> 📍 **Where to find it:** Reach your customers → Flows → (open a Flow) → trigger block at the top

The trigger is the event that makes a contact enter the Flow. Madyis Hub offers several entry points: a CRM event, a scheduled import, an entry URL (webhook) or a manual launch.

## How it works

For event triggers, Madyis Hub continuously listens to what happens in your account and automatically enrolls the right contact as soon as the event occurs. By default, a contact enters a given Flow only once (re-enrollment policy "never"), to avoid following up with them in a loop. You can relax this rule in the Flow settings.

## Step by step

1. Open the Flow, then click the trigger block at the very top of the tree.
2. In the right-hand panel, choose "How the flow starts".
3. Event triggers: New contact created · New conversation · Conversation resolved · Lead stage changed · Contact added to a folder.
4. For "New conversation" or "Conversation resolved", you can filter by channel (website, WhatsApp, Instagram, Facebook, email, SMS) — otherwise all channels count.
5. For "Lead stage changed", choose a specific target stage (or leave empty for any stage).
6. For "Contact added to a folder", select the relevant folder.
7. For a manual start, leave the type as "Manual" and enroll contacts yourself with "Test" or "Launch for a folder".

## Good to know

- The "Lead stage changed" trigger is ideal for reacting when a lead moves to "Qualified" in your Pipeline.
- Some steps (reminder, assignment, AI) only work if the Flow starts with a conversation: the editor warns you if that's not the case.
- The default re-enrollment is "once ever": no risk of following up with the same contact twice.
