Use SharePoint (or Nintex) workflows to create Planner tasks
We'd love to create Planner tasks generated by form-based workflows originating from documents stored within SharePoint document libraries. For example, users can start a workflow from a SharePoint file which displays a custom form (think checkboxes and drop-down menus) to create a Planner task for a specific user(s).

Nintex and Planner working together would be GREAT!
Would be great if colleagues can complete a form - which will go directly into a Planner
