# Wait for a status change on a given pump

**GET /gas-stations/{gasStationId}/pumps/{pumpId}/wait-for-status-change**

Uses **long polling** to wait for a status change on a given pump. Returns as soon as the status has changed or after the number of seconds provided by the optional `timeout` query parameter (default timeout is 30 seconds). In case of timeout (408 status code) you're safe to start the request again. Instantaneously returns if `lastStatus` was given and already changed between request. If successful, it returns the same structure as the normal status call

Only use after approaching, otherwise returns `403 Forbidden`.

### 401: OAuth token missing or invalid or a linked identity is missing.

Linked identity missing is a special case where you need to make sure that
the user has additionally logged in / authorized with a third-party.

This is not relevant for most use-cases.

The specific error code that identifies a missing linked identity is `missing-linked-identity`

Example:

```
  {
      "errors": [
          {
              "id": "cbgmhslmp1o9or9kh1p0",
              "title": "Missing linked identity for authorized access",
              "detail": "Linked identity is needed to access this resource, please check why the user does not have a linked identity",
              "status": "401",
              "code": "missing-linked-identity"
          }
      ]
