  • Use the Event Type filter to separate add and remove flows
  • Filters are optional — leave them blank to fire on every membership change

Best Practices​

  • Build separate workflows for add vs. remove using the Event Type filter
  • Use the Group Name or Group No. in CRM filter to target a specific group
  • Test by adding and removing a test member from a connected group

FAQs​

Can I tell whether a member was added or removed?​

Yes. Use the Event Type (add or remove) filter, or branch your workflow based on it.

Do I have to add filters?​

No. Filters are optional. Without them, the trigger fires on every add and remove event across your groups.
