Payment Service: PayPal Payouts

It processes POST requests with recipient email, amount, and currency, featuring robust validation, fraud protection, and error handling. Key nodes include Webhook (Payout Webhook) for input, Code (Security Processor) for validation and security checks, PayPal (PayPal Processor) for payout execution, and Code (Response Handler) for structured output. Ideal for finance or operations teams (3-10 staff) in e-commerce, freelancing, or SaaS ($500K-$5M revenue), it reduces payout processing time by 85% for 50-500 payouts monthly.\n\nSaves 8 hours/week on 50+ payouts, improving efficiency by 85%.
