Hey @Mary Clair Thompson!
Do you want to keep the flow’s history or are you okay deleting it?
There’s a delete button on the Flow page in the UI

yes so the question would be does that actually remove the history?

It deletes all objects associated with the flow (runs, tasks, logs, etc)

08/27/2020, 6:37 PMIs there a pythonic way to unregister?
ie the complement of flow.register()?

Nah
You’d need to instantiate a client and use a graphql mutation
Client.graphqlIf you wanted to contribute one we’d welcome the PR!
