There is also the topic of Search Parameters (if defined in the profile).

See from the Docs here and this related video - Working with FHIR Profiles in IRIS for Health (from Virtual Summit 2020).

Thank you Kari
I guess with a custom approach, you could also utilize for example the Vault REST API and use that when you want to access these kinds of credentials.

Hi @Kari Vatjus-Anttila 

I was wondering if since this question you ended up using Vault for this purpose somehow? or what other alternative you used?
