After your GDAX account is created at, 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:

  1. Log in to your GDAX account.
  2. To create an API key, hover on the list icon on the right corner of the Exchange screen and select API.

  3. Only check the View and Trade Permissions checkboxes to set the API key permissions.

    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.

  4. Repeat this step to create additional API keys and secrets for the same GDAX account if needed.
  5. 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.
