What are some security considerations and best practices when exposing a GraphQL API to the public internet?

Strong authentication and authorization procedures, input validation and sanitization, and limitations on query complexity and depth are essential when opening a GraphQL API to public access. It’s also important to use API monitoring and rate-limiting techniques to identify and stop abusive traffic patterns. Additionally, keep the GraphQL schema secure and don’t reveal sensitive data in error messages in order to protect against information leakage and potential exploitation.
