How do I remove items from a dictionary created from a REST call in a SP 2013 designer workflow? I have seen actions for building dictionary and retrieving items but none for removing.
Not sure if you still need the answer to this or not, but you can clear out a dictionary by using the "Set Variable" action. First, you will need to create a new variable of the dictionary type. Leave it blank! When you need to clear out the dictionary that you were using for your REST call, set the REST dictionary to the empty Dictionary.
