Users will link their bank account to Ratio using Plaid. You do not need to set up an account with Plaid.
If you are building an iOS app you need to provide and production redirect URIs, so that we can configure Plaid to properly redirect users to your application. If you are building an Android app, you need to provide us with the Android Package Name. These values need to match what you send in yourrequestLink calls
The first step in connecting a user's bank account is to request a from our API, then pass that Link Token into Plaid's SDK.
You now have a link token that looks something like this: link-sandbox-ab12c3d4-0000-123a-987f-26e621c2ee51. This token needs to be provided to Plaid through one of several methods:
Below you will find links to the Plaid SDKs used to launch the Plaid bank account authentication flow.
To install, run: npm install --save react-native-plaid-link-sdk
Make sure you share your Android package name with Ratio (ex com.plaid.example)
To install with Cocoapods, run: pod 'Plaid', see the documentation for other options.
To install, run: npm install --save react-plaid-link
Now that you have a public token, you can proceed with the next step, which is to open Plaid Link SDK using the public token you requested from Ratio above.
Once you open the Plaid Link SDK, monitor for onSuccess and onExit events.
If onSuccess - the user has successfully linked their bank account and you proceed with adding the bank account to the user account
If onExit - the user did not successfully authenticate their account (closed the Plaid SDK, bank connect was down, etc.) and you should bring them back to the screen that you are launching Plaid from

Bank account connections can be disconnected from time to time, possibly at the request of the user or the financial institution. If a user wishes to perform a transaction, but the bank link has been disconnected, you will receive a . To repair this, request an update token and go through the Plaid flow again.
