Use the Field Changed filter brick whenever you want to trigger a flow from the update of a Podio Items Field value.
This Filter brick is very important when triggering an Update Flow when a Podio Item Field is changed. This will prevent the flow from running when ANY field is updated and keep it specific to the conditions thus preventing duplicates.
For example:
Start the Update Flow and add this Field Changed filter. Set to the specific Podio field that needs to be updated.
Then add the Field Value Match filter and set to the specific Podio field value that would be changed and the value it should match.
