Get Product and Get Product Detail versioning

Question

With the introduction of v4 for Get Product Detail,  is the expectation that Data Holders (DHs) will not change their current response schema for Get Products?
The CDS right now indicates that V3 remains the highest version of Get Products, but the response schema indicates that DHs are meant to respond with BankingProductV4? Is this intentional?

Answer

The standards show version 4 (and the relevant response schema) for Get Product Detail. For the schema related to Get Product v3, you can click on the link to v3 listed in the obsolete versions. This shows the previous version of the response schema.

Question

As per the standards the latest version for Get Products is v3, but clicking through the schema leads to BankingProductV4. The endpoint version schedule also shows that only Get Product Detail has been incremented to v4.

Are the standards suggesting that Get Products endpoint still remains at V3 but the response should be with BankingProductV4 schema, and only Get Product Detail endpoint is upgraded version 4? Or have both endpoints been upgraded to v4?

Answer

With respect to Get Products there was no breaking change introduced in relation to the array list of additionalOverviewUris. The Get Product Detail API introduced new enumerations for product feature types in release 1.15.0. This extension of the enumeration set for featureType in the Get Product Details BankingProductFeatureV2's array introduced a breaking change for clients. As a result, Get Product Details was versioned to v4 however Get Products remained v3.
