[Openid-specs-authzen] A question on resource identifiers for resources that do not exist yet

Thu May 8 15:33:17 UTC 2025

You do have a resource ID - it’s the product id. The amount may be a condition of the product type - determined by the product id. But I really don’t think it this would actually be a real life check as there would be a pile of other criteria including the customer, term and other loan optionality that would be customer based.

well it does bring up the rather interesting case of create

 create doesn't have. resource ID

Couldn't the resource be a higher level entity? e.g. the Region? the customer? the bank branch? If it's B2B, the organization?

Sounds to me that resource Id shouldn't be mandatory, or that the resource Id is for the collection of loans. Passing a resource ID of 0 works, but that just feels like a magic value.

hmmm

surely customer is part of the resource?  and a create can simply use a resource ID of 0 or -1. or null

Hi all,

Interesting use case from EIC: I want to write a policy that determines how a loan-to-be can be created.

Managers can create a loan for a customer in their region up to their max allowed amount for the employee (and/or customer).

The request would then be:

  *   Can Alice the employee create loan with amount 1234?

In this type of request, because the loan hasn't been created we do not have a  loan ID or resource ID. But, because AuthZEN makes the resource ID mandatory in the evaluation API, what approach do we want to recommend?
