Accessing API Resources Used in Earlier Product Versions

API resources that were available in earlier versions of Oracle Billing Insight are backward-compatible, and can still be accessed with one modification in their usage.

To access an API resource from an earlier product version

• In the URL, replace the ebillingrs/rs/ path before the resource with rs/api/v1/.

  For example, in version 6.2, the following sample URL got a list of billing hierarchies for a user:

  http://myhost.example.com:7017/ebillingrs/rs/hierarchies/billing

  To use the 6.2 hierarchies/billing resource in version 7.0, change the URL as follows:

  http://myhost.example.com:7017/rs/api/v1/hierarchies/billing

  NOTE:  Version 7.0 APIs are accessed with rs/api/v2 in the URL path.
