Connect Akto with Cloudflare Worker Proxy

Cloudflare is a global network security platform that provides CDN, DDoS protection, and API security services. Integrating Cloudflare with Akto enables automatic discovery of all APIs passing through your Cloudflare infrastructure, helping you maintain continuous visibility and protection of your edge-distributed APIs.

To connect Akto with Cloudflare, follow these steps -

---

Step 1: Deploy the Akto Data-Ingestion Service

Before configuring the Cloudflare Worker Traffic Connector, you need to deploy the Akto Data-Ingestion Service. Ensure that the service is running and accessible via a publicly available URL. Set up and configure Akto Traffic Processor. The steps are mentioned here. Ensure this instance is publicly accessible, as it will receive traffic logs from your Cloudflare Worker.

Step 2: Set Up Your Cloudflare Worker Script

1. Navigate to the Cloudflare Dashboard and select your account.

2. Go to Workers & Pages.

   
3. Click Create and choose Worker.

   
4. Click the Hello World button and deploy it.

   
5. Click Edit code and replace the default script with your Worker code that proxies traffic and mirrors it to Akto using service binding.

   export default {
       async fetch(request, env, ctx) {
           console.log("🚀 Worker handling:", request.method, request.url);
   
           // Detect WebSocket upgrade
           const upgradeHeader = request.headers.get("Upgrade") || "";
           const isWebSocket = upgradeHeader.toLowerCase() === "websocket";
   
           if (isWebSocket) {
           console.log("🔄 WebSocket upgrade detected");
   
           // Just proxy the connection
           const response = await fetch(request);
   
           // Clone headers only (no body to tee here)
           ctx.waitUntil(logTraffic(request, response, env, { isWebSocket: true }));
   
           return response;
           }
   
           // Normal HTTP(S) traffic
           let requestForFetch, requestForLog;
           if (request.body) {
           const [req1, req2] = request.body.tee();
           requestForFetch = new Request(request, { body: req1 });
           requestForLog = new Request(request, { body: req2 });
           } else {
           requestForFetch = request;
           requestForLog = request.clone();
           }
   
           const response = await fetch(requestForFetch);
           console.log("⬅️ Upstream response:", response.status);
   
           let responseForClient, responseForLog;
           if (response.body) {
           const [res1, res2] = response.body.tee();
           responseForClient = new Response(res1, response);
           responseForLog = new Response(res2, response);
           } else {
           responseForClient = response;
           responseForLog = response.clone();
           }
   
           ctx.waitUntil(logTraffic(requestForLog, responseForLog, env));
   
           return responseForClient;
       },
       };
   
       async function logTraffic(request, response, env, opts = {}) {
       try {
           console.log("📝 logTraffic running...");
   
           const reqContentType = request.headers.get("content-type") || "";
           const resContentType = response.headers.get("content-type") || "";
           const status = response.status;

           let resBody = "";
   
           if (!opts.isWebSocket) {

           reqBody = await readBodyAsText(request);
           resBody = await readBodyAsText(response);
   
           if (!(status >= 200 && status < 400)) {

               return;

               console.log("⚠️ Skipped log: no content-type in request or response");
               return;
           }
   
           if (!shouldCapture(reqContentType) && !shouldCapture(resContentType)) {

           console.log("📤 Sending log entry to webhook...");
   
           const aktoReq = new Request("https://<DATA_INGESTION_SERVICE>/api/ingestData", {

       } catch {
           return "";
       }
   }

Important Notes while editing the Worker code

• Replace <DATA_INGESTION_SERVICE> with the URL of the Akto Data-Ingestion Service you deployed in Step 1.

• Replace YOUR_AKTO_API_KEY with your API key from Akto. You can find it inside Akto Dashboard → Settings → Integrations → Akto API.

• If you are using Cloudflare Service Binding to send traffic to your ingestion service hosted inside a Cloudflare container, use the following line instead of a public URL:

  // use this line to send data internally to data ingestion service
  // hosted in your Cloudflare container
  await env.<CONTAINER_BINDING_VARIABLE_NAME>.fetch(aktoReq);
  
  // for example
  await env.data_inject_worker.fetch(aktoReq);

Step 3: Configure Worker Routing

If you'd like to route specific domains or paths through this Worker:

1. In the Cloudflare Dashboard, go to Workers & Pages.

2. Under Overview, select your Worker.

3. Navigate to Settings > Domains & Routes.

4. Click Add Route.

5. Select the appropriate zone (domain), and enter a route pattern such as:

   *.yourdomain.com/*

This ensures all traffic matching the route is intercepted and mirrored to Akto.

---

Step 4: Verify the Setup

1. Confirm that API traffic data (requests and responses) are captured on the Akto dashboard under the respective API collection.

2. Check logs of your Worker for any initialization or forwarding messages.

3. Go back to the Akto Dashboard.

4. Navigate to API Collections > Hostname.

5. You should start seeing the traffic from your Cloudflare Worker.
