## Authentication

All endpoints use the standard PADS4 session cookie. Obtain it once and reuse:

```bash theme={null}
# Log in and save the session cookie
curl -c cookies.txt -X POST 'https://<your-server>/api/v1/Account/Logon' \
  -H 'Content-Type: application/json' \
  -d '{"UserName": "admin", "Password": "yourpassword", "Domain": "yourdomain"}'

# Use the cookie on all subsequent requests
curl -b cookies.txt -X GET 'https://<your-server>/rdx/<ServiceName>/...'
```

> Replace `https://<your-server>` with your PADS4 server address and `<ServiceName>` with the service path shown above.
