Registration
Developers and providers who are interested in accessing the API can register for access by visiting the official website at https://www.udap.org/udap-dynamic-client-registration.html. The registration process allows individuals and organizations to obtain the necessary credentials and permissions to utilize the API and its associated services.
By completing the registration, developers gain access to a range of resources and tools that enable them to integrate the API into their applications, platforms, or services. This includes documentation, code samples, and technical support to assist with the implementation and utilization of the API's features.
The registration process typically involves providing relevant information such as name, email address, organization details, and a brief overview of the intended use case for the API. Upon successful registration, developers and providers will receive the required API keys or authentication tokens, which are essential for establishing secure and authorized connections to the API endpoints.
The platform at https://www.udap.org/udap-dynamic-client-registration.html serves as a central hub for managing API access, ensuring that developers and providers have the necessary resources and support to leverage the functionality offered by the API.
Connecting to a FHIR Datasource
Client applications can connect to production FHIR data sources enabled by EMR Direct using the FHIR Open API at the following URL:
https://api.healthtogo.me/fhir/[fhir-version]/[datasource-name]/
The URL immediately above is a FHIR endpoint URL that is used to retrieve resources from the data holder's system. It is not a website that serves HTML for a regular browser like Chrome; instead, it is intended to be accessed by a FHIR client that is following the Interoperability Engine Open API documentation for 3rd party client application developers available at the HealthToGo App Studio site. Information about a variety of additional app registration options is also available there. Developers who are unfamiliar with the SMART user/... clinical scopes may also wish to review this resource. To obtain the datasource-name and supported FHIR version(s), please contact the healthcare organization directly.
Data holders may register for an account used to publish their health data as FHIR resources here: https://www.emrdirect.com/subscribe-developer.
Determining the baseOAuthURL
The baseOAuthURL is used to access the token, authorization, or registration endpoints. The baseOAuthURL for EMR Direct Interoperability Engine FHIR endpoints is of the form:
https://api.healthtogo.me/oauth/[datasource-name]/
The baseOAuthURL can be derived from the FHIR endpoint for a given datasource, which is of the form:
https://api.healthtogo.me/fhir/[fhir-version]/[datasource-name]/
Please contact connect@golunar.com directly for the datasource-name if it cannot be located in the Interoperability Engine FHIR endpoint directory.
