Worked on enhancing the Invoicing API documentation within the getlago/lago-doc repository, focusing on clarifying webhook behavior for developers integrating payment features. Updated the Markdown-based documentation to explicitly state that the invoice.payment_overdue webhook is triggered when an invoice’s payment due date passes, and detailed the specific conditions under which an invoice remains flagged as overdue. This documentation improvement aimed to reduce ambiguity for API consumers, streamline integration efforts, and minimize support requests. The work demonstrated attention to detail in technical writing and a strong understanding of API integration challenges, leveraging skills in documentation and Markdown to improve developer experience.
