On Vercel feature flag event - Automate.ax

vercel.onFeatureFlagEvent starts an automation for any event in this Vercel lifecycle family.

automations/on-feature-flag-event.automation.ts

import { automation } from "automate.ax"
import { vercel } from "automate.ax/vercel"

export default automation("On Vercel feature flag event", () => {
  const event = vercel.onFeatureFlagEvent()
  event.transform((value) => {
    if (value.type === "flag.created") return value.payload.flag.slug
    return value.type
  })
})

Input

The trigger accepts optional static account selection. Without it, Automate.ax uses the project’s Vercel OAuth binding.

Output

Every event includes id, createdAt, region, type, and payload. The discriminated union covers flag and segment create, update, and delete events with typed current, previous, patch, and deletion fields.

Provider behavior

Automate.ax verifies Vercel’s signature, routes the event to the matching installation, and deduplicates each delivery by event ID.
