Frequently asked questions

What are the runtime requirements?

Python 3 with Google ADK 0.3.0+ (`google-adk==0.3.0`, `google-cloud-aiplatform==1.90.0`) and Node.js with npx for the MCP client. A PayPal sandbox account is required.

How do I set up the PayPal sandbox?

Register at developer.paypal.com to create apps. Each app provides a Client ID, Secret Key, and a sandbox account with test credit cards, addresses, and bank details for testing transactions.

Which PayPal APIs are used in this demo?

The demo tests and uses these APIs: `orders.create`, `orders.get`, `orders.capture`, `shipment.create`, `shipment.get`, `subscriptions.create`, `subscriptions.show`, `subscriptions.cancel`.

What are important API interdependencies?

Order capture succeeds only after the consumer completes payment via the returned URL. Subscriptions require a previously created product and plan. Disputes must be created by the human in the sandbox before a merchant can accept them. `list_transactions` has a delay.

Where does the agent’s data live?

The demo loads a hardcoded `user_profile` and `orders` dictionary from `paypal_mcp_agent/util.py`. Order data must correspond to actual records in the PayPal sandbox. No persistent database is used.
