How do I send authentication details with a HTTP GET request using RequestAsync?

Hello,

This is a fairly simple issue that I’m dealing with, in that I don’t know how to include authentication details (just a simple username and password) with a HTTP GET request with RequestAsync(). Do I write the info as a header? If so, how exactly do I do this, and do I need to format it in a certain way?

I’ve tried some things and they haven’t worked, and searching has pulled up no straightforward answers.

I’d appreciate any help with this.

local cred = (username..":"..password)

local request = httpService:RequestAsync({
    Url="https://www.example.com",
    Headers = {['Authorization']=("Basic "..cred}, -- this is supposed to provide the username and password for authentication
    Method="GET"    
})
