You will need a couple of things from Bamboo to log in properly. You require your Bamboo API Token and your userID. Especially if you're a manager with direct reports you require your userID to prevent fetching the booked holidays of your reports.
Go to the API Token page on Bamboo to create a new API token and paste it here. This page is also accessible from your profile icon in the top right of your Bamboo page.
When logged in to Bamboo click the "My Info" button. In your address bar it should now show your UserID to use. e.g. mycts.bamboohr.com/employees/employee.php?id=551Paste the ID number into the field above.
