Hello, is there an API to look up an individual’s name and role when their UUID is know? Thank you. ---

Hhi @product1, This is not functionally offered by the e-RS as the data is not owned by us. For user and role information I think you would need to use [Spine Directory Service - LDAP API](https://digital.nhs.uk/developer/api-catalogue/spine-directory-service-ldap). There is also a new FHIR based API (that is still in Alpha) that allows you to retrieve basic Healthcare Worker information: [Healthcare Worker - FHIR API](https://digital.nhs.uk/developer/api-catalogue/healthcare-fhir-api). You would be best contacting the related teams for further information. Regards, Adam. ---

Although Catherine Ejiogu is no longer working on it, the Healthcare Worker API is now available for use - see [https://digital.nhs.uk/developer/api-catalogue/healthcare-worker-fhir](https://digital.nhs.uk/developer/api-catalogue/healthcare-worker-fhir) for details. ---

What if their UUID is not known? There seems to be no way to search for a worker’s UUID (or even know if they exist) based on their name, prefix, etc.
