FAQ from A commerce-centric demo featuring Agent Development Kit with Paypal Agent Toolkit via MCPs

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.
