Every tool you pay for has an API gap. The endpoints they publish. And the ones their own web app uses that they never documented. Skool. GoHighLevel. Half the platforms in your stack. There's always a feature the public API just doesn't cover. That gap is not a dead end. GHL's public API gives you 36 tools. Read contacts, trigger some basics. That's the ceiling they publish. But open browser dev tools inside GHL and watch what happens when you click. Every action fires a hidden request to itself. Create a workflow. Modify conditions. Build a sequence. It's all just requests. We pointed Claude Code at it and let it watch every click. It logged each endpoint, each payload, and wrapped them into a backdoor MCP server for GHL. Now Claude Code drives GoHighLevel the same way you would. Minus the clicking. 481 workflows. Built, pulled, modified. Without touching the dashboard once. The public API is the front door. The internal API is the whole building. Any SaaS that runs in a browser has this. Skool. Clay. Instantly. If it has a network tab, it has a backdoor. Comment "Backdoor" and I'll DM you the skill.
