Is there a way to get (check) if there is a response in a separate survey by a respondent taking my current based on their email address using a webservice? If so, how would this be setup? I seem to only be able to be able to get individual responses by responseId.

@HPowell,
If you are using a contact list, you can use the API to get the contact information which includes their response history. Then search the history to see if they completed the survey of interest.
