Beatport Download via Browser Tool

Download purchased Beatport tracks through the openclaw headless browser using CDP (Chrome DevTools Protocol).

Prerequisites

• openclaw browser running on 127.0.0.1:9222
• Beatport credentials (username + password)
• ws module at /opt/homebrew/lib/node_modules/openclaw/node_modules/ws
• Node.js runtime

Authentication Flow

Beatport uses a dual-auth system:

1. account.beatport.com — Django session (sessionid cookie)
2. www.beatport.com — NextAuth (__Secure-next-auth.session-token cookie)

Login Steps

1. Navigate to https://account.beatport.com/ via CDP Page.navigate
2. Fill username/password via Runtime.evaluate (use native input setters to bypass React controlled inputs)
3. Submit the login form
4. On the www.beatport.com tab, sign in via NextAuth:

// In browser context on www.beatport.com
fetch("/api/auth/csrf").then(r => r.json()).then(csrf => {
  const fd = new URLSearchParams();
  fd.append("csrfToken", csrf.csrfToken);
  fd.append("username", "USER");
  fd.append("password", "PASS");
  fd.append("callbackUrl", "https://www.beatport.com/");
  // Create hidden form and submit (fetch redirect fails cross-origin)
  const form = document.createElement("form");
  form.method = "POST";
  form.action = "/api/auth/signin/beatport";
  form.style.display = "none";
  for (const [k, v] of Object.entries(Object.fromEntries(fd))) {
    const inp = document.createElement("input");
    inp.type = "hidden"; inp.name = k; inp.value = v;
    form.appendChild(inp);
  }
  document.body.appendChild(form);
  form.submit();
});

1. Verify login: Account menu button should appear in navbar (no Create Account or Log In button)

Key URLs

Note: /my-beatport/downloads and /my-beatport/collection return 404. The correct paths are /library and /library/downloads.

Enabling Downloads in Headless Chrome

Headless Chrome cancels downloads by default. Enable via CDP on the browser-level WebSocket:

// Browser-level WS: ws://127.0.0.1:9222/devtools/browser/<id>
ws.send(JSON.stringify({
  id: 1,
  method: "Browser.setDownloadBehavior",
  params: {
    behavior: "allowAndName",
    downloadPath: "/path/to/download/dir/",
    eventsEnabled: true
  }
}));

Get browser ID from http://127.0.0.1:9222/json/version → webSocketDebuggerUrl.

Downloading Tracks

Step 1: Add tracks to download queue

On /library, each track has a re-download icon (svg[data-testid='icon-re-download']). Click each one to add to the download queue:

var icons = document.querySelectorAll("svg[data-testid='icon-re-download']");
icons.forEach(function(icon, i) {
  setTimeout(function() { icon.closest("button, div").click(); }, i * 500);
});

Step 2: Download from queue page

Navigate to /library/downloads. All queued tracks appear with a "Download All" button.

Step 3: Click Download All

Enable browser downloads first (see above), then click:

var btn = [...document.querySelectorAll("button")].find(b => b.innerText.includes("Download All"));
if (btn) btn.click();

The download arrives as a zip file (e.g. beatport_tracks_2026-04.zip).

Step 4: Unzip and clean up

cd /path/to/download/dir
unzip -o beatport_tracks_*.zip -d tmp/
mv tmp/*.mp3 .
rm -rf tmp/ beatport_tracks_*.zip

Download URL Format

https://zips.beatport.com/v1/download?token=<JWT_TOKEN>

The token is single-use and expires quickly. Always capture fresh from events.

Download URL Format

https://zips.beatport.com/v1/download?token=<JWT_TOKEN>

The token is single-use and expires quickly. Always capture it fresh from the Page.downloadWillBegin event.

API Access

Access Token

curl -s -H "Cookie: <cookies>" \
  "https://www.beatport.com/_next/data/<buildId>/en/library/downloads.json" \
  | jq -r '.pageProps.accessToken'

Library Data

curl -s -H "Cookie: <cookies>" \
  "https://www.beatport.com/_next/data/<buildId>/en/library.json" \
  | jq '.pageProps.dehydratedState.queries[].state.data.results[] | {name, id, artists}'

Build ID

curl -s "https://www.beatport.com/" | grep -o '"buildId":"[^"]*"' | head -1

Common Pitfalls

1. Cross-domain navigation fails with Page.navigate — Use location.href = "..." via Runtime.evaluate instead
2. React controlled inputs don't respond to .value = — Use native input value setter:

   var input = document.querySelector("input[name=username]");
   var nativeSetter = Object.getOwnPropertyDescriptor(HTMLInputElement.prototype, "value").set;
   nativeSetter.call(input, "username");
   input.dispatchEvent(new Event("input", { bubbles: true }));

1. Node.js string escaping in -e — Use String.raw\...\` template literals, or write code to a file and run with node file.js`
2. Free account download limit — 20 downloads per track. "Unlimited re-downloads" requires Beatport Streaming subscription
3. CDP exec timeout — openclaw kills long-running node processes (~10s). Keep CDP operations short; use background: true + process poll for longer waits
4. curl path — Use /usr/bin/curl, not /opt/homebrew/bin/curl (may not exist)

CDP Helper Pattern

Write scripts to files to avoid shell escaping issues:

// scripts/beatport-cdp.js
const WS = require("/opt/homebrew/lib/node_modules/openclaw/node_modules/ws");
const http = require("http");

function getPage(filter) {
  return new Promise((resolve) => {
    http.get("http://127.0.0.1:9222/json", (res) => {
      let body = "";
      res.on("data", (c) => body += c);
      res.on("end", () => {
        const pages = JSON.parse(body).filter(p => p.type === "page");
        resolve(filter ? pages.find(filter) || pages[0] : pages[0]);
      });
    });
  });
}

function cdpEval(ws, expression) {
  return new Promise((resolve) => {
    ws.send(JSON.stringify({ id: Date.now(), method: "Runtime.evaluate", params: { expression, returnByValue: true } }));
    ws.on("message", (m) => {
      const d = JSON.parse(m.toString());
      if (d.id && d.result) { resolve(d.result); }
    });
  });
}

async function screenshot(ws, path) {
  return new Promise((resolve) => {
    ws.send(JSON.stringify({ id: Date.now(), method: "Page.captureScreenshot", params: { format: "png" } }));
    ws.on("message", (m) => {
      const d = JSON.parse(m.toString());
      if (d.id && d.result && d.result.data) {
        require("fs").writeFileSync(path, Buffer.from(d.result.data, "base64"));
        resolve();
      }
    });
  });
}

module.exports = { getPage, cdpEval, screenshot };

Format Compatibility

• CDJ-2000: MP3 or WAV
• Beatport download options: MP3, WAV, AIFF, FLAC
• Default is MP3; select WAV/AIFF on cart page or account settings if needed for CDJ compatibility
