Flow History
You can check on a Flow after it has run and view the values for all of the fields – inputs and outputs – for every step in your Flow. This is the best way to confirm that a Flow is running properly or to figure out where an error is occurring.
The data is available to view for the last 7, 30, or 90 or more days depending on your subscription plan.
To use this feature, open a Flow that has run and click on the Flow History button at the far right of the toolbar, if the Flow History pane isn’t already visible. Click in the list to see the data that passed through the Flow for that particular execution.
If you don’t want to save the data for a Flow, you can opt out when you first save the Flow by unchecking the Save Data with Flow History checkbox. Or, you can turn it off at any time using the “Save Data” checkbox on the Flow History pane. Press the “Clear data” button to clear history.
