@DevashishK3781 Hi Devashish, I created a created with Java function which will generate the JWT assertion and use a Datapage to refer it under a property in the Auth Profile Rule. Couldnt find any other standard solution. Actual Java code as shown below. The java takes the clamset attributes as parameters such as aud, jti, exp, iss etc. In the Auth profile you can refer property instead of s Token Profile rule where I used a data page and property reference. The data page is sourced with a datatransform which in turn calls the functions. I hope this makes sense.
