 # Stripe Multi-Environment Webhook Handler (SMEWH) 🌍💳
 
-[![Deploy to Cloudflare Workers](https://deploy.workers.cloudflare.com/button)](https://deploy.workers.cloudflare.com/?url=https://github.com/adshrc/stripe-multi-environment-webhook-handler)
-
 Struggling to handle dev, staging, demo, and other environments with a single Stripe Test Environment? Here's an easy and flexible solution!
 
 This Cloudflare Worker forwards incoming Stripe webhook events to the appropriate environment based on the `returnUrl` included in the event's `metadata` property.
 
 ## Requirements
 
-- Create the Cloudflare Worker
-- Create a Webhook in your Stripe Dashboard: https://dashboard.stripe.com/test/webhooks
+- Create the Cloudflare Worker and upload the `worker.js` contents or use this Button:
+
+  [![Deploy to Cloudflare Workers](https://deploy.workers.cloudflare.com/button)](https://deploy.workers.cloudflare.com/?url=https://github.com/adshrc/stripe-multi-environment-webhook-handler)
+- Create a Webhook in your Stripe Dashboard: https://dashboard.stripe.com/test/webhooks. Make sure to replace the original URL's Domain with the Worker Domain. In the end you should have something like this: `https://smewh.worker.dev/<originalPath>`
+
+- Add the `returnUrl` property in the `metadata` of every Stripe request your Server sends. It should be the URL of the originating server (e.g. `https://dev.your-server.com`)
 
-**IMPORTANT: You need to include the target path: `https://<workerDomain>/<targetPath>`**
-- Add the `returnUrl` property in the `metadata` of every Stripe request your server sends. It should be the URL of the originating server.
+## What the Worker actually does
 
-## Example
+Stripe sends a webhook event to your Worker, e.g. `https://smewh.worker.dev/stripe/webhook`, then the Worker:
 
-1. Stripe sends a webhook event to your Worker, e.g. `https://smewh.worker.dev/payment-processors/stripe/webhook-direct`
-2. The Worker extracts the `returnUrl` from `metadata.returnUrl` (e.g., `https://your-env.com`)
-3. The Worker forwards the original request (including the `stripe-signature` header for validation) to `https://your-env.com/payment-processors/stripe/webhook-direct`
-4. The Worker returns the response back to Stripe
+1. Parses the body, extracts `metadata.returnUrl` (e.g. `https://dev.your-server.com`)
+2. Forwards the original request (including headers!) to `https://dev.your-server.com/stripe/webhook`
+3. Returns the response back to Stripe
