EMIS PFS integration

Has anyone got this API working in test for EMIS PFS api?

I’ve got most of the API calls working

but the middle two in the diagram below are returning errors

p.s. I think possibly I can achieve the same aim by integrating with NHS England PDS api.

It may be that I have to configure a nomination inside EMIS first and I think it’s either referring to

EPS Nominations (which is greyed out) or Preferred Pharmacy which is under Patient Actions
