Your 'User Id' is the 6 digit account number shown in the top left corner when you log in to the Affiliate Window website. The password is a 48 character long API password hash which can be found by clicking on Settings and then Manage API Credentials.
Please note: This is not the same as the 'ProductServe API Password'. If there is no 'Affiliate API Password' heading visible, please create a ticket from within your account and a member of the Technical Services team will generate a password for you.
