On Vercel deployment rollback - Automate.ax

vercel.onDeploymentRollback starts an automation for the corresponding Vercel webhook event.

automations/on-deployment-rollback.automation.ts

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

export default automation("On Vercel deployment rollback", () => {
  const event = vercel.onDeploymentRollback()
  event.transform(({ payload }) => ({
    from: payload.fromDeploymentId,
    to: payload.toDeploymentId,
  }))
})

Input

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

Output

The event includes id, createdAt, region, its exact type discriminator, and a typed payload. payload.fromDeploymentId is replaced by payload.toDeploymentId; payload.project.id identifies the project.

Provider behavior

Automate.ax verifies Vercel’s signature, routes the event to the matching installation, and deduplicates the delivery by event ID. The event confirms that Vercel accepted the rollback. Traffic may still be switching.
