Discovery Method

While using Codex with Playwright browser automation to edit GoHighLevel workflows, the system discovered GoHighLevel's private backend API that powers their native AI workflow builder.

How It Happened

  1. Codex was tasked with browser automation to edit GHL workflows
  2. Playwright had access to the network console and DOM
  3. The system intercepted API calls that GHL's frontend makes to their backend
  4. Discovered endpoint: backend.leadconnectorhq.com

Key Insight

GoHighLevel has an internal AI workflow builder agent that connects to their actual backend through APIs not publicly documented. When Playwright observed the network traffic during browser automation, it captured these API patterns.

Technical Details

  • Uses Playwright storage state JSON file from a real logged browser session
  • The frontend JavaScript exposes the workflow node graph package
  • Can be repackaged into a reusable skill similar to an "N8N edit skill"

Warning

This involves using undocumented private APIs. These endpoints could change without notice and using them may violate GoHighLevel's terms of service.
