# Triggers & Conditions

> Triggers start a workflow. Conditions branch it.

<Note>
  **Where to find this:** Inside any workflow, the first node (trigger) and any binary nodes you add (conditions).
</Note>

## Triggers

A workflow has exactly one trigger node, set when the workflow is created. The trigger defines the event that starts the flow.

### Available triggers

| Trigger                          | Fires when                                                 |
| -------------------------------- | ---------------------------------------------------------- |
| **Order placed**                 | A customer completes an order                              |
| **Customer created**             | A new customer record is created                           |
| **Points earned**                | Yuko credits points to a customer                          |
| **Points redeemed**              | A customer redeems a reward                                |
| **VIP tier changed**             | A customer moves between tiers                             |
| **Membership unlocked**          | A customer's membership becomes active                     |
| **Membership lost**              | A customer's membership ends                               |
| **Customer inactive for X days** | Customer's last activity exceeds the threshold             |
| **Birthday**                     | The current date matches the customer's birthday           |
| **Anniversary**                  | The current date matches the customer's signup anniversary |

### Choosing a trigger

* **Use *Order placed*** when the workflow should run on every order.
* **Use *Points earned*** when you want to react to specific Way to Earn campaigns.
* **Use *Customer inactive for X days*** for win-back automations.
* **Use *VIP tier changed*** for tier-based welcome / lifecycle flows.

## Conditions (Binary nodes)

A Binary node branches the workflow on a rule. Each has a *Yes* path and a *No* path. Stack them to build more complex logic.

### What you can branch on

* Customer attributes (tier, lifetime spend, country, tags)
* Points balance (greater / less than a threshold)
* Order attributes (value, item count, contains specific product)
* Membership status (active / paused / cancelled)
* Time elapsed since last action

### Example branches

* *Tier == Gold or Diamond* → send VIP-only email; otherwise send regular email.
* *Cart total > \$200* → issue a thank-you coupon; otherwise no action.
* *Has active membership* → skip; otherwise upsell.

## Best practices

<Tip>**Pick the most specific trigger you can.** A narrower trigger means fewer entries and cleaner analytics.</Tip>
<Tip>**Don't overload one workflow with conditions.** If you have more than 4–5 binary nodes, split into two workflows.</Tip>
<Tip>**Always send a test customer through end-to-end** before activating.</Tip>

## FAQs

<AccordionGroup>
  <Accordion title="Can a workflow have multiple triggers?">
    No — one trigger per workflow. Build a second workflow if you need a second trigger.
  </Accordion>

  <Accordion title="Can a customer be in multiple workflows at once?">
    Yes. Each workflow tracks its own entries independently.
  </Accordion>

  <Accordion title="What happens if a trigger event fires while a customer is already in the workflow?">
    By default, re-entry is blocked. You can override per-workflow.
