Before you connect
Questions about FastSpring.
The practical details behind the request, access and result.
Can I use FastSpring MCP to manage my subscriptions?
Yes, it lets you handle renewals, plan updates, and cancellations via your AI agent. You can manage the entire lifecycle of a subscription without leaving your chat interface.
How does FastSpring MCP help with customer support?
It allows your agent to fetch order details and generate secure 24-hour portal links instantly. This helps your team resolve access issues and payment inquiries much faster.
Can FastSpring MCP audit my store's products?
Yes, you can list all catalog products to verify your store's structural mapping. It's a great way to ensure your offerings are correctly configured across your global storefront.
Does FastSpring MCP handle fraud checks?
It retrieves cloud logs that show if customers successfully passed fraud filtering. This gives you visibility into order security without manual log digging.
How do I update customer info using FastSpring MCP?
You can use the Connector to provision JSON payloads that update hard customer records and CRM data. This keeps your records in sync with your latest updates automatically.
Can I use FastSpring MCP to see why customers are leaving?
Yes, it extracts rich churn reason metadata when you cancel a subscription. This provides the data you need to improve your retention strategies.
Can my agent check if an order passed fraud filtering in FastSpring?
Yes. Use the 'get_order_details' capability. The agent retrieves explicit cloud logs resolving if customers successfully passed fraud checks, providing you with the exact status of any transaction UUID.
How do I generate a customer login link via chat?
