The best way to authenticate with the Tableau API is with a Personal Access Token. This must be generated for an administrator account.
Personal Access Tokens expire after 15 days of inactivity, or after approximately 1 year. If this happens you will need to create a new Personal Access Token in Tableau and reconnect the integration in Trelica.
Click on your profile icon and choose My Account Settings:
Scroll down and find Personal Access Tokens.
Enter the name (we recommend Trelica), and click Create new token:
This will generate a new Token Secret. Click Copy to clipboard and then paste this into Trelica.
