Approval Flow - How to make attachments optional

(1) ShareShare
ReportReport
Posted on by cebolamonica 44

Hello! In an approval workflow, I need for the approver to be able to approve one to four files at the same time (main file, with possible additional supporting documents).

 

When I configure the Approver Process, I have put in the Attachment 2 field the parameters that I have captured in the manual input for the possible second file that can be attached.

However, if in the manual input the user does not designate a second file, then the approval flow errs out.

Is there a way to make the second (and third, and fourth) attachments optional, so does it doesn't err out?

 

Thank you so much!

    If you build the Attachments as a JSON Array and then attach them as an array you won't need to specify the exact number of attachments.  You can switch to the array input using the button in the upper right hand corner of the attachment section of the approval dialog.  Take a look at the solution in this post for how to add attachments to an array.

    Hello @cebolamonica ,

    you have to store the attachments and their content into an array variable and then use that variable in the task action.

    To get all the attachments and append them into the variable use the code below, it's the format the 'Approval task' action expects. Just replace the <...> parts with your dynamic content. 

     

     

    {
 "Name": <DisplayName>,
 "content": <Attachment Content>
}
