Storyline course published in WP link to Moodle

Cheers,

Can anyone please tell me how I can have a Storyline 2 course import log in details from WP to Moodle so user has seamless experience?

That is, user signs into course through WP which creates a login in Moodle. They complete course content in Storyline through WP and on last page click Next to begin the test. Clicking Next should take user to Moodle where they will be automatically sign in and lead to test.

Any input is greatly appreciated!
