Stability Features Explained

Session Persistence

Sessions are automatically saved to Apify's KV Store and reused across runs:

• Session Key: Generated from your credentials (hashed for security)
• Storage: Encrypted cookies in Apify KV Store
• Expiry: 24 hours (then re-authenticates)
• Benefit: Reduces login frequency by ~90%, avoids security triggers

2Captcha Integration

Reddit uses reCAPTCHA for bot detection. When enabled:

1. Challenge is detected automatically
2. Captcha is sent to 2Captcha service
3. Solution is injected into the page
4. Process continues automatically

Setup:

1. Create account at 2captcha.com
2. Add funds ($3 minimum recommended)
3. Copy your API key
4. Add to twoCaptchaApiKey input

Sticky Proxy Sessions

Residential proxies with consistent IP assignment:

{
  "proxy": {
    "useApifyProxy": true,
    "apifyProxyGroups": ["RESIDENTIAL"],
    "apifyProxyCountry": "US"
  }
}

Method 1: Cookie-Based (Recommended)

How to Export Cookies:

1. Install "Cookie-Editor" browser extension
2. Log into Reddit in your browser
3. Click the extension icon
4. Export all cookies as JSON
5. Paste the JSON into the cookies field

Benefits:

• No login process (faster, more reliable)

• Works with 2FA-enabled accounts

Method 2: Username/Password

{
  "username": "your_reddit_username",
  "password": "your_password"
}

Note: May trigger security challenges. Cookie auth recommended.
