Triggered task landing page

I am considering using a triggered task to provide unsubscribe functionality for an internal email system.

The link would pass two parameters to the pipeline, username and subscribe = yes or no.

I have a couple of questions;
When the task has completed can I redirect to a web page rather than {“http_status_code”: 200} page?
Is it possible to encrypt the userid ?


@peter Reg encryption of user id, you can pass Base64.encode(“userid”) and in implementation side use Base64.decode(_userid) or another option I can think create an Rest Account and use account.username as done in the below post.
