# Plaid Integration

If you have implemented your own [Plaid Integration](/v5.0/integrations/banking/plaid/integrating-plaid), then you will also want to take advantage of the Tight Embedded experience's `registerPlaidLinkListener` functionality. By registering a listener, the Tight Embedded experience's existing Plaid-related CTAs will invoke the callback function you provide, so that you can route the user to your own Plaid Link-related UI.

To register the listener, simply add the following line of JS to be ran once after `Hurdlr.init({...})`:

```javascript theme={null}
Hurdlr.registerPlaidLinkListener(myPlaidLinkCallback);
```

Whenever a user presses a Plaid Link CTA in Tight's Embedded experience, `myPlaidLinkCallback` will be invoked, with a JSON object as the single argument, containing the following attributes:

| Field            | Description                                                                                                                                                                                                                                                                                                                                                                                                                                                    | Format                                                                                                                                                |

An example of the arguments passed to `myPlaidLinkCallback` for an item requiring a [Plaid Link Update](https://plaid.com/docs/link/update-mode/) is shown below:

```json theme={null}
{
  type: "PLAID_LINK_RESET", // compare to Hurdlr.PLAID_LINK_RESET
  errorCode: "ITEM_LOGIN_REQUIRED",
  plaidAccessToken: "YOUR_USERS_PLAID_ACCESS_TOKEN",
  screen: "expenseDash"
}
```
