How can i get task id of a task that is assigned to a User, I can not use tp!id

Are you looking for a specific task? or all tasks assigned to a specific user? You can try running a task report by user and add ID to the report. Then use the analytics node to retrieve the IDs.

Thanks! is there any other apporach other than running report and using Analytics node?

Ambrish, can you please explain your use case? Why do you need the task id?

I want to send an email once a task is assigned and email should contain link to the assigned task.

Have you considered using an Escalation? forum.appian.com/.../Escalating_a_Task

I think an escalation would work well. The only thing I would mention about that is that we have had limited success for the link to the task that gets included in the email opening the task in a pop-up as opposed to within a tab in the application itself.

Also, I could be wrong, but I believe that the smallest amount of time that an escalation can be triggered is one minute after the task is initiated, so there would be some delay between assignment and the email being sent.

A good work around for a timer to go to seconds is to put a decimal number in quotes I.E. (".2") to get to seconds. However, using a rule for the escalation which is always true I.E. "True" then it will happen immediately.

Each user can get an email sent to them when assigned to themselves or a group which has a link in the email. This can be done as part of configuration.

Also worth noting is that the task link in the email will send the user to the 'old' portal and not to tempo.
