<ParamField header="Authorization" type="string" required initialValue="Api-Key <LAUDSPEAKER_API_KEY>" placeholder="Api-Key <LAUDSPEAKER_API_KEY>">
  Header for authenticating with Laudspeaker. Starts with `Api-Key` followed by the API key, for example `Api-Key M4jxXt6diYz1Dds1YmhHe93KGPAUi24PlXgaiRXi`.
</ParamField>

<ParamField body="batch" type="Event[]" required placeholder="click">
  This field contains the array of events.
</ParamField>

An event looks like:

```
{
      "timestamp": "2024-03-15T02:31:05.295Z",
      "uuid": "F451DF0A-D713-4076-AE20-41AB1641BC98",
      "event": "purchase",
      "source": "mobile",
      "correlationKey": "_id",
      "payload": {
        "cart": true
      },
      "correlationValue": "FBBBCB26-B75E-4342-B40B-568BF879F7C5"
    },
```

An event must contain an **event** field (string), **correlationKey** field (string), **correlationValue** field (string), and a **source** set to **"custom"** and can optionally contain a **payload** object which contains data you want to send
