Error 422 on POST DocumentReference

[David]

Hi Cerner Team,

 

i'm trying to create a document reference using R4 API https://fhir.cerner.com/millennium/r4/foundation/documents/document-reference/#create.

However I receive a client error - HTTP 422.

The reason for this could be the mismatching Practitioner ID, that have to be used as author in the post request. In this thread https://groups.google.com/g/cerner-fhir-developers/c/AMY4HxK8aks/m/h4_Kc6ixCQAJ it is recommended to obtain the authorized user (Practitioner ID) using OpenID Connect. 

Is there any other way to get the Practitioner ID after a successful authorization? Can it be determined based on the access token on R4? This is possible according to the DSTU2 API for the same request https://fhir.cerner.com/millennium/dstu2/infrastructure/document-reference/#example-2.

Thank you,

David

You don't need to provide authenticator field if you have a Provider App.

https://fhir.cerner.com/millennium/r4/foundation/documents/document-reference/#body-fields

And for Author,

• Notes
  • Must contain only Practitioner references with valid millennium ids. Optional for system access. For provider access, only a single author can be provided, and it must be the authorized provider.

The Id of the authorized user should be found from the openId token.

Thanks,

Fenil
