Mantis Bug Tracker - Forums

I want to list tickets, add notes, close tickets etc, in my SVN. Using the SOAP API it is good, but can it requires the username and password for mantis login and is a bit annoying if I have to give it all the time, because there are multiple users(on mantis and on the SVN as well).

Can I use the SOAP API with IP(unique for all users) or an API key?
