(Header "app_id" has unallowed character "_") but required to be used

[DigitalInterface (Kolya)]

Hello, I’m currently trying to make a GET request, which requests a word from the Oxford Dictionary API, but to request something from it, you need an app_id and an app_key in the header of the request, but the console just throws an error which says that the underscores are not allowed.

Now I do not know what to do because of that error. Would there be any way to fix it?
Code:

local HttpService = game:GetService("HttpService")
local language = "en-us"
local word_id = "hello"
HttpService:RequestAsync({
	Url = "https://od-api.oxforddictionaries.com:443/api/v2/entries/"..language.."/"..word_id:lower(), 
	Method = "GET", 
	Headers = {
		["Content-Type"] = "application/json", ["app_id"] = "id", ["app_key"] = "key" -- i removed key and id
	}
})

You should send a message to @Bug-Support with details, because they should be allowed.

Apparently roblox needs to change a config on their side.

In the meantime, it is a bug, and you’ll need a workaround. Possible ones:

• Maybe the oxford API has some undocumented things you can try:

  • Try using app-id and app-key, maybe the oxford API will accept hyphens
  • Maybe they’ll accept a standard Authentication header instead of separate id/keys. This is just a base64-encoded "id:key" string. I wrote code for doing this in roblox here. Try that instead of these two headers?

• Host your own server that uses better-named headers and forwards them to oxford’s API. More complex but there are lots of online hosting options that would let you do this relatively cheaply.

The hyphens did work, thank you!
