Brokers & API Connections

API key not accepted

Fix rejected API keys for IG and other broker integrations that require them.

Last updated 3 September 2026

API keys are environment-specific. A key created for IG Demo will not work on Live, and vice versa. Copy the full key with no extra spaces.

  1. Log in to your broker's API or developer settings (for IG: My IG → Settings → API).
  2. Create a new API key for the correct Live or Demo environment.
  3. Paste the key into Trade Optic's secure connection form only — never share it elsewhere.
  4. If the old key may be compromised, revoke it in your broker settings after connecting.
Never send your broker password, complete API key, authentication token or payment details through email, direct messages or support chat. Only enter connection details inside Trade Optic’s secure broker-connection form. If a credential may have been exposed, revoke it through your broker immediately.
