You can send notification messages administrators via Advanced API. All you have to do is to enter specific administrator
identifier into the `admin` parameter. You can find this identifier in the admin manager.

![Admin ID](docs:advanced-transactional-admin/admin_id)

## Example of the request:
```http-json
POST /api/2.0/advanced/transactional HTTP/1.1
Host: portal.bulkgate.com
Content-Type: application/json

{
	"application_id": 451,
	"application_token": "NKN02TWE6NfBkfl-your-secret-token-Wf05GaqLIWLW4aBj",  	
	"admin": 154,
	"text": "Hi <first_name>, it is nice to meet you. <email>"
}
```

It is possible to add variables in the text that will be replaced by specific admin values before sending the message.

**The final message then looks like this:**
```text
Hi Thomas, it is nice to meet you. thomas@example.com
```

**Here is the complete list of variables:**

| VARIABLE | MEANING |
|:--- |:---|
| `<first_name>` | First name |
| `<last_name>` | Last name | 
| `<phone_number>` | Phone number|
| `<email>` | Email address |
