How do I get my Gumroad Access Token?

Log in to your Gumroad account, navigate to **Settings > Advanced**, and scroll down to the 'Application' section to create an application or generate a personal access token.

Can I verify customer license keys through this integration?

Yes! Use the `verify_license` tool by providing the `product_id` and the `license_key` provided by the customer. The agent will confirm if the key is valid and how many times it has been used.

Does this integration support processing refunds?

Yes, you can use the `refund_sale` tool with a specific sale ID to initiate a refund directly from your AI agent.

Is my sales data secure?

Absolutely. The integration uses OAuth 2.0 Bearer tokens and communicates only with Gumroad's official API over HTTPS. Your token is encrypted and stored securely in the Vinkius Cloud.
