Best Practice for Sending Credit Memo's to Customers via EDI?

Summary:

We are a supplier to a customer, and we have a requirement to send credit memos to our customer via EDI. This would include credit memos raised through the dispute flow, and returns order credit memos.

I wanted to understand, what is the Oracle standard way of sending credit memos to customers from Fusion? I'm struggling to find documentation for this particular scenario.

One idea we've had is to create a custom ESS job, that would receive the customer name and credit memo number. This would then be passed to an OIC integration to return the credit memo details via API, which we would then construct a message to be sent to our EDI provider. I've found the REST & SOAP API's to do this, however before beginning any development I wanted to check if there was a more standard approach to take?
