To expand on what YuriK mentioned, if you're already authenticated to the REST API as a user with sufficient permission (i.e. an admin), it's actually pretty easy to get a session key for another user. See here:
This is the relevant portion:
"Log in as the specified user, and return a session key identifying the session created for the login. The authentication parameters can consist of... A login name only. This will succeed if the user associated with the call (via session key or cookies) has the permission "allow_switch_users" for the community."
So once you have the session key for the desired user, you can make the subscription call as that user.
Hi Adam,
Solution do work with Rest client. However when we try the same method from within endpoint it does not work. Can you please confirm.
Thanks,
Sachin
