# Trigger catalog

> See the main trigger types used in Workflow Machine and when each one is the right choice.

## Core trigger types

Workflow Machine includes several important trigger patterns that are useful across many workflows.

## Webhook

Use **Webhook** when another system should send data directly into the workflow.

Best for:

* custom integrations
* internal systems
* event-driven external tools

## Schedule

Use **Schedule** when time should start the workflow.

Best for:

* recurring digests
* periodic syncs
* recurring checks

## RSS

Use **RSS** when the workflow should react to feed updates.

Best for:

* research monitoring
* content tracking
* industry update digests

## App event triggers

Many integrations expose app-native trigger patterns.

Best for:

* inbox-driven workflows
* file event workflows
* form-response workflows
* record-change workflows

## How to choose the right trigger

The right trigger is the one that matches the natural beginning of the process.

If the workflow starts because something happened, use an event-style trigger. If it starts because time passed, use a schedule.
