#### Fetching all Flow Schedules for a certain sender

```javascript
{
  flowScheduleCreatedEvents(where: {sender: "0xbd5a76f59df49527e47df66d7d7b5590a237871d"}) {
    id
    order
    sender
    receiver
    startAmount
    startDate
    startDateMaxDelay
    superToken
    flowRate
  }
}
```

{% hint style="info" %}
Note that that the `id` attribute is formatted as "{Event Name}-{Transaction Hash}-{Log Index}". Log index is provided as it's possible that multiple of the same event occur in the same transaction, so with the log index gives unique identification.<br>

`id:` `"FlowScheduleCreated-0x04ca752e609289f6144df3e0096ccb9772ba4923781612096ec5582f62c3ff46-171"`

#### Fetching all Flow Deletion tasks executed before a certain time

    superToken
  }
