link tokens.

  2. BREAKING OAuth Redirect Handling: The deprecated useDeepLinkRedirector method for OAuth redirects has been removed. If your code relies on this method, it can be safely removed as it's no longer required.

  3. React Native Version Compatibility: You can now use Plaid Link with any version of React Native. However, we recommend using a version that is not archived for optimal performance and compatibility.

iOS Changes

  1. BREAKING - iOS Version Support: Plaid Link no longer supports iOS 11, 12, and 13. If your application still targets these iOS versions, you must either continue using SDK 9.x/10.x or update your app to support newer iOS versions compatible with iOS SDK V5.x.

  2. BREAKING - iOS Event Metadata Encoding: Event metadata keys are now encoded in snake_case instead of camelCase to match Android behavior. For example, errorType is now encoded as error_type. Update your code to handle these changes correctly. Refer to ios/RNLinksdk.m for the full set of iOS keys.

Android Changes

  1. Upgrade to Kotlin 1.8 The Link Android SDK now uses Kotlin 1.8. Ensure your project is updated to this version to maintain compatibility.
