On subscriber bounced

kit.onSubscriberBounced subscribes when a subscriber address hard-bounces.

automations/on-subscriber-bounced.automation.ts

import { automation, markSignificant } from "automate.ax"
import { kit } from "automate.ax/kit"

export default automation("On subscriber bounced", () => {
  const event = kit.onSubscriberBounced()
  markSignificant(event)
})

Event

Field	Type	Required	Description
`id`	`string (UUID)`	Yes	Stable event identifier used for deduplication.
`type`	`"subscriber.bounced"`	Yes	Kit provider event type.
`created`	`string (date-time)`	Yes	When the event occurred.
`data`	`object`	Yes	Provider payload for this event.

data.subscriber contains the bounced subscriber. Provider snake case fields are exposed as camelCase. Subscriber custom-field keys under fields are preserved exactly. Automate.ax creates and maintains one account-level Kit webhook endpoint, verifies the timestamped X-Kit-Signature against the raw body, and deduplicates each event by id. Kit can batch up to 100 same-type events in one delivery; each event starts independently. Use kit.onEvent when one automation should receive every available event.
