# Digital Referral Prescription Project Welcome! This repository contains the key resources for using and integrating with eReferral (UHMEP). ### Documentation & Resources * **[eReferral Implementation Guide](https://build.fhir.org/ig/hl7-be/referral-uhmep/branches/)** * Holds the latest branch and version of the Implementation Guide. * Latest release: **[Release 2.0.0](https://build.fhir.org/ig/hl7-be/referral-uhmep/branches/release-2-0-0/en/)** > **Note:** The legacy eReferral API cookbook (`UHMEP_API_cookbook.pdf`) has been fully integrated into this Implementation Guide. This IG now supersedes the cookbook and serves as the single source of truth for integrators. > > The API error codes (`UHMEP_API_ErrorCodes.xlsx`) are also included in this Implementation Guide. > > For reference only, the last published version of the cookbook (v1.2) remains available here: [UHMEP_API_cookbook.pdf](https://github.com/smals-belgium/shared-digital-referral-prescription/blob/5addfea5179326c27abe0c7cee44d2a4b6cac2f3/UHMEP_API_cookbook.pdf)
