Authentication

Step 1: Create Reddit Developer App

Go to https://www.reddit.com/prefs/apps/
Click "Create App" or "Create Another App"
Fill in:
- Name: Your app name
- Type: Select script for server-side automation
- Redirect URI: Your callback URL (e.g., https://yourapp.com/callback)
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',

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

Mock API for Development

// test/mocks/reddit-ads-mock.ts
import { rest } from 'msw';

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

Troubleshooting

Error	Cause	Fix
`401 Unauthorized`	Invalid/expired token	Refresh access token
`403 Forbidden`	Account not whitelisted	Contact Reddit Ads support
`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

## 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",

    "newBidMicros": number (optional, for ADJUST_BID),
