Gumroad can connect with Documentero to automatically create professional documents whenever sales or subscription events happen. For example, when someone buys a product on Gumroad, Documentero can generate an invoice, receipt, or license file. If a subscription is canceled, it can issue a cancellation notice or update a customer record. This integration works through tools like API, Zapier, Make, or n8n, giving creators more control over the documents they send to customers.
