User's BrowserDraftKings sportsbook — requests SDK + license

GET /api/sdk · GET /api/license

Cloudflare Worker/api/sdk → proxies gc-html5.js  ·  /api/license → reads KV

Reads "gc_sdk_url" + "gc_license" from KV

KV Namespace: DK_SECRETSGeoComply manages SDK version + license — operator touches neither

SDK + license delivered to browser → SDK initialised

Operator Setup — 3 Steps

Create a KV Namespace

Run once in your Cloudflare dashboard or via Wrangler CLI. This is where GeoComply will write the license.

# Wrangler CLI
wrangler kv:namespace create DK_SECRETS

Bind the KV to your Worker

Add the binding to wrangler.toml. The namespace ID comes from step 1.

# wrangler.toml
[[kv_namespaces]]
binding = "DK_SECRETS"
id      = "<namespace-id>"

GeoComply pushes the license — you're done

GeoComply writes the license key to your KV namespace automatically and keeps it fresh. Operator never handles license rotation, SDK upgrades, or distribution.

# GeoComply does this for you:
DK_SECRETS["gc_license"] = <signed-license-token>
# TTL managed by GeoComply — always valid

Worker Code

api/sdk.js — proxies SDK from GeoComply CDN

export async function onRequestGet({ env }) {
  // SDK URL managed in KV by GeoComply
  const url = await
    env.DK_SECRETS.get("gc_sdk_url")
    ?? "https://cdn.geocomply.com/gc-html5.js";

  const js = await fetch(url);
  return new Response(await js.text(), {
    headers: { "Content-Type": "application/javascript" }
  });
}

api/license.js — serves license from KV

export async function onRequestGet({ env }) {
  // License written by GeoComply, never by operator
  const license = await
    env.DK_SECRETS.get("gc_license");

  return Response.json({ license });
}
