Example Webhook Server

This repository contains a simple Node.js server that demonstrates how to set up a webhook endpoint for ZeroDev's custom gas policy.

Overview

The server is built with Express.js and sets up a single POST endpoint that listens for incoming webhook requests. It listens on port 3030 by default.

When a request is received, the server logs the payload to the console and responds with a JSON object containing a proceed: true key-value pair, indicating that any incoming operation should be sponsored.

Installation

To install the server, clone the repository and run the following commands:

cd example-webhook-server
npm install
npm start

Example Request:

Here's an example of how you can send a request to the server using cURL:

curl -X POST http://localhost:3030/webhook \
-H "Content-Type: application/json" \
-d '{
