Fully Qualified Resource Identifier

Since Fasten includes resources from multiple EHR platforms, a {ResourceType}/{ResourceId} identifier is not guaranteed to be unique (eg. Encounter/1 could exist on multiple systems)

So Fasten uses the following Reference URI to identify the FHIR resources uniquely:


  • source_id is a UUID generated automatically when storing the SourceCredential in the database
  • source_resource_type is the FHIR Resource Type
  • source_resource_id is the FHIR Resource Identifier from the source EHR system
