Agent-to-Merchant Checkout APIs
PayPal's agent checkout APIs allow AI agents to initiate purchases on behalf of users at PayPal-accepting merchants. The agent creates an order, PayPal handles the payment authorization flow, and the merchant receives standard PayPal settlement.
💜
PayPal and Venmo Acceptance
Access both the PayPal network (400M+ accounts) and Venmo (80M+ users) through a single API integration. Agents can pay via whichever method the merchant or user prefers without separate integrations.
🧾
Invoicing
Create and send PayPal invoices programmatically. Agents can generate itemized invoices for services rendered, track payment status, send reminders, and handle partial payments — covering the full invoicing lifecycle.
🔄
Subscription Management
Create and manage recurring billing subscriptions on PayPal's platform. Supports plan management, subscriber upgrades/downgrades, pause/resume, and cancellation — useful for agents managing SaaS billing on behalf of operators.
