Hello we are looking at downloading prescriptions using [https://digital.nhs.uk/developer/api-catalogue/eps-fhir-dispensing-api#post-/FHIR/R4/Task/$release](https://digital.nhs.uk/developer/api-catalogue/eps-fhir-dispensing-api#post-/FHIR/R4/Task/$release).

As part of downloading prescription we get a signature is there a guide anywhere that says how we should verify if that signature is valid or not?

We would then pass if the signature is valid or not downstream in our systems to be delt with depending on if it is valid or not.

We have just found this on the nhs docs. Does this mean we can assume the signature on a prescription is always valid?

Using the EPS FHIR Dispensing API, the prescription signature will be validated prior to download so your system doesn’t need to
