After your GDAX account is created at gdax.com, sign in and create a GDAX API key, secret, and passphrase. These credentials are required in order to connect to GDAX via the TT platform.
Note: Multiple API keys and secrets can be created for a single GDAX account.
To create a GDAX API key:
To create an API key, hover on the list icon on the right corner of the Exchange screen and select API.
Then click Create API Key to create and display the passphrase, new API key, and API secret. Copy or store these values on your computer or device.
Note: This is the only time your API secret will display.
Note: If you do not have administrator permissions in the Setup application on TT, then provide your risk administrator with your API key, secret, and passphrase. If you trade for yourself and have administrator permissions in Setup, you can log in to the Setup application and create your trader ID for connecting to TT using your API key, secret, and passphrase.
