This software one of the core component of the ShareMyHealth project along with the "ShareMyHealth App" and "VerifyMyIdentity".
OAuth2.org is a tool for creating enterprise APIs for B-to-C and B-to-B applications. Any RESTful API can be managed through the gateway, including FHIR APIs. OAuth2.org can proxy FHIR servers such as Microsoft FHIR Server and the HAPI FHIR server. OAuth2.org can also conneect to Health Information Exchanges such as Intersystems HealthShare.
