is there a way to send a link in the form of a button in an email to the user which when clicked updates the value of a list.
Hi Jo, When you are sending something to a user that you need them to respond to you would use a task action. In the task action you can configure the notification to have a button with a link. The button would usually be an Approve or Reject or have multiple buttons. When the button is clicked the workflow that sent the task would continue. You can then have an update item action that would update an item in a list. There are many threads on the Community site in regards to formatting the notification email. Here is just one: https://community.nintex.com/message/10075
