Based On https://github.com/camaraproject/ReleaseManagement/blob/main/documentation/API-Readiness-Checklist.md

Currently in Carrier Billing we have initial versions vX < 1. Therefore for these Fall24 Metarelease the proposal would be to have:

7 | Basic API test cases & documentation | O | M | M | M |   | link -- | -- | -- | -- | -- | -- | -- | --

To cover this issue I will be generating two PRs, in order to ease the review:

• One for Carrier Billing Payment
• Other for Carrier Billing Refund
