I am trying to configure a way for users who get a task assigned to them to receive an automated email after the task is reassigned to them. I'm using IBM BPM 8.5, would anyone know how I could achieve that?

Hi!

First you must have your server configured to send emails: https://www.ibm.com/support/knowledgecenter/SSFTDH_8.5.7/com.ibm.wbpm.admin.doc/topics/tadm_portal_email.html

Then you need to configure user emails. Either you tell the user to configure email and tick the check box "Send me an email when I have a new task assignment" in their Process Portal themselves or you can as administrator in Process Admin - Bulk user attribute assignment set these settings for them (see attached screen shot).

If you want to script email configuration you can use the Organization API and the call Set User Preference: https://hostname:port/rest/bpm/wle/v1/user/taube?action=setPreference&key=Task+Notification&value=false Documentation here: https://www.ibm.com/support/knowledgecenter/SSFTN5_8.5.7/com.ibm.wbpm.ref.doc/rest/bpmrest/rest_bpm_wle_v1_user_usernameorid_put.htm
