Token introspection is a key process in securing modern FHIR APIs by validating access tokens from external identity providers.
The article covers the fundamentals of authentication, authorization, and token introspection in FHIR. It details different token validation methods supported by Aidbox, including secret-based, JWKS URI, and direct cryptographic key configurations. Readers will learn how token introspection works in practice and see best practices for managing token security in healthcare applications.
Why it’s beneficial to readers
Understanding token introspection equips developers and DevOps teams with the knowledge to secure their FHIR servers effectively while embracing existing identity infrastructure. This reduces system complexity, improves security, and prevents costly re-architecting of authentication workflows.
