Question

Is it possible to proxy destination tools (for example Mixpanel, FullStory, etc.) through my custom proxy when using Segment’s Custom Proxy or Custom Domain setup?

Product

Twilio Segment

Environment

Segment Console

Answer

No, destination tools cannot be proxied through your custom proxy. Custom Proxy and Custom Domain only override requests made to Segment-owned domains (cdn.segment.com and api.segment.io), and destination SDKs continue to load from and send data directly to their own endpoints, which cannot be customized. If you want to avoid loading destination SDKs on the client, you can switch supported destinations to Cloud Mode so that all events sent to Segment, through your proxy, are forwarded to the destination from Segment’s servers instead of through the device.
