"Send message to a user" is an efficient way to send information gathered in a flow to a specific recipient. For example, a recipient may want to be alerted when a flow user has asked a question or escalated an incident. The flow will then send the necessary information to a pre-selected recipient or a user specified under an attribute (i.e if someone selected a user from the "Select a user" functionality).

In the message builder, add all the parts you want to send to the current flow user at that time. In the example below the user has just finished a section of onboarding:

​

Click to add the 'send message to user' part at the bottom of the parts list in the message builder:
​

Click 'Choose recipient' in the message part:

Then configure your settings:

To send to a specific user, for example someone in the onboarding team, simply type in a user's Flip ID. This can be found in the admin console, under users>user's profile. 

Send to user stored in user attribute will allow you to send a message to a user saved under a specific attribute. The best way to save a user under an attribute is to use the "Select a user" setting under a button option. Simply create a message in the flow which invites the flow user to select someone from the directory:

Then add a button and program the button settings like this:

With this set up, the flow user will be sent a message like below. When they click the "Select user" button, it will launch a directory of user in their app:

They can then choose a recipient, which will then be assigned as a value to the attribute. So in my example, the recipient selected from the directory will be saved under {{$onbaording_leader}}. If I wanted to send a message from the flow to the recipient, I would configure my settings like this:

Once you're happy with your recipient, add your own text to that message part that you wish to send to the set/specific recipient:

This message will now be sent when a flow user triggers it. The above example would look like this:
