## Extension: NDH Dynamic Registration

Official URL: http://hl7.org/fhir/us/ndh/StructureDefinition/base-ext-dynamicRegistration | Version: 2.0.0-current
Standards status: Trial-use | Maturity Level: 4 | Computable Name: DynamicRegistration

Dynamic registration within a trust framework refers to a process where clients can register with a server or service provider dynamically and securely at runtime, rather than being pre-registered manually. This approach is often used in environments where scalability, flexibility, and security are crucial. Currently, dynamic registration is used in SMART and UDAP.
