Oystehr v1.27 - August 7 2025

App + IAM Service Changes

• The Update User (opens in a new tab) and Update M2M Client (opens in a new tab) endpoints now support replacing the actor's FHIR Profile. Learn more (opens in a new tab).
• Similar to the user/me endpoint (opens in a new tab), an m2m/me (opens in a new tab) endpoint has been added to allow for M2M Clients to fetch information about themselves.

FHIR

• FHIR batch and transaction operations now support optimistic locking. While optimistic locking was already supported in the FHIR service for PUT and PATCH operations (opens in a new tab), this change adds support for optimistic locking to be used in batch and transaction bundles as well. To use this feature, set ifMatch (opens in a new tab) on Bundle.entry.request (opens in a new tab) to the ETag of the resource you are trying to update. This feature is also supported in the TypeScript SDK.

eRx

• The eRx service now supports enrollment of non-prescribing Users. Non-prescribing users can run drug interaction checks and order medications on behalf of prescribing users. All prescriptions ordered by non-prescribing users must be approved by a prescribing user before they are sent to a pharmacy. Learn more (opens in a new tab).
