Paddle webhook and supabase user sync edge

Event-driven billing sync without server

CLONE RECIPE INTO WORKSPACE View Architecture

Direct Answer & Architecture Summary

Any Frontend / Mobile apps hit CORS and credential limits when calling Paddle and Supabase. Edge receives Paddle webhook and updates Supabase in one flow. Use one RealComposer edge URL with OPTIONS handling, client tokens, and vault injection.

The Problem Solved

Why Paddle webhook and supabase user sync edge is hard without an edge proxy

Calling Paddle and Supabase directly from Any Frontend / Mobile risks leaked secrets, CORS blocks, or oversized JSON that slows rendering.

Critical Security & Operational Risks:

Exposed API keys in Any Frontend / Mobile bundles or DevTools
Sequential upstream calls on slow mobile networks
Third-party rate limits and surprise billing spikes

Architecture & Step-by-Step Implementation

How RealComposer Solves This at the Edge

Store credentials in Secret Vault

Save PADDLE_API_KEY, SUPABASE_ANON_KEY in RealComposer.

Configure edge pipeline

Add upstream steps with vault header injection and map the response fields your client needs.

Call from Any Frontend / Mobile

Use your workspace edge URL with a restricted client token.

                    const res = await fetch('https://realcomposer.com/v1/workspace/paddle-webhook-supabase-sync-edge', {
  headers: { Authorization: 'Bearer rc_live_client_token' }
});
const data = await res.json();

Frequently Asked Questions

Developer Questions & Troubleshooting

Is it safe to call Paddle from Any Frontend / Mobile?

Only if secrets stay off the device. RealComposer injects credentials on the server edge so clients never hold production keys.

Does RealComposer add latency?

Cloudflare edge execution adds a few milliseconds; caching can answer repeat calls in under 10ms.
