Send mail when task is completed to recepient who submitted a form

[sad3011]

Hi!

I've created a flow which creates a task in planner when a form is submitted. This works fine.

Now I want to create a flow to send an email to the submitter of the form when the task is completed. The flow fails, because flow didn't know which FormID belongs to the completed task. 

Has anybody an idea?

Thanks!

Since this has to be done as two separate flows, you need to store the form submittors name/email somewhere.  You could put that in the description of the planner task perhaps.  Or you could use an excel spreadsheet or sharepoint list to keep an active list of task ID <-> submittor email.

Sounds like a good solution. So the trigger for my second flow would be "When Task is completed" and I will fetch TaskId and responders E-Mail from Sharepointlist. 

In first flow i need to add a step where i insert values in sharepoint list right? How can I tell sharepoint list that he should create a dependency between taskid and Responders email? Or is flow inteligent enough to fetch task id from sharepoint list with responders Email?

Correct, just a simple 'Create Item' action.  I would just create 2 columns in your list-  TaskID, and SubmittersEmail.  Then, with your second flow, you just get all items from the list and filter it on the taskID of the completed task.  Once you have that item, you can grab the email.
