# Create Plaid Link Token

POST https://live.tradovateapi.com/v1/achApplication/createplaidlinktoken
Content-Type: application/json

### Create a Plaid Link token for a new or existing ACH connection.**Available to:** All authenticated users**Environments:** Live**[Rate Limit](/connect/overview/core-concepts/rate-limits):** No endpoint-specific limitCreate the token your client uses to initialize Plaid Link. The service associates the token with the authenticated user, so you don't need to provide `userId`.Omit `achApplicationId` to start a new connection. To repair a connection whose ACH application has the `RequiresRelink` status, provide that application's ID. The application must belong to the authenticated user. In relink mode, the token updates the existing Plaid item instead of requesting a new connection.The platform-specific fields are optional:- Set `redirectUri` for a browser or iOS OAuth return flow. Register the value in NinjaTrader's Plaid configuration before using it.
- Set `androidPackageName` for an Android app-link flow, and omit `redirectUri`. Register the package name in NinjaTrader's Plaid configuration before using it.
- Omit both fields when the client flow doesn't use them.The platform fields are mutually exclusive; never send both. NinjaTrader forwards each supplied value to Plaid without first checking whether Plaid accepts or has registered it, so an unregistered or unsupported value produces Plaid's generic token-request error. Pass the response's `token` to the client-side Plaid Link SDK.**Warning:** Business failures return `HTTP 200` with `errorText` and no `token`. Check `errorText` before initializing Plaid Link.**Common Failure Scenarios**- The relink application doesn't exist or doesn't belong to the authenticated user.
- Plaid rejects the token request or is temporarily unavailable.
- The request is sent to the Demo environment.**Error Messages**| Message                                     | Response             | Trigger                                                                            |
