I am using Kong Community Edition where I would like to implement OAuth2 introspection with few Routes. We have HashiCorp Vault as an Authentication server which will provide OAuth2 tokens.
I am aware of Kong ’ OAuth 2.0 Introspection’ plugin which provide this functionality however it is only supported with Kong Enterprise Edition.
I have found the article where it is possible to implement this at nginx level however this will apply the OAuth for everything:
Are there any alternative ways to implement this?
