De-provisioning an existing certificate requires you to make a POST request to the tls endpoint
Sample Request
Replace the API_KEY with your BrandSSL token. You can get your authorization token from the settings page of your dashboard,
curl -XPOST -H "Content-type: application/json" -d '{
"domain": "www.example.com"
}' 'https://www.brandssl.io/api/{API_KEY}/disable'
If the request is successful, you will get an HTTP status 200 response.
