Hi @Firefly1,
You can combine a couple of Graph API requests. I would suggest to use the List plans in a group and the list plan tasks methods.
I tried combining them into one with an expand, but Graph API does not seem to support that. Also filtering on tasks seems to be not supported. That's why I am using a Filter array action instead.
Below is an example
1. First Send an HTTP request action (groups connector) uses the uri below to retrieve all plan ids of a group:
https://graph.microsoft.com/v1.0/groups/@{variables('GroupId')}/planner/plans?$select=id
2. Apply to each uses result from the value property
outputs('Send_an_HTTP_request')?['body']['value']
3. Second HTTP request action retrieves the tasks per plan id
https://graph.microsoft.com/v1.0/groups/@{variables('GroupId')}/planner/plans/@{item()['id']}/tasks
4. Filter Array filters for tasks with a title which contains a certain word (Stored in a string variable called CertainWord)
From
outputs('Send_an_HTTP_request_-_Tasks')?['body']['value']
Filter Criteria
@contains(item()['Title'], variables('CertainWord'))
