# sign-in-not-needed

> This link session doesn't sign in, or already did.

| Status | Title |
| - | - |
| `409` | No sign-in needed |

## Where you see it

Only inside the hosted flow, which handles it. You don't need to handle it in your app or on your server.

## What it means

Only a link session for one of your users (`external_user_id`) signs in, and only once: your user signs in to their own Plugchoice account when your integration adds chargers to that account. Other link sessions don't sign in.

## What to do

Nothing.

## Example

```json theme={null}
{
  "type": "https://developer.plugchoice.com/sdk/errors/sign-in-not-needed",
  "title": "No sign-in needed",
  "status": 409,
  "code": "sign-in-not-needed",
  "detail": "Only an integration's users sign in, once, when the chargers go to their own account."
}
```
