Hey there,

I was able to import this collection into Postman (in a bit of a roundabout way) and tried to create a host, but it appears the payload sent in the body doesn't match what is sent when it's done via the GUI.

Body payload in the collection:

{
    "domain_names": [],
    "forward_scheme": "",
    "forward_host": "",
    "forward_port": "",
    "certificate_id": "",
    "ssl_forced": true,
    "hsts_enabled": true,
    "hsts_subdomains": true,
    "http2_support": true,
    "block_exploits": true,
    "caching_enabled": true,
    "allow_websocket_upgrade": true,
    "access_list_id": 0,
    "advanced_config": "",
    "enables": true,
    "meta": "",
    "locations": ""
}

Working payload taken from the request in the GUI (and reproduced in Postman); this was using a cert created from Cloudflare, rather than Let's Encrypt:

{
  "domain_names": [
    "subdomain.domain.com"
  ],
  "forward_scheme": "http/https",
  "forward_host": "",
  "forward_port": #,
  "access_list_id": "0",
  "certificate_id": #,
  "meta": {
    "letsencrypt_agree": false,
    "dns_challenge": false
  },
  "advanced_config": "",
  "locations": [],
  "block_exploits": false,
  "caching_enabled": false,
  "allow_websocket_upgrade": false,
  "http2_support": false,
  "hsts_enabled": false,
  "hsts_subdomains": false,
  "ssl_forced": false
}

Using the original payload returns a 400 "internal error" (which is not terribly useful in troubleshooting :) )

Doing some quick testing and trying to match the 1st to 2nd body, I think I discovered the error: "enables" should be "enabled". Even matching the body almost exactly would then return a "400 data should NOT have additional properties" error:

Changed the s to a and it worked!

Also need to mention that the domain_names field requires "" around the subdomain, otherwise the same Internal Server Error error is returned:

"domain_names": ["subdomain.domain.com"]
