- Start monitoring from an existing task update
- Catch pending, confirmed, or dropped status changes
- Keep operational context in one report
Setup

- 3Choose Trello Card Updated as the trigger.
- 4Pick where status reports should be delivered.
- 5Test with a card containing one real transaction hash.
Questions about this workflow
