Authentication

Step 1: Create Reddit Developer App

1. Go to https://www.reddit.com/prefs/apps/ 2. Click "Create App" or "Create Another App" 3. Fill in:

• **Name:** Your app name
• **Type:** Select `script` for server-side automation
• **Redirect URI:** Your callback URL (e.g., `https://yourapp.com/callback`)

4. Note your **Client ID** (under app name) and **Client Secret**

Step 2: Authorization Flow

// Node.js OAuth2 flow
const REDDIT_CLIENT_ID = process.env.REDDIT_ADS_CLIENT_ID;
const REDDIT_CLIENT_SECRET = process.env.REDDIT_ADS_CLIENT_SECRET;
const REDIRECT_URI = 'https://yourapp.com/callback';

// Step 1: Generate authorization URL
function getAuthorizationUrl(state) {
  const scopes = 'adsread,adsedit,history';
  return `https://www.reddit.com/api/v1/authorize?` +
    `client_id=${REDDIT_CLIENT_ID}` +
    `&response_type=code` +
    `&state=${state}` +
    `&redirect_uri=${encodeURIComponent(REDIRECT_URI)}` +
    `&duration=permanent` +
    `&scope=${scopes}`;
}

// Step 2: Exchange code for tokens
async function getAccessToken(authorizationCode) {
  const credentials = Buffer.from(
    `${REDDIT_CLIENT_ID}:${REDDIT_CLIENT_SECRET}`
  ).toString('base64');

  const response = await fetch('https://www.reddit.com/api/v1/access_token', {
    method: 'POST',
    headers: {
      'Authorization': `Basic ${credentials}`,
      'Content-Type': 'application/x-www-form-urlencoded',
      'User-Agent': 'YourApp/1.0.0'
    },
    body: new URLSearchParams({
      grant_type: 'authorization_code',
      code: authorizationCode,
      redirect_uri: REDIRECT_URI
    })
  });

  return response.json();
  // Returns: { access_token, refresh_token, expires_in, scope }
}

// Step 3: Refresh token when expired
async function refreshAccessToken(refreshToken) {
  const credentials = Buffer.from(
    `${REDDIT_CLIENT_ID}:${REDDIT_CLIENT_SECRET}`
  ).toString('base64');

  const response = await fetch('https://www.reddit.com/api/v1/access_token', {
    method: 'POST',
    headers: {
      'Authorization': `Basic ${credentials}`,
      'Content-Type': 'application/x-www-form-urlencoded',
      'User-Agent': 'YourApp/1.0.0'
    },
    body: new URLSearchParams({
      grant_type: 'refresh_token',
      refresh_token: refreshToken
    })
  });

  return response.json();
}
