Batch create

Create multiple Patient and/or ServiceRequest resources in one request using FHIR Batch operation. The batch operation supports linking resources together using temporary "urn:uuid" identifiers.

For example, this request will create a Patient and ServiceRequest, even though the Patient ID is not known in advance:

curl -X POST https://api.kit.com/fhir/R4/ \
    -H "Authorization: Bearer $MY_ACCESS_TOKEN" \
    -H "Content-Type: application/fhir+json" \
    -d '{
