Hello, The only way I found to accomplish this is by running a heavily customized playbook.  I would have hoped this would be in the Approval REST API or administrator interface to respond to all specific running prompts, but I couldn't find any method other than cancelling all playbooks or a customized playbook. Here's the short and sweet of it and I'll dig a little deeper after.   Filtered REST container call>REST container call for playbook_runs>list out running playbooks>REST playbook_run cancel API.  This will cancel only specified playbooks running in specified containers.   Here's the long and sour of it.  I've probably over-complicated it, but sadly that's my method of operation.  All rests are using the Phantom http app. Filtered REST call - Perform a "Container Call" with a "Query for Data" such /rest/container/?_filter_name="Test Container Names". The output returns the containerIDs for all query matches. Playbook Runs REST call - On the "Query for Data" doc, there's a container pseudo field "playbook runs" for "playbook_runs".  Feed the containerIDs to this with "/rest/container/{0}/playbook_runs" in a format block. This outputs all playbooks that ran on a container.  Note that this may need multiple page calls with "/rest/container/{0}/playbook_runs?page=n".  I performed this in the Global Block editing section with my own functions and leveraging callbacks to tie it in to the action blocks. List Running Playbooks - Now that you have a list of all playbooks running from the previous step, I pulled the playbook ID, status, and message.  Using the defined functions in the global block, I gathered all these IDs, statuses, and messages into their own list and used a custom function playbook API call so I can hook back into the visual editor.  In the custom function, I whittle down the list of items to just what I want to cancel, then pass that out of the custom function. REST playbook_run cancel API - Now with the list of playbook run IDs in hand, I can leverage the Run Playbook endpoint which allows a running playbook to be cancelled.    This is my ugly way of "responding" to multiple hanging playbooks or unnecessary prompts without responding one by one or cancelling everything.     ...
