We have general question to check if portal supports SSO ? and how to setup this functionality?
Is swagger v2 or v3 supported in Portal 3.5?

Release : 3.5

Component : API PORTAL

The following link outlines how to setup SAML SSO in Portal 3.5

API Portal 3.5 only supports WADL and RAML files. But swagger files can be formatted in WADL (there are even conversion utilities) which the API Portal will then use the converted wadl.

Special note some of the conversion utilities create broken references/tags which will cause issues for the PORTAL so you may need to find the best utility for your documentation or fix formatting.

Portal 4.x supports swagger out of the box,
