PayPal REST API
Mature REST API for payments, subscriptions, invoicing, and disputes; no API access fee, only per-transaction percentage
Solid choice for most workflows
You need to add reliable one-time payments and checkout flows to your agent-powered storefront without building payment processing from scratch
Rock-solid for global PayPal users; expect 2-3% fees per transaction, mature docs with samples, but requires redirect flows and buyer approval steps
You want recurring billing or subscription management in your SaaS agent without juggling multiple payment processors
Handles complex billing schedules well with no upfront fees; quirks include mandatory buyer confirmation on first payment and regional availability limits
You need to send professional invoices and track payments in your service agent without email templates or manual accounting
Excellent for B2B/service billing; expect high delivery rates but requires PayPal account linkage for payers
Redirect-based buyer approval required
All flows need redirect to PayPal for buyer authentication/approval - no fully headless checkout without custom frontend handling
Per-transaction fees only after volume
No API access fees but 2.9% + $0.30/transaction (US); costs scale with volume - monitor seller_protection eligibility to avoid chargebacks
