LFPSE API validation guide (NHS England, 6 August 2023)

Summary

This guide published by NHS England & Improvement describes the validation rules relating to the LFPSE project, specifically around submitting an Adverse Event via the Adverse Event Application Programming Interface (API).

It covers several types of validation rules, which have been split into three sections.

1. Bespoke business validation rules which have been implemented based on the dependencies between responses and extensions that cannot be captured by the FHIR resource validation.
2. FHIR validation responses which may be returned from the API when native FHIR validation checks the submission body against the LFPSE FHIR profiles defined for an adverse event.
3. Invalid operations and similar responses which are external to validation of the submission, including responses pertaining to permissions, personal information and any other responses that do not fit into the two categories above.
