PayPal Integration Guide

Go to paypal.com/business and sign up for a Business account (free). Verify your email and complete identity verification.

If testing, also create a sandbox account at developer.paypal.com → Sandbox → Accounts.

This is the email address you use to log in to your PayPal Business account.

For sandbox testing, use the seller sandbox email shown in developer.paypal.com → Sandbox → Accounts.

'paypal_email'   => 'your-real-paypal@email.com',
'paypal_sandbox' => false,  // Change to false for LIVE

Keep paypal_sandbox => true while testing. Only set to false when ready to go live.

1. Log in to PayPal → Account Settings
2. Find Notifications → Instant Payment Notifications
3. Click Update → Choose IPN Settings
4. Set Notification URL to: https://yoursite.com/wp-security-scanner.php?action=ipn
5. Select Receive IPN messages (Enabled) then Save

The license key is sent via PHP mail(). Test it works on your host. If emails go to spam:

• Set up SPF/DKIM DNS records for your domain
• Or update inc/email.php to use PHPMailer with SMTP credentials

1. Keep paypal_sandbox => true
2. Register a new user → you'll be redirected to PayPal Sandbox
3. Log in with a buyer sandbox account
4. Complete the payment — IPN fires → license key emailed
5. Check DB: wps_payments status=completed, wps_licenses has new row

1. Set 'paypal_sandbox' => false in inc/config.php
2. Update 'paypal_email' to your real PayPal business email
3. Enable IPN in your live PayPal account (same steps as Step 4)
4. Make a real test purchase to confirm everything works end-to-end
