POST /convert/v1/fhirr4tocda
This operation converts a FHIR R4 bundle (including one from HL7-to-FHIR or Combine Bundles) into an aggregated CDA document.
The input for the CDA conversion is a FHIR R4 bundle for a single patient.
The output is an aggregated C-CDA R2.1 document in XML format.
The output format is in XML, so be sure to specify accept: application/xml
in your request header.
If the input data is invalid (such as improperly-formatted FHIR data), the request will return an error response (see Using the API). However, in many cases the Convert service can continue processing even when there are issues with the input data, such as missing fields or unexpected data types. In such cases, the invalid data will be omitted from the finished CDA document.
FHIR Bundles and CDA documents are verbose, so this just shows a small sample to illustrate how the data is structured. For a more complete example, try out the API in the Developer Portal Sandbox.
For example, a FHIR Patient
resource:
"resource": {
"resourceType": "Patient",
"id": "35b77437-425d-419c-90b5-af4bc433ebe9",
"name": [
{
"use": "official",
"family": "Smith",
"given": [
"John"
]
}
],
...
}
would be converted to a patient
node in the CDA XML:
<patient classCode="PSN" determinerCode="INSTANCE">
<name>
<given>John</given>
<family>Smith</family>
</name>
...
</patient>
