Fixing 401 Unauthorized Error with Socialite Discord

@RobertsP Thank you for helping me, but could you assist me with this? I want to automatically add users to a group if they are not already in the group. I tried this but got a 401 error

array:2 [▼
  "status_code" => 401
  "response_body" => array:2 [▼
    "message" => "401: Unauthorized"
    "code" => 0
  ]
]

You need to provide your bot token in authorization header like this Bot {$botToken} and also you need to provide user's access_token in your request body.

This information is written in discord's official docs: https://discord.com/developers/docs/resources/guild#add-guild-member

Here is how I implemented it in my laravel application.

    protected function joinGuild(string $accessToken, string $userId): bool
    {
        $guildId = config('services.discord.guild_id');
        $botToken = config('services.discord.bot_token');

        $response = Http::withHeaders([
            'Authorization' => "Bot {$botToken}"
        ])->asJson()
          ->put("https://discord.com/api/v10/guilds/{$guildId}/members/{$userId}", [
              'access_token' => $accessToken,
              'roles' => ['1248232571763163156']
          ]);

        if ($response->successful()) {
            return true;
        }

        Log::error('Discord API error', [
            'status' => $response->status(),
            'body' => $response->body()
        ]);

        return false;
    }

@RobertsP Thank you very much.
