During the ClickBank signup process, you select an account nickname. Your nickname is the unique ID that allows us to accurately track all the transactions related to your account. You use your account nickname to sign in to ClickBank, and it appears as part of your payment links and HopLinks.
Your account nickname is visible to the customer every time we sell one of your products, and will appear on the memo line when we send you a check.
Once you open an account and select the nickname, the nickname for that account cannot be changed. If you are unhappy with your current account nickname, you can sign up for a new ClickBank account and close the existing account.
