| description | Learn how to set up a Cloudflare Worker to securely proxy your Sim API requests, protecting your API key from client-side exposure. |
Protect your Sim API key when making requests from client-side apps by using a Cloudflare Worker as a proxy.
This worker receives requests from your app, securely adds your SIM_API_KEY on the server, and then forwards the requests to the Sim API endpoints.
When to use a proxy:
- Your app makes Sim API calls from the browser (React, Next.js client components, etc.)
- You need to avoid exposing your API key in client-side JavaScript
- You need to handle CORS for browser-based requests
When you don't need a proxy:
- Server-to-server calls (Node.js backends, Python scripts, etc.) can call the Sim API directly
We provide a one-click-deploy Cloudflare Worker to simplify this setup. Find detailed instructions in our GitHub repo:
