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.
