Bank of Melbourne

Bank of Melbourne is a Victorian retail and business banking brand operated by Westpac Banking Corporation (ASX code WBC) as part of the Westpac Group. The original Bank of Melbourne was acquired by Westpac in 1997 and the brand was relaunched in 2011; today it operates under the St.George Bank banking authority within Westpac and is NOT a customer-owned mutual - it is a division of a publicly listed, APRA-regulated authorised deposit-taking institution (ADI). As an accredited Consumer Data Right (CDR) data holder, Bank of Melbourne exposes a public, unauthenticated Product Reference Data (PRD) API that conforms to the Australian Consumer Data Standards, confirmed live on shared Westpac Group infrastructure at digital-api.bankofmelbourne.com.au. Consumer data sharing runs through the regulated CDR / Accredited Data Recipient (ADR) model using OAuth2 / OpenID Connect (FAPI) authorization; the bank does not run a broader third-party developer portal.

Bank of Melbourne publishes 5 APIs on the APIs.io network, including CDR Product Reference Data API, CDR Accounts & Balances API, CDR Transactions API, and 2 more. Tagged areas include Financial, Banks, Open Banking, CDR, and Consumer Banking.

Regulatory Posture applies to this provider. Its tags matched the Banking & Open Finance regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/bank-of-melbourne: open an issue to ask a question, or submit a pull request to add artifacts.
