Welcome to Horizon Interoperability
Developer Portal

Enabling APIs to leverage access to a patient’s clinical and administrative data.

Data APIs available

APIs for interoperability comprised of USCDI clinical data, CARIN administrative data, Da Vinci Formulary Drug data and Da Vinci Provider Directory data

How Do I Start?

The APIs of Horizon Connected Interoperability Solution provide the basis for building healthcare applications, such as mobile, that deliver HL7® FHIR® data to members and providers on demand. Example of application use cases can include viewing test results, checking on medications, and reviewing recent office visits.

Our APIs allow access to clinical, administrative and formulary drug plan information about a patient, as well as provide detailed provider directory information. Applications will securely interact with this data on behalf of the patient in order to deliver patients real-time access to their healthcare data.

For a set of data sharing principles and best practices for healthcare applications, read the CARIN code of conduct.

To get started with the Developer Portal, read the Developer Portal User Guide.

Our APIs

Administrative

APIs that will connect a patient to their administrative data such as claim, explanation of benefits, member and coverage information that supports the Carin Consumer Directed Payer Data Exchange implementation guide.

Clinical

APIs that will connect a patient to their clinical data, such as lab or diagnostic results, medications, consultation and
referral notes and more that support the USCDI implementation guide.

Provider Directory

APIs that will give detailed information about a payer’s network of physicians and facilities with the goal of connecting patients to care providers that supports the Da Vinci Payer Data Exchange Plan Net Directory implementation guide.

Drug Formulary

APIs that will allow a patient to explore their drug plan and understand drug tiers and cost sharing information that support the Da Vinci Payer Data Exchange US Drug Formulary implementation guide.

Example Endpoint Call

As an example, you can obtain member profile data based on tenant enrollment ID, subscriber ID and profile group by making an API endpoint call to
/profile-fxi-data/get-member-tenantenrollmentid().

On the API page, you can test-execute this operation by clicking the “Try it” link and following the instructions. In this case, you’ll receive an example set of member profile data in the returned response.

GET /member/{tenantenrollmentid}
{
    "type": "object",
    "properties": {
        "tenantEnrollmentId": {
            "type": "string",
            "description": "Unique ID assigned."
        },
        "subscriberId": {
            "type": "string",
            "description": "The subscriber's ID."
        },
        "profileGroups": {
            "$ref": "#/definitions/profileGroups"
        }
    }
}
