Hi everyone,

Different versions of OpenAPI v2/v3 have different z/OS Connect features and tools.

Is there a matrix that shows these differences at a glance?

Thanks in advance.

Rest regards,

Don't think so

but you may find this IBM zOS Connect FAQ useful in understanding about OpenAPI3 

https://www.ibm.com/docs/en/zos-connect/zos-connect/3.0?topic=introduction-faqs

https://www.ibm.com/docs/en/zos-connect/zos-connect/3.0?topic=concepts

In summary, zOS Connect OpenAPI2 and OpenAPI3 both provide a way to create REST APIs to access CICS/IMS/Db2 on zOS

OpenAPI2 GUI runs in Eclipse on Windows only

OpenAPI3 GUI is called the designer and is a container that can run on x86 or s390 ( even zCX on zOS )

The OpenAPI3 designer provides many functions you can use to do data manipulation, the older OpeAPI2 GUI cannot do this 

If you are a new site for zOS Connect, you should use OpenAPI3

Thank you for your reply, the available z/OS assets also seem to be different. I found the matrix very helpful.
