You need to contact your account manager from your chosen job board and request XML credentials, this is a username and password different to your account logins.
Once you have the XML username and password go to Settings in Occupop.
Select your chosen job board and enter the username and password.
That's it, you are ready to go!
If there is a job board that you want to use not currently listed on Occupop let us know and we can set it up for you.
