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',

    body: new URLSearchParams({

Naming Conventions

Campaign:  [Objective] - [Product/Brand] - [Date Range]
           Example: TRAFFIC - ProductX - Q1-2025

Ad Group:  [Targeting Type] - [Audience Description]
           Example: Subreddits - Tech Enthusiasts

Ad:        [Headline Type] - [Creative Version]
           Example: Problem-Solution - Image-A

Rate Limiting

• 1 request per second limit
• Implement exponential backoff for retries
• Batch operations where possible

async function rateLimitedRequest<T>(
  fn: () => Promise<T>,
  retries = 3
): Promise<T> {
  for (let i = 0; i < retries; i++) {
    try {
      await new Promise(resolve => setTimeout(resolve, 1000)); // 1 second delay
      return await fn();
    } catch (error: any) {
      if (error.status === 429 && i < retries - 1) {
        const delay = Math.pow(2, i) * 1000;
        await new Promise(resolve => setTimeout(resolve, delay));
        continue;
      }
      throw error;
    }
  }
  throw new Error('Max retries exceeded');

Testing

Test Checklist

• OAuth flow completes successfully
• Token refresh works before expiry
• Campaign creates with correct budget
• Ad group targeting is applied correctly
• Ad creative displays properly
• Conversion events tracked (use test_mode)
• Reports return expected metrics
• Rate limiting handled gracefully
• Error responses handled properly

429 Too Many Requests	Rate limit exceeded	Implement backoff, slow down
400 Bad Request	Invalid payload	Check required fields, data types
Audience too small	< 1,000 matched users	Add more users to audience

- Min impressions for decisions: ${this.config.minImpressions}

## Your Task
Analyze each ad/ad group and recommend ONE action per item:
1. PAUSE - Poor performers (low CTR, high CPA, no conversions after sufficient impressions)
2. SCALE - Winners (high CTR, low CPA, good ROAS) - increase budget
3. ADJUST_BID - Moderate performers - suggest bid adjustment
4. KEEP - Insufficient data or acceptable performance
5. ROTATE_CREATIVE - Good targeting but ad fatigue (declining CTR over time)

Return a JSON array of recommendations:
[
  {
    "adId": "string",
    "adGroupId": "string",
    "action": "PAUSE|SCALE|ADJUST_BID|KEEP|ROTATE_CREATIVE",
    "reason": "Brief explanation",
    "newBidMicros": number (optional, for ADJUST_BID),
