Did Anybody try generating MAC based token type instead of bearer? If so, please list the steps you did. Documentation does not talk about it much.
the support for MAC token profile can be enabled by going to the policy "OTK Variable Configuration". Within that policy the supported token type can be changed from "Bearer" to "MAC".
Please note that features such as OpenID Connect are not supported with that token type.
After switching the token type you can use the browser based test clients (authorization_code) and have a look how the token looks like.
There is not a lot of documentation because that token type has not received big traction yet.
I hope this helps!
