Your API credential is the entire security boundary between a trading tool and your money. Everything else is commentary. This is the operational manual: what each permission actually enables, why withdrawal access should never be granted to any tool, the uncomfortable reason a trade-only key is bounded rather than safe, and a step-by-step revocation drill for the day something looks wrong.
Most explanations of trading software are either marketing abstraction or engineering documentation. This is the middle: what actually runs where, which of the three parties can do what, what an API key really is, how the software updates itself without you redeploying, and — the part nobody writes — exactly what happens when your instance dies, your broker goes down, or you revoke access.
A TradingView webhook is not a connection to your broker. It is an unauthenticated HTTP POST from a third party to a public endpoint you own, delivered with a three-second budget and no guarantee it arrives at all. Everything that determines whether it works lives in what you build behind that URL. This is the full reference: the alert-to-order flow stage by stage, how to design a payload, the security model TradingView does not give you, and the failures that only show up in production.
Every automated trading tool claims it never touches your money. Most people can't evaluate whether that's true. This is a security-model breakdown of what the claim actually means — you connect your own brokerage with your own API keys, the software can place orders but has no custody and no withdrawal rights — and, more usefully, exactly how to verify the access scope of any trading tool before you trust it. The most credible version of 'we can't touch your funds' is the one you can check yourself in your broker's settings.
