## Triggers

What starts a flow. One per automation.

| Trigger                             | Fires when                                                                                                        |
| ----------------------------------- | ----------------------------------------------------------------------------------------------------------------- |
| **Customer sends a message**        | Any inbound message on a channel                                                                                  |
| **Customer taps a template button** | Someone taps a button in a WhatsApp template                                                                      |
| **New comment on a post**           | A comment arrives — can be limited to Facebook only or Instagram only                                             |
| **Lead is created**                 | A new lead appears                                                                                                |
| **Lead stage changes**              | A lead moves between [pipeline stages](/help/crm/leads-pipeline)                                                  |
| **Order is placed in your store**   | A WooCommerce order — see [WooCommerce](/help/integrations/woocommerce)                                           |
| **Triggered by AI / manual only**   | Nothing starts it automatically; it runs when an agent calls it as a [tool](/help/ai/tools) or you run it by hand |

## Variables

Any field can pull a value from the trigger or an earlier block. Type `{{` or use **Insert
a variable** — it lists what is actually available at that point in the flow, which is
faster and safer than typing a path from memory.

Inputs collected by an [AI tool](/help/ai/tools) arrive as `{{trigger.<name>}}`.

## Before you publish

The validation panel blocks publishing on real problems — an unconnected block, a required
field left empty, a variable that does not exist at that point. Fix what it lists; it is
checking things that would otherwise fail silently at run time.
