Capital.com does not ask Tradeus to register anything. You create a key on your own settings page, and that key is what you hand over — so every customer's access is their own, and yours ends the moment you revoke it.
- 1Turn on two-factor authenticationCapital.com will not offer the key generator until it is on. This is their rule, not ours.
- 2Settings → API integrations → Generate new keyYou give the key a label, set a password for the key, and optionally an expiry date.

API key, yourLogin, and theAPI key password— then pick Demo or Live.
The password is not your account password
It belongs to the key you just made. Nothing Tradeus stores can sign in to the Capital.com platform, and deleting the key in your settings ends Tradeus's access without changing anything else about your account.
Demo and live are separate
Capital.com keeps them on different hosts, and a key made on one is refused by the other. If a connection is rejected straight away, this is usually why.
Two things about Capital.com are worth knowing because they are unusual, and Tradeus already handles both. An order is acknowledged before it is decided — Capital.com answers with a reference and confirms the outcome separately — so a fill only appears in your log once the broker has actually confirmed the price. And an account can be in hedging mode, where an opposing order would open a second position rather than closing the first; Tradeus closes what is held instead, oldest first, so an exit never leaves a hedge behind.
