fhir_authenticate {fhircrackr}

Create token for Authentication

Description

This function is a wrapper to create an httr::Token object for authentication with OAuth2/OpenID Connect. Internally, it calls httr::oauth_app(), httr::oauth_endpoint() and httr::oauth2.0_token() to create a token that can then be used in fhir_search.

Usage

fhir_authenticate(
  secret,
  key,
  base_url,
  access,
  authorize,
  query_authorize_extra = list()
)
