SMART Health Card request

[Francesca Ricci-Tam]

Hello,

I'm working on a confidential patient-facing app (currently in development, in the Cerner sandbox) which includes .read scopes for Patient, Immunization, and Observation. I tried to test whether it could fetch a SMART Health Card for Nancy Smart, following the documentation in https://fhir.cerner.com/millennium/r4/foundation/other/health-cards/

I issued a POST request to 'https://fhir-myrecord.cerner.com/r4/ec2458f2-1e24-41c8-b71b-0e701af7583d/Patient/12724066/$health-cards-issue'

with the following headers:

        Accept: 'application/fhir+json',

        Authorization: `Bearer ${our accessToken redacted}`,

        'Content-Type': 'application/fhir+json',

and request body:

{

        resourceType: 'Parameters',

        parameter: [

                        {

                                name: 'credentialType',

                                valueUri: 'https://smarthealth.cards#health-card',

                        },

                        {

                                name: 'credentialType',

                                valueUri: 'https://smarthealth.cards#covid19',

                        },

                        {

                                name: '_since',

                                valueDateTime: '1990-04-01',

                        },

              ],

}

However, it fails with status code 400.

What needs to be corrected in the format?
Thanks,

Francesca Ricci-Tam

Hi Francesca,

Thanks for reaching out.

I believe the issue is that the body of your request is not properly formatted - the parameter elements are not encapsulated in quotes, only the parameter values.

When I query the same patient, on the same FHIR server, with the below with elements and values in quotes, I get a 200 and the payloads I expect:

{"resourceType": "Parameters", "parameter": [ { "name": "credentialType", "valueUri": "https://smarthealth.cards#health-card" }, { "name": "credentialType", "valueUri": "https://smarthealth.cards#covid19" }, { "name": "_since", "valueDateTime": "1990-04-01" } ] }
