Replit · AI-assisted webhook

Replit

Paste a ready-made prompt into Replit Agent, it reads your project and writes the webhook receiver to match.

Overview

Replit projects vary more than a single-framework builder, commonly a React frontend with a Node.js backend and PostgreSQL, though Replit itself supports dozens of languages. Replit Agent can search your existing codebase by file, function, or plain description, so the prompt below works whether you're extending an existing Replit blog or starting a new one. It also knows to store the webhook secret in Replit's Secrets panel, not a .env file, the way Replit projects actually keep credentials.

Requirements

A Replit project (existing blog, or a fresh Repl if building from scratch)
A database for article storage, PostgreSQL is Replit's built-in option
Access to Replit Agent to paste the prompt into

How to connect

Pick the prompt that matches your situation and paste it directly into Replit Agent.

AI Setup Prompt

Copy and paste into your project

Copy one of the two prompts below and paste it into Replit Agent.

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.
