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',

Important Notes

• Events must occur within last 7 days to be processed
• Maximum 500 events per batch request
• Include click_id when available for better attribution
• Use test_mode: true for testing without affecting campaigns

Custom Audiences

Audience Types

Create Customer List Audience

interface CustomAudienceCreate {
  name: string;
  type: 'CUSTOMER_LIST';
  description?: string;
  users: Array<{
    email_sha256?: string;
    maid_sha256?: string; // Mobile Advertising ID
  }>;
}

// Create audience from customer emails
const audience: CustomAudienceCreate = {
  name: 'High Value Customers Q4 2024',
  type: 'CUSTOMER_LIST',
  description: 'Customers with LTV > $500',
  users: customerEmails.map(email => ({
    email_sha256: hashPII(email)
  }))
};

const result = await client.createCustomAudience(audience);

Minimum Audience Size

• 1,000 matched users minimum to be usable for targeting
• Match rates displayed as ranges for privacy

Reporting

Report Request

interface ReportRequest {
  start_date: string; // YYYY-MM-DD
  end_date: string; // YYYY-MM-DD
  level: 'ACCOUNT' | 'CAMPAIGN' | 'AD_GROUP' | 'AD';
  metrics: string[];
  dimensions?: string[];
  filters?: {
    campaign_ids?: string[];
    ad_group_ids?: string[];

└─────────────────────────────────────────────────────────────────┘

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');
}

  console.log(`Created campaign: ${campaign.id}`);

  // 2. Create Ad Group with targeting
  const adGroup = await client.createAdGroup({

  console.log(`Created ad: ${ad.id}`);

  return { campaign, adGroup, ad };
}

// Usage
const result = await createRedditAdCampaign(client, {
  campaignName: 'Product Launch - Jan 2025',
  dailyBudget: 50, // $50/day
  targetSubreddits: ['technology', 'gadgets', 'programming'],

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

  rest.post('https://www.reddit.com/api/v1/access_token', (req, res, ctx) => {

- Min impressions for decisions: ${this.config.minImpressions}
- Budget scale factor for winners: ${this.config.budgetScaleFactor}x

## 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 recommenda
