OPA = Oracle Policy Automation
Oracle Policy Automation is an end-to-end solution for capturing, managing, and deploying complex legislation and other document-based policies across channels and processes.

One creates process models in OPA - these contain the business logic - from the docs -
Essentially we will pass in a payload to OPA and it will process it via the policy model I select, then return a result.
As an OPA neophyte, I have worked out that it has two main parts -
1. the Policy Modeling Tool - which you download to a Windows machine.
This is where you design the policies.
2. OPA Hub - for policy model management and deployment.
A colleague has kindly created a simple policy model for me - OIC_test.
The policy is very simple -
The order will be approved, once I pass in those 3 attributes.
As you can see, he has checked Web Services - Assess - so what is that?
From the docs -
OIC_test will simply assess an incoming purchase order and return an approval value -
true or false.
Test is the Invoke of OPA.
The OPA Connection is defined as follows -
The Access Token URI = OPA Hub URL/opa-hub/api/auth
Note the OAuth requirements - for this, some preparatory steps in OPA are required -
Full setup info -
OPA Adapter Guide here
Supplementary OPA doc for Integration here
OPA REST API here
Now to the mapping -
Let's look at it in detail -
OPA processes cases, think of a social welfare entitlement case and the complex rules
that need to be applied to it.
As already explained, my simple example processes a purchase order case.
Note the outcomes field - This structure contains the case field(s) which will hold the response from OPA. In my simple example, this is the order_approved field. Again, as already mentioned, OPA will return a value of true or false.
The orderId, order_date and order_value fields are all related to the purchase order I will be validating.
The final field, id, is the case unique id field and needs to be set. I just set it to the orderId.
Now to the response mapping -
As you can see, I map the order_approved field to my result field.
Now to testing, via Postman -
Very succinct!

Oracle Policy Modeling is a desktop application used to build interactive interviews based on business requirements, complex policy and legislation. It can be used for modeling:
- Policy eligibility
- For example, determining whether a contact is eligible for a benefit, permit, loan, discount, license, product upgrade or parental leave.
- Calculations
- For example, determining a contact’s rate of benefit, allowance, deduction, tax, discount, waiting period or follow-up.

From the docs -
The generic assess service uses supplied data to determine one or more outcomes,
can work out what additional data is needed to reach a conclusion,
and provides reports on how decisions were reached.
OIC_test will simply assess an incoming purchase order and return an approval value -
true or false.
Creating the OIC Integration with OPA
I create the following integration in OIC -
