Discord SDK API

Initialization

import { DiscordSDK } from '@discord/embedded-app-sdk';

const discordSdk = new DiscordSDK(clientId: string, options?: {
  disableConsoleLogOverride?: boolean;
});

// Wait for SDK to be ready
await discordSdk.ready();

Authentication

authenticate()

Requests user authorization and returns an access token.

const auth = await discordSdk.commands.authenticate({
  scopes: string[];  // OAuth2 scopes to request
  access_token?: string;  // Optional: re-use existing token
});

// Returns
interface AuthResponse {
  access_token: string;
  token_type: 'Bearer';
  expires_in: number;  // Seconds until expiration
  scopes: string[];
  user: {
    id: string;
    username: string;
    discriminator: string;
    avatar: string | null;
    public_flags: number;
  };
}

Available Scopes:

• identify - Read user profile (id, username, avatar)

• email - Read user email address

• guilds - See servers user is in

• guilds.members.read - Read user's guild member data

authorize()

Similar to authenticate() but doesn't return user data.

const { code } = await discordSdk.commands.authorize({
  client_id: string;
  response_type: 'code';
  scope: string;  // Space-separated scopes
  state?: string;
});

User Methods

Get Current User

// Using Discord SDK
const user = await discordSdk.commands.getUser();

// Or via REST API
const response = await fetch('https://discord.com/api/v10/users/@me', {
  headers: {
    'Authorization': `Bearer ${access_token}`
  }
});
const user = await response.json();

User Object:

interface DiscordUser {
  id: string;  // Snowflake ID
  username: string;
  discriminator: string;  // "0" for new usernames
  global_name: string | null;  // Display name
  avatar: string | null;  // Avatar hash
  bot?: boolean;
  system?: boolean;
  mfa_enabled?: boolean;
  banner?: string | null;
  accent_color?: number | null;
  locale?: string;
  verified?: boolean;
  email?: string | null;  // Requires 'email' scope
  flags?: number;
  premium_type?: number;
  public_flags?: number;
}

Guild (Server) Methods

Get User Guilds

const response = await fetch('https://discord.com/api/v10/users/@me/guilds', {
  headers: {
    'Authorization': `Bearer ${access_token}`
  }
});
const guilds = await response.json();

Guild Object:

interface DiscordGuild {
  id: string;
  name: string;
  icon: string | null;
  owner: boolean;
  permissions: string;
  features: string[];
}

Activity Context

Get Instance Info

Information about the current Discord Activity session.

const instanceId = discordSdk.instanceId;  // Unique instance identifier
const channelId = discordSdk.channelId;    // Current channel ID
const guildId = discordSdk.guildId;        // Current guild ID

Get Participants

Get list of users currently in the Activity.

const participants = await discordSdk.commands.getInstanceConnectedParticipants();

interface Participant {
  id: string;
  username: string;
  discriminator: string;
  avatar: string | null;
  flags: number;
}

Authentication Methods

Method 1: Discord Activity OAuth

For apps running inside Discord Activity.

import { DiscordSDK } from '@discord/embedded-app-sdk';

const discordSdk = new DiscordSDK(clientId);
await discordSdk.ready();

// Authenticate with Discord
const { access_token } = await discordSdk.commands.authenticate({
  scopes: ['identify', 'email', 'guilds']
});

// Exchange for AeThex token
const response = await fetch('/api/discord/activity-auth', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({ accessToken: access_token })
});

const { aethexToken, user } = await response.json();

// Use AeThex token for subsequent requests
fetch('/api/games', {
  headers: { 'Authorization': `Bearer ${aethexToken}` }
});

Method 2: OAuth Redirect Flow

For standard web applications.

// Step 1: Redirect to OAuth start endpoint
window.location.href = '/api/discord/oauth/start?action=login';

// Step 2: User authorizes on Discord

// Step 3: Discord redirects to /api/discord/oauth/callback
// Step 4: Backend processes callback and redirects to dashboard
// Step 5: User is logged in with session cookies

Method 3: Account Linking

For linking Discord to existing AeThex account.

// In your frontend (user must be logged in)
async function linkDiscordAccount() {
  // Create linking session
  const response = await fetch('/api/discord/create-linking-session', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${aethexToken}`,
      'Content-Type': 'application/json'
    }
  });
  
  const { sessionToken } = await response.json();
  
  // Redirect to Discord OAuth with session token
  const state = btoa(JSON.stringify({
    action: 'link',
    sessionToken,
    redirectTo: '/dashboard?tab=connections'
  }));
  
  const oauthUrl = `https://discord.com/api/oauth2/authorize?` +
    `client_id=${discordClientId}&` +
    `redirect_uri=${encodeURIComponent(callbackUrl)}&` +
    `response_type=code&` +
    `scope=identify%20email%20guilds&` +
    `state=${state}`;
  
  window.location.href = oauthUrl;
}

Method 4: Bot Verify Command

For Discord bot users to link accounts.

// Discord bot generates code (server-side)
import { generateVerificationCode } from '@aethex/bot-utils';

const code = generateVerificationCode(discordUserId);
// Stores: { code: '123456', discord_id: '...', expires_at: ... }

// User visits verification page
// GET /discord-verify?code=123456

// Frontend auto-submits code
const response = await fetch('/api/discord/verify-code', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    code: '123456',
    discordId: discordUserId,
    username: 'user#1234'
  })
});

if (response.ok) {
  // Account linked! Redirect to dashboard
  window.location.href = '/dashboard?tab=connections';
}

Event Handling

Activity Events

discordSdk.subscribe('READY', () => {
  console.log('Activity is ready');
});

discordSdk.subscribe('VOICE_STATE_UPDATE', (voiceState) => {
  console.log('Voice state changed:', voiceState);
});

discordSdk.subscribe('SPEAKING_START', ({ userId }) => {
  console.log(`${userId} started speaking`);
});

discordSdk.subscribe('SPEAKING_STOP', ({ userId }) => {
  console.log(`${userId} stopped speaking`);
});

// Activity participants joined/left
discordSdk.subscribe('ACTIVITY_INSTANCE_PARTICIPANTS_UPDATE', (participants) => {
  console.log('Participants updated:', participants);
});

Discord Bot Commands

If you have a Discord bot, register these commands for better user experience.

/verify Command

Links Discord account to AeThex.

Registration:

{
  name: 'verify',
  description: 'Link your Discord account to AeThex',
  options: []
}

Handler (bot code):

async function handleVerifyCommand(interaction) {
  const discordUserId = interaction.user.id;
  const discordUsername = `${interaction.user.username}#${interaction.user.discriminator}`;
  
  // Generate 6-digit code
  const code = Math.floor(100000 + Math.random() * 900000).toString();
  
  // Store in database with 5min expiry
  await db.verification_codes.insert({
    code,
    discord_id: discordUserId,
    discord_username: discordUsername,
    expires_at: new Date(Date.now() + 5 * 60 * 1000)
  });
  
  // Send ephemeral message with link
  await interaction.reply({
    content: `🔗 Link your account:\n\n` +
             `Click: https://aethex.dev/discord-verify?code=${code}\n\n` +
             `Or enter code manually: **${code}**\n\n` +
             `⏱️ Code expires in 5 minutes.`,
    ephemeral: true
  });
}
