The assigningAuthority parameter applies only to patient record URLs. This parameter must be included in the URL query string if the specified patient ID is associated with an assigning authority in any source system.
For example:
https://app.domain:8080/overview/E20105242/eyJmIjpbXX0%253D/102?assigningAuthority=PAS1
For source systems that do not associate assigning authorities with patient IDs, the assigning authority parameter is ignored.
