Hi @RBatColumbus ,
We no longer have the documentation for unsupported versions of the API listed on the shopify.dev site, but if you are making requests to an unsupported version then the expected behaviour would be for Shopify to respond with the oldest stable version, which would be 2022-01.
The breaking changes for that version are included within their release notes, and since there were no other versions between the one you were using and the current oldest stable version those should be the only changes requiring immediate attention.
Cheers,
