# On routing form fallback hit

> Subscribes when a routing form uses its fallback route.

`calcom.onRoutingFormFallbackHit` subscribes when a routing form uses its fallback route.

```ts automations/on-routing-form-fallback-hit.automation.ts theme={null}
import { automation, markSignificant } from "automate.ax"
import { calcom } from "automate.ax/calcom"

export default automation("On routing form fallback hit", () => {
  const event = calcom.onRoutingFormFallbackHit()
  markSignificant(event)
})
```

## Event

| Field               | Type                          | Required |
| ------------------- | ----------------------------- | -------- |
| `createdAt`         | `string (date-time)`          | Yes      |
| `payload`           | `object`                      | Yes      |
| `payload.formId`    | `string`                      | Yes      |
| `payload.formName`  | `string`                      | Yes      |
| `payload.responses` | `Record<string, JSON value>`  | Yes      |
| `payload.teamId`    | `integer \| null`             | No       |
| `triggerEvent`      | `"ROUTING_FORM_FALLBACK_HIT"` | Yes      |

Additional provider fields are preserved.

Automate.ax creates and maintains the Cal.com webhook, verifies `x-cal-signature-256`, and deduplicates provider retries. Use `calcom.onEvent` when one automation should receive every supported Cal.com event.
