Discord Add Guild Member 401 Error Despite Apparently Valid Access Token

I am answering my own question as I may have figured this out. It works when I execute the below:

using (WebClient client = new WebClient())
    client.Headers.Add(HttpRequestHeader.ContentType, "application/json");
    client.Headers.Add(HttpRequestHeader.Authorization, "Bot [Redacted]");
    string output = client.UploadString

Notice that I changed from a content type of "application/x-www-form-urlencoded" to "application/json." I changed from using an Authorization header of "Bearer" to "Bot," and I am using my bot's token. I am using the same access token as before. I plan to accept this answer if no better solutions come in.

    I am new to Discord's API, and I am working a project which needs to be able to add a guild member programmatically. I've learned how to get an authorization code (with identify and guilds.join scopes), redeem it for an access token, and get a user's ID. The last step is to use the access code and user ID to add the guild.

    I am certain that my access token is valid and the request should be too. I have a bot with bot guilds.join scope which is from an

    I am getting a 401 unauthorized when i use GET on /guilds/{guild.id}/channels, Does this have something to do with the gateway?

    Use Case: DiscordServers.com uses the Add Guild Member endpoint to add users to the server they want to join. Server owners would really appreciate the ability to specify what channel people see when they join the server, without updating the order of channels.

    in my project i use laravel with ouath from socialite discord composer package, by default socialite only use identity and email, and you must add guild.joins scope manually, you can add guild.joins in vendor->scocialiteproviders->discord->provider.php.

    Because Add Guild Member itself has an entirely different use case. It allows you to very finely control who you let into a Discord server and when, because with the added OAuth2 step involved you can inspect the discord users account before adding them, possibly cross-referencing them with a 3rd party site (i.e. forum membership or subscriptions)
