We are using CA API Gateway v9.3 with API Portal v4.2. I understand that with the earlier version of portal (v3.5) Monetization was an inbuilt feature where we could integrate with an external billing engine such as Recurly and generate invoices.
However this functionality does not seem to exist from v4.0 onwards. In this scenario, if we are looking to monetize our APIs could you please let us know what are the approaches we could make use of ? e.g. Capture the usage analytics from the database and feed it into an external billing system ?
Please let me know what options we can make use of at the moment.
