All static analysis findings are false positives. The skill is a documentation file (SKILL.md) containing legitimate PayPal payment integration code examples. The 'external_commands' patterns are markdown code blocks, not executable shell commands. The 'network' patterns are official PayPal API endpoints for payment processing. No security vulnerabilities detected.

Probiere diese Prompts

Basic PayPal button setup 
Help me add PayPal Smart Payment Buttons to my checkout page. I have a PayPal Business account and need to accept one-time payments in USD.
Subscription plan creation 
Create a monthly subscription plan for my SaaS product at $29/month. Include the API calls to create the plan and activate subscriptions.

Build an IPN webhook handler for my Express.js backend that verifies PayPal notifications and updates order status in my database.
Refund workflow automation 
Implement an automated refund system that processes customer refund requests, validates eligibility, and creates PayPal refunds with audit logging.

Bewährte Verfahren

  • Always verify IPN messages by posting back to PayPal before processing any payment notification
  • Use sandbox environment for testing and switch to production credentials only after thorough testing
  • Implement idempotent transaction processing to handle duplicate IPN notifications safely

Vermeiden

  • Processing IPN notifications without verification - allows fraudulent payment confirmations
  • Storing PayPal credentials in source code instead of environment variables
  • Mixing sandbox and production API endpoints or credentials in the same environment

Häufig gestellte Fragen

Do I need a PayPal Business account to use this skill?
Yes, you need a PayPal Business account to access the PayPal REST API and receive payments. Personal accounts cannot accept API-based payments.
What is the difference between sandbox and production mode?
Sandbox mode uses test credentials and fake transactions for development. Production mode processes real payments. Always test thoroughly in sandbox before switching to production.
How do I handle webhook failures?
Implement retry logic on PayPal side and ensure your webhook endpoint returns 200 status quickly. Log all webhook events for debugging and reconciliation.
Can I customize the PayPal checkout experience?
Yes, you can customize button styles, enable guest checkout, specify payment methods, and configure the return URL experience using the application_context parameters.
What happens if a subscription payment fails?
PayPal automatically retries failed payments based on your plan configuration. You can set payment_failure_threshold to specify how many retries before suspension.
How do I test refunds without using real money?
Use sandbox test accounts to create and capture test orders, then process refunds against those sandbox transactions. No real money is involved in sandbox mode.
