Overview

By proxying requests to Converge through your own domain, Converge is no longer treated as a third-party script. This has the following advantages:
  • First-party cookies When Converge runs on your main domain, we automatically set a first-party cookie. First-party cookies are not restricted by browser privacy features like Apple ITP. They are longer-lasting, allowing you to track longer user journeys.
  • Bypassing ad blockers Converge’s domain can be blocked by ad blockers based on our domain name. Using your own domain lets you bypass these ad blockers.

​
Installation instructions

There are two parts to proxying requests to Converge:
  • Hosting the script on your own domain By proxying requests to https://static.runconverge.com/pixels/*.js the Converge script is loaded through your domain.
  • Proxying the tracking requests By proxying requests to https://app.runconverge.com/api/tr/* the tracking requests are sent through your domain.
Ensure that the proxy sets the X-Forwarded-For header to the original IP address of the request.
Ensure that the proxy sets the X-Forwarded-Host header to the domain name of your proxy.
To let Converge know your proxied domain, update your Converge pixel snippet as follows:
1

Update the src of the Converge script to point to your domain. Replace xxxxxx with your Converge pixel public token.
<script src="https://yourdomain.com/cvg/static/pixels/xxxxxx.js" async></script>
2

Include the proxy call to configure your proxied endpoints for static and tracking requests.
cvg({method: "proxy", tracking: "https://yourdomain.com/cvg", static: "https://yourdomain.com/cvg/static"});
This should happen before any tracking calls.
This would yield the following updated snippet: 
<script src="https://yourdomain.com/cvg/static/pixels/xxxxxx.js" async></script>
<script>
window.cvg||(cvg=function(){cvg.process?cvg.process.apply(cvg,arguments):cvg.queue.push(arguments)},cvg.queue=[]);
cvg({method: "proxy", tracking: "https://yourdomain.com/cvg", static: "https://yourdomain.com/cvg/static"});
cvg({method:"track",eventName:"$page_load"});
</script>

Setting up a proxy through Vercel rewrites

If your site is hosted on Vercel, you can use the vercel.json configuration file to easily set up a proxy to Converge. 
{
  "rewrites": [
    {
      "source": "/cvg/static/:path*",
      "destination": "https://static.runconverge.com/:path*"
    },
    {
      "source": "/cvg/:path*",
      "destination": "https://app.runconverge.com/api/tr/:path*"
    }
  ]
}
Update your Converge pixel snippet to the following: 
<script src="/cvg/xxxxxx.js" async></script>
<script>
window.cvg||(cvg=function(){cvg.process?cvg.process.apply(cvg,arguments):cvg.queue.push(arguments)},cvg.queue=[]);
cvg({method: "proxy", tracking: "https://yourdomain.com/cvg", static: "https://yourdomain.com/cvg/static"});
cvg({method:"track",eventName:"$page_load"});
</script>
After deploying the changes, verify that
  • static scripts like the Converge pixel and GTAG’s load from your own domain
  • tracking requests to /tr/* are proxied through your domain
  • the response headers from the /tr/track call include the Set-Cookie header which sets a __cvg_1p_uid cookie
