The text discusses the impact of the European Union’s General Data Protection Regulation (GDPR), which has led to many companies updating their privacy policies and terms of service to comply with user rights such as the "right to erasure." It highlights how FusionAuth, a customer identity and access management solution, uses webhooks to handle user data deletion requests in compliance with GDPR. Webhooks in FusionAuth are event-driven notifications that can trigger actions within applications, such as deleting a user's data upon account deletion. The article provides a detailed guide on setting up a webhook in FusionAuth to listen for the 'user.delete' event, ensuring user data is removed before account deletion is completed. It also outlines how to configure webhooks using the FusionAuth UI, emphasizing the importance of transaction settings to ensure successful data deletion. Additionally, the post provides a code example using Node.js and Express to illustrate how to implement a webhook that verifies requests via an API key and deletes user data, thus maintaining synchronization between the application database and the FusionAuth user database. The article concludes by promoting FusionAuth’s features, including registration, login, and user management, and invites readers to learn more and engage with the community for support.
