Asana: Possibility to bookmark users tasks

I would like to add link from mine application to users tasks in asana.

What I found out asana has a following URL for user tasks:[corewalking]({SOME_ID}/{SOME_ID}

Unfortunately SOME_ID is not a user id, but it is something different.

Is there a possibility to get this ID (SOME_ID) through asana rest API ?

And what exactly SOME_ID means ?

The first ID is the project, and the second is the task ID. Does this help?
I believe the My Tasks view link is special, and the ID in there is not the user ID. What do you need exactly?
