# Triggers

A **Trigger** is what starts your workflow. Every workflow listens for an event or condition and fires the workflow when that condition is met.

### Trigger Types

Stacksync supports multiple built-in trigger types

#### Popular Triggers

| Trigger                      | Best for                                            |
| ---------------------------- | --------------------------------------------------- |

#### App Triggers

Stacksync supports app-specific triggers from your connected integrations. For example, firing a workflow when a new record is created in Salesforce or when a payment is received in Stripe.
