# Custom Headers

We also support custom headers to fulfill your additional requirements when making the API requests.

Let's take a look at illustration below, making the completed project event as the example. The webhook now will also provide the additional request headers of `key1` and `key2` items.

## Project Created

A `PROJECT_CREATED` event will be sent when a new project is created.

### Example

#### Request Header

```json
{
  "accept-encoding": "gzip, compress, deflate, br",
  "accept": "application/json, text/plain, */*",
  "content-length": "200",
  "content-type": "application/json",
  "key1": "value1",
  "key2": "value2",
  "user-agent": "Datasaur",
  "x-datasaur-signature": "643a34cd1a649b37a6d3611ff7fb561a0255e899ca89a9475c79b38764775033"
}
```

#### Request Body

```json
{
  "eventType": "PROJECT_CREATED",
  "data": {
    "timestamp": "2023-11-17T09:02:45.258Z",
    "project": {
      "id": "N2E4MjNlYTc",
      "name": "hamlet.TXT",
      "tags": [
        "CUSTOM"
      ]
    },
    "team": {
      "id": "1",
      "name": "User's Team Workspace"
    }
  }
}
```
