Plaid OAuth Support

Support Oauth Insitutions and more

Make sure that you have installed react-native-plaid-link-sdk

To support the Plaid OAuth flow on iOS you must be able to accept Universal Links. On Android, you must provide Android Package Name. See below for instructions.

Tasks

• iOS: Provide your sandbox and production redirect URIs to the Ratio team so that we can add them to your configuration

• Android: Provide your app's Android Package Name to the Ratio team so that we can add it to your configuration

Plaid OAuth Institutions

Wells Fargo
Bank of America
USAA
US Bank
Robinhood
Charles Schwab

iOS

Follow the instructions for adding Universal Links to your app and how to create and Apple App Site Association file that will be hosted at https://<your-domain>/.well-known/apple-app-site-association. This will allow the Plaid SDK to return back to your application after OAuth authentication has been complete.

Here is a sample apple-app-site-association file

{
   "applinks":{
      "details":[
         {
            "appIDs":[
               "<YOUR APP IDENTIFIER>"
            ],
            "components":[
               {
                  "/":"/plaid/*",
                  "comment":"Matches any URL whose path matches /plaid/*"
               }
            ]
         }
      ]
   }
}

You will also need to add Associated Domains Entitlement to your app and the associated domains feature to your app ID, which is documented here.

Example entitlements file for iOS which should be called <your-app>.entitlements

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>aps-environment</key>
	<string>development</string>
	<key>com.apple.developer.associated-domains</key>
	<array>
		<string>applinks:<YOUR-DOMAIN></string>
	</array>
</dict>
</plist>

Provide your redirect URI to the Ratio team so that we can add it to our configuration.

Android

Provide your Android Package Name to the RatioComponent

Provide your app's Android Package Name to the Ratio team so that we can add it to our configuration

Expo

If you are using Expo, you still need to go through the steps above, and also review Expo's documentation for handling Deep Linking.
