v0 · AI-assisted webhook

v0 by Vercel

Paste a ready-made prompt into v0's own chat, it reads your Next.js project and writes the webhook receiver to match.

Overview

v0 is Vercel's own AI app builder, generating Next.js projects with Tailwind CSS and shadcn/ui, with an optional Supabase integration for the database. Since every v0 project is a real Next.js app, the webhook receiver it generates is a standard Next.js Route Handler, no different from one you'd write by hand.

Requirements

A v0 project (existing blog, or a fresh project if building from scratch)
A database connected for article storage, commonly Supabase, Vercel Postgres, or Drizzle in v0 projects
Access to v0's chat to paste the prompt into, it applies changes as patches to your existing project

How to connect

Pick the prompt that matches your situation and paste it directly into v0's chat.

AI Setup Prompt

Copy and paste into your project

Copy one of the two prompts below and paste it into v0's chat.

The prompt generates and deploys the code, but registering the deployed webhook URL in your VellumUp dashboard is still a manual step, your assistant can't do that part for you.

Open in Dashboard

Webhook reference

The prompt already covers signature verification and payload handling, but if you want the full technical reference, events, payload schema, HMAC verification, and code samples in 5 languages, live on its own page.
