Introduction to API Security | Postman Intergalactic

Join us for an informative one-hour webinar focused on API security, tailored for beginners. In this session, you will gain valuable insights into the OWASP API Security Top 10 risks and learn how to effectively detect vulnerabilities in GraphQL-powered APIs using Postman. Our webinar will explore key topics such as Server-Side Request Forgery, Broken Object property Level Authorization, and unsafe consumption of APIs that could expose sensitive business flows.

Whether you're a developer, security professional, or simply interested in API security, this beginner-friendly webinar is designed to equip you with the knowledge and skills to build secure and reliable APIs using Postman.
