Thanks @betteredbritain

You have navigated me to one place in documentation that helps me:

I was looking for this answer:

Whenever you schedule an API workflow Bubble generates a unique ID for that specific instance. The Schedule API workflow returns that ID so that you can reference that in a later step in the same workflow:

You can use this ID to cancel the API workflow at any time before it is scheduled to run by using the Cancel a scheduled API Workflow action.

So it means I have to store it somewhere in a special database and then later cancel the newest one. Brilliant! BTW Interesting if I can retrieve information from it. - that would be good as I actaully miss this feature to show user the running api workflows.

PS: I cannot use recurring workflows - for me one the most useless feature of whole bubble - as it doesn’t allow to create incidents more often than once per day. Apart from maybe 3-5 situations - all my recurring actions happen more often.
