We're looking at integrating Recruit with a WordPress site and we're investigating how to push back associations between a job opening and a candidate. 

Assuming the user is logged in to WordPress so we know their email address, and that same user is already registered as a candidate in Recruit, how can we using the API create an association between the Job Opening ID and the email address of the user? Would we need to do a lookup of their candidate ID first and then use the associateJobOpening API call to link them?

Any help, gratefully received.
