Trigger
Card Updated Trigger
Triggered when a specific card is updated
Action
Update Amplitude Cohort Membership
Incrementally update cohort membership by adding or removing ids. this action allows you to: - add new ids to an existing cohort - remove ids from an existing cohort - perform multiple operations in a single request
Why this helps
Segment decisions are revised in Trello but cohort membership keeps the previous version.
- Reflect revised segment decisions
- Preserve an auditable source card
- Reduce manual corrections
Setup
Build it in a few focused steps.
- 1Connect Trello and Amplitude in Notis once.
- 2Create an automation that applies only approved add or remove operations described in the updated card.
- 3Pick the Trello Card Updated Trigger for the specific card.
- 4Choose a report channel and test with one approved update.
Questions about this workflow
Can it add and remove users in one update?
Yes, when the card clearly provides both operations and valid identifiers.
What happens when the update is ambiguous?
Notis should report the ambiguity and leave cohort membership unchanged.
